Method Detail

getMinOccurs
```
int getMinOccurs()
```
Returns the value of xs:minOccurs.

getMaxOccurs
```
int getMaxOccurs()
```
Returns the value of xs:maxOccurs.

isCheckNullInput
```
boolean isCheckNullInput()
```
Returns the value of the propertyosd:checkNullInput.

getPathInAdaptation
```
Path getPathInAdaptation()
```
Returns the local absolute path.
In a table record, the local absolute path is the path that begins at the table root node (non-inclusive); otherwise, it is the path that starts at the dataset root node (inclusive). In the latter case, the path is the same as the one returned by getPathInSchema().

See Also:

getPathInSchema()

getPathInSchema
```
Path getPathInSchema()
```
Returns the absolute path of this node in the data model.

See Also:

getPathInAdaptation()

isComplex
```
boolean isComplex()
```
Returns true if this node is a complex element declaration.

isValueEqual
```
boolean isValueEqual(Object aFirstValue,
                     Object aSecondValue)
```
Returns true if the specified values are equal, according to the underlying XML Schema type.
For example, if the data model type is xs:date, both specified values must instances of Date. Also, equality checking for xs:date does not take time into account, due to the Java equality checking for Date. In contrast, equality checking for the type xs:dateTime in the data model would compare time.

Throws:

ClassCastException - if a specified value is not an instance of the underlying type.

isValueLessOrEqualTo
```
boolean isValueLessOrEqualTo(Object aFirstValue,
                             Object aSecondValue)
```
Returns true if first value is less than or equal to the second value, according to the underlying XML Schema type.

Throws:

UnsupportedOperationException - if underlying type does not support comparison.

ClassCastException - if a specified value is not an instance of underlying type.

isValueStrictlyLessThan
```
boolean isValueStrictlyLessThan(Object aFirstValue,
                                Object aSecondValue)
```
Returns true if the first value is strictly less than the second value, according to the underlying XML Schema type.

Throws:

UnsupportedOperationException - if the underlying type does not support comparison.

ClassCastException - if a specified value is not an instance of the underlying type.

isTerminalValue
```
boolean isTerminalValue()
```
Returns true if this node is terminal.
A node is terminal when:
- it is a field (a node of a simple type) that is not the descendant of a terminal complex (see isTerminalValueDescendant());
- it is a group (a node of a complex type) that is not the descendant of a terminal complex, and the data model specifies any of the following:
  1. maxOccurs > 1 (either an aggregated list or a osd:table);
  2. a value function, osd:function (see Computed Values);
  3. an access property, osd:access (see Access Properties).
Note: if inheritance is enabled, a terminal node value can be inherited.
See Also:

isTerminalValueDescendant()

isTerminalValueDescendant
```
boolean isTerminalValueDescendant()
```
Returns true if this node is the descendant of a terminal value node. This implies that the parent node is of a complex type and it is itself either terminal or a descendant of a terminal node.

See Also:

isTerminalValue()

isTerminalValueComputed
```
boolean isTerminalValueComputed()
```
Returns true if this node is a terminal node whose value is not directly stored in EBX® repository.
This is the case for a node declaring an osd:function, osd:association and osd:table.

isAutoIncrement
```
boolean isAutoIncrement()
```
Returns true if this node defines an auto-increment.
An auto-incremented node is specified in the data model using the the osd:autoIncrement element.

If this node is a table node, decomposes the specified osd:tableRef value into the primary key field values in the referenced table.

The following table gives some examples of decomposition:

Key fields	String representation (`aTableRefValue`)	returns
(xs:string)	"abc"	"abc"
(xs:int)	"123"	[Integer(123)]
(xs:int)	""	throws an `InvalidPrimaryKeyException`.
(xs:int)	"aa"	throws an `InvalidPrimaryKeyException`.
(xs:int \| xs:string)	"123\|abc"	[Integer(123), "abc"]
(xs:int \| xs:string)	"123\|abc\|abc"	[Integer(123), "abc\|abc"] (the second field is itself a foreign key, the second value can hence be itself decomposed)
(xs:int \| xs:string)	"aa\|aaa" (invalid integer field)	throws an `InvalidPrimaryKeyException`.
(xs:int \| xs:string)	"\|aaa"	throws an `InvalidPrimaryKeyException`.
(xs:int \| xs:string)	"" (empty string)	throws an `InvalidPrimaryKeyException`.
(xs:int \| xs:string)	"aaa"	Invalid, throws an `InvalidPrimaryKeyException`.

Parameters:: aTableRefValue - a string value that conforms to the primary key syntax.
Returns:: an array in which each element is extracted from the specified value and corresponds to the field at the same position in the primary key field array.
Throws:: InvalidPrimaryKeyException - if the specified value does not have the expected primary key syntax, or if a field value is null.; IllegalStateException - if this node is not a table node.; IllegalArgumentException - if the specified value is null.

getTablePrimaryKeyValues(String)

getTableOccurrenceRootNode
```
SchemaNode getTableOccurrenceRootNode()
```
If this node is a table node (see method isTableNode()), returns the root node of the record structure.
This method is used for accessing the internal structure of a table.

Since a table node is considered to be a terminal node, it does not provide direct access to its children. Instead, the child nodes can only be accessed through the root node of the record structure (the object that is returned by this method).

Returns:

the root node of the record structure, null if this node is not a table node

See Also:

isTableNode()

isTableOccurrenceNode
```
boolean isTableOccurrenceNode()
```
Returns true if this node is in a table record.

isHistoryDisabled
```
boolean isHistoryDisabled()
```
Specifies if the history is disabled for this node. Returns true if:
- this node is a table node and the property historyProfile is not set in the data model;
- the history is explicitly disabled on this node, in the data model;
- this node is a computed terminal-value;
- the type of this node is of type osd:password;
- an ancestor of this node in the data model has its history disabled.
Since:

5.5.1

See Also:

AdaptationTable.getHistory()

getAccessMode
```
AccessPermission getAccessMode()
```
Returns the static access mode of the current node. Access can be further restricted by specifying permissions.
For example, a function is read-only.

Note: If the node is neither terminal nor a terminal descendant, the returned mode is hidden. This does not imply that the node is not visible, but rather that it does not directly hold a value.

See Also:

Access Properties, isTerminalValue()

getCategory
```
String getCategory()
```
Returns the category that is defined in data model (attribute osd:category); returns null if no category is specified on the current node, nor on its ancestors.

getDefaultValue
```
Object getDefaultValue()
```
Returns the default value for the node that is defined in data model (attribute xs:default), or null if no value is specified.
This default value is typed according to type of the current node. That is, the default value specified in the data model must comply with the type of the associated element.

If the current node is an aggregated list (an element defining maxOccurs > 1) then the returned default value will be a new List instance containing a single occurrence of the default value defined in the data model.

getLabel
```
String getLabel(Locale aLocale)
```
Returns the localized label of this node.
The label is computed as follows:
1. If the data model defines a custom SchemaDocumentation, then the computed label is returned, if not, returns null;
2. Otherwise, the label that is defined statically on the current node in the data model is returned;
3. If no static label is defined, the name of this node is returned (the name is the last part of the node's path).
See Also:

SchemaDocumentation, getLabel(Session)

getDescription
```
String getDescription(Locale aLocale)
```
Returns the localized description of this node.
The description is computed as follows:
1. If the data model defines a SchemaDocumentation, then the description it computes is returned, if not, returns null;
2. Otherwise, the description that is defined statically on the current node in the data model is returned.
See Also:

getDescription(Session)

getLabel
```
String getLabel(Session aSession)
```
Returns the label of this node for the specified session.
The label is computed as follows:
1. If the data model defines a SchemaDocumentation, then the label it computes is returned, if not, returns null;
2. Otherwise, the label that is defined statically on the current node in the data model is returned;
3. If no static label is defined, the name of this node is returned (the name is the last part of the node's path).
See Also:

getLabel(Locale), SchemaDocumentation.getLabel(SchemaDocumentationContext)

getDescription
```
String getDescription(Session aSession)

getNode
```
SchemaNode getNode(Path aPath)
```
Returns the node at the specified path, or null if no node exists at the specified path.
If the path is relative, it is interpreted based on the location of this node. This method is equivalent to getNode(aPath, true, false).

If the path begins with "//", this method returns the first node that matches what follows. This syntax is not as efficient as absolute or relative notations.

See Also:

getPathInSchema()

getNode
```
SchemaNode getNode(Path aPath,
                   boolean tolerantRead,
                   boolean absolutePathBeginsAtRecordRoot)
            throws PathAccessException
```
Returns the node at the specified path, or null if the node does not exist and isTolerantRead is true.

Parameters:

aPath - if relative, it is interpreted based on the location of this node.

tolerantRead - if true, returns null when no node exists at the specified location; otherwise it throws PathAccessException.

absolutePathBeginsAtRecordRoot - if value is true, aPath is absolute, and this node is in a table, the root of the path is the table root node.

Throws:

PathAccessException - if no node exists at the specified path and tolerantRead is false.

getNodeChildren
```
SchemaNode[] getNodeChildren()
```
Returns the data model nodes defined directly under this node.
This method returns an empty array if the underlying type is a simple type or if this is a table node (see isTableNode()). If this is a table node, the method getTableOccurrenceRootNode() must be used to get the structure of the table.

Note: A node can have children and still be considered as "terminal" based on the definition given by the method isTerminalValue().

isAncestorMultiOccurrenced

displayOccurrence

String displayOccurrence(Object aValue,
                         boolean useLabels,
                         ValueContext aValueContext,
                         Locale aLocale)

Returns a user-friendly representation of the specified value.

Displaying values

A value can be displayed differently than its standard XML formatted value (see method formatToXsString) in order to be more relevant to the user:

Number and date formats: If the element is a number (xs:int, xs:decimal, etc.), or a date (xs:date, xs:dateTime, xs:time), it is formatted according to the formatting policy associated with the specified locale.
Value labeling: If useLabels is true and the element has a declaration that enables value labeling, as described in the table below.

Data model definition	Value label (if `useLabels = true`)
`xs:enumeration`	Label is either the value of the attribute `osd:label` or the content of the localized element `xs:documentation`, as specified in the data model.
`osd:tableRef`	For a foreign key constraint, the label is computed from the referenced record, if it exists, and its data model declaration. In order of preference: The elements `osd:tableRef/display` or `osd:table/defaultLabel`; If there is no such declaration, the label is the concatenation of the label of each primary key fields of the referenced record.
`osd:enumeration`	For a dynamic enumeration, the label comes from the target node, if it defines such labels.
`osd:constraintEnumeration`	For a programmatic enumeration constraint, the label is the string returned by the method `ConstraintEnumeration.displayOccurrence`. As a consequence, it may be localized.
`osd:constraintNomenclature` (deprecated)	For a programmatic nomenclature constraint, the label is the string returned by the method `NomenclatureItem.getLabel`, if the nomenclature item exists for the specified value.
other cases	No value labeling is performed, the method returns the formatted value.

Context limitations

If the specified ValueContext is a ProcedureContext, this method will throw an IllegalArgumentException when dynamic or programmatic labeling calls ValueContext.getValue(Path) using a relative path.

Parameters:: aValue - The value must be compatible with the type of the current node. If the current node specifies maxOccurs > 1, then the value must be an element of the List instance, not the List itself.; useLabels - If true and labeling is enabled, specifies to return the label associated with the value. See the table above.; aValueContext - Context that contains the value. It is used when the label to be returned depends on a contextual and dynamic resolution based on a relative path (see above).; aLocale - Locale for formatting numbers, dates or localized labels.
See Also:: getEnumerationList(ValueContext), getEnumerationNomenclature(ValueContext)

formatToXsString
```
String formatToXsString(Object aValue)
```
Returns the string that corresponds to the specified value. This method uses the underlying XML Schema type for performing the Object-to-String conversion.
For example, if the underlying type is xs:date, the specified record must be a Date instance and this method will return the XML Schema representation of this date.

Throws:

IllegalArgumentException - If the resulting string is not a valid XML string (this happens if a specified xs:string contains invalid XML characters).

ClassCastException - if the value is not of the expected Java type.

See Also:

parseXsString(String)

parseXsString
```
Object parseXsString(String aString)
              throws ConversionException
```
Returns the value that corresponds to the specified string. This method uses the underlying XML Schema type for performing the String-to-Object conversion.
For example, if the underlying type is xs:date, the string must conform to the XML Schema representation of dates (for example, "1999-05-31"). This method then returns a Date instance.

Throws:

ConversionException - if specified string is invalid with respect to the underlying XML Schema type.

getOccurrencesJavaClass
```
Class<?> getOccurrencesJavaClass()
```
Returns the default Class of the Java records of this data model node, null if this node is above a terminal node.

See Also:

isTerminalValue(), Mapping to Java

getJavaBeanClass
```
Class<?> getJavaBeanClass()
```
Returns the specific Java Bean class defined on this data model node (attribute osd:class) or null if no Java Bean has been defined and/or this node is not terminal. The difference with getOccurrencesJavaClass() is the fact that it returns null if no specific Java Bean has been defined in the data model. Therefore for simple types, it returns always null.

isTerminalValue(), isComplex(), Mapping to Java

createNewOccurrence
```
Object createNewOccurrence()
```
Creates a new Java object that complies to this node definition.
The returned value conforms to the following rules:
- If the element declaration includes maxOccurs > 1, the method does not take this fact into account (that is, it returns an element of the List, not a List instance).
- If the element is of a simple type and no default value is defined, it returns null.
- If the element is of a simple type and a default value is defined, it returns this default value (a clone of it, if this is a mutable object).
- If the element is of a complex type, it returns a new instance, either of the class specified in the osd:class="" attribute, or of a default internal class (such an instance may be accessed by executeRead(Object)).

executeRead(Object), getOccurrencesJavaClass(), Mapping to Java

executeRead
```
Object executeRead(Object aContainerOccurrence)
```
Reads the specified occurrence of the parent node and returns the value corresponding to this node.
Precondition: This node must be a descendant of a terminal node.

Example

A parent node declares maxOccurs > 1 and it refers to a complex. Hence, the parent value will be a Java List. For each object (occurrence) in the list, this method gets the value associated with this child node.

Parameters:

aContainerOccurrence - must be an occurrence complying with the data model definition of the parent node.

executeWrite(Object, Object), getOccurrencesJavaClass(), Mapping to Java

executeWrite
```
void executeWrite(Object aValue,
                  Object aContainerOccurrence)
```
Modifies the specified occurrence of the parent node by setting the specified value. As explained in the section Modification of mutable objects, to be persisted, the locally modified object must be set to the context.
Precondition: This node must be a descendant of a terminal node.

Parameters:

aValue - value to be set on the parent object, it must comply with the data model definition of this node; if it specifies maxOccurs > 1, the specified value must be a List.

aContainerOccurrence - parent object to be modified, it must be an occurrence complying with the data model definition of the parent node; the parent node must be a complex type; if it specifies maxOccurs > 1, the specified object must be an element of List, not the List itself.
