Constructor Detail

SearchComparator

public SearchComparator(com.orchestranetworks.schema.SchemaNode schemaNode,
                        Locale locale)

Method Detail

getLocale

public final Locale getLocale()

getSchemaNode

public final com.orchestranetworks.schema.SchemaNode getSchemaNode()

cloneMatching

public abstract SearchComparator cloneMatching(com.orchestranetworks.schema.SchemaNode newNode)

Clones the current algorithm. This method is called when the matching is executed on a foreign key.

Parameters:

newNode - a key in the table targeted by the foreign key.

normalizeValue

public String normalizeValue(String value)

Normalizes the value before any comparison. Default behavior: value is changed into lower-case. Can be overridden in subclasses to change this default behavior.

isNumericSupported

public boolean isNumericSupported()

Returns true if the algorithm supports numeric field. Default is true. Can be overridden in subclasses.

isDateSupported

public boolean isDateSupported()

Returns true if the algorithm supports searching in date-type fields. Default is true. Can be overridden in subclasses.

Since:

1.6.0

isNullSupported

public boolean isNullSupported()

Returns true if the algorithm supports the comparison of null for the pivot record. Default is false. Can be overridden in subclasses.

Since:

1.2.0

setParameter

public void setParameter(List<InputParameter> parameters)

Sets parameters for algorithm.

Since:

1.6.0

getParameter

public List<InputParameter> getParameter()

Returns a list of algorithm parameters.

Since:

1.6.0

isFullTableScanRequired

public boolean isFullTableScanRequired()

Searches only the most relevant records by default. Overriding this method includes all of the table's records in the search and may result in decreased performance. Default is false.

Since:

2.0.5

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
