Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`Object`	`getEnumerationValue()` Returns the current enumeration value if `isEnumerationNode()` is `true`; otherwise, returns `null`.
`Adaptation`	`getJoinOccurrence()` Returns the association record that links the current node with its parent.
`Adaptation`	`getOccurrence()` Returns the current record being displayed.
`HierarchyNode`	`getParentHierarchyNode()` Returns this node's parent node in the hierarchy.
`boolean`	`isEnumerationNode()` Returns `true` if the current node is an enumeration node.
`boolean`	`isOccurrenceNode()` Returns `true` if the current node is a table record node.
`boolean`	`isOrphansParent()` Returns `true` if the current node is the parent of an orphan.
`boolean`	`isRoot()` Returns `true` if the current node is the root of the hierarchy.
`boolean`	`isTarget()` Returns `true` if the current record is a record in the target table.
`boolean`	`isTerminal()` Returns `true` if the current node has no children in the hierarchy.

- Method Detail
  - getParentHierarchyNode
```
HierarchyNode getParentHierarchyNode()
```
    Returns this node's parent node in the hierarchy.
  - getOccurrence
```
Adaptation getOccurrence()
```
    Returns the current record being displayed.
    Warning: if this node is an enumeration node, a root or an orphan's parent, this method returns null.
    
    See Also:
    
    getEnumerationValue()
  - getJoinOccurrence
```
Adaptation getJoinOccurrence()
```
    Returns the association record that links the current node with its parent.
    Warning: if this node is an enumeration node, a root or an orphan's parent, or if there is no join dependency between the node and its parent, this method returns null.
    
    See Also:
    
    getOccurrence()
  - getEnumerationValue
```
Object getEnumerationValue()
```
    Returns the current enumeration value if isEnumerationNode() is true; otherwise, returns null.
    
    See Also:
    
    getOccurrence()
  - isEnumerationNode
```
boolean isEnumerationNode()
```
    Returns true if the current node is an enumeration node. An enumeration corresponds to a xs:enumeration element in the data model.
    In this case, the method getOccurrence() returns null.
    
    See Also:
    
    getEnumerationValue()
  - isOccurrenceNode
```
boolean isOccurrenceNode()
```
    Returns true if the current node is a table record node.
    In this case, the method getEnumerationValue() returns null.
    
    See Also:
    
    getOccurrence()
  - isOrphansParent
```
boolean isOrphansParent()
```
    Returns true if the current node is the parent of an orphan.
    In this case, the method getOccurrence() returns null.
  - isRoot
```
boolean isRoot()
```
    Returns true if the current node is the root of the hierarchy.
    In this case, the method getOccurrence() returns null.
  - isTarget
```
boolean isTarget()
```
    Returns true if the current record is a record in the target table.
    The target table is the table from which the hierarchy was built.
  - isTerminal
```
boolean isTerminal()
```
    Returns true if the current node has no children in the hierarchy.
