Class ERXRegExQualifier

java.lang.Object

er.extensions.eof.qualifiers.ERXRegExQualifier

All Implemented Interfaces:

EOKeyValueArchiving, EOQualifierEvaluation, NSCoding, IERXChainableQualifier, Serializable

public class ERXRegExQualifier
extends ERXKeyValueQualifier

Provides regular expression matching of attributes. You can also bind a WODisplayGroup queryOperator to matches and you should be able to have qualifier strings with "foo matches bar".

This class does not do any conversion of the regular expression, so you'd need to have your syntax in a way that is understood by both the java code and the DB.

Method Detail

evaluateWithObject

public boolean evaluateWithObject(Object object)

Description copied from class: ERXKeyValueQualifier

Overridden to handle case of in-memory evaluation of QualifierOperatorContains selector and a keyPath that has multiple toMany and/or manyToMany-flattened relationships resulting in arrays of arrays rather than an array of discrete objects. In that case the object is evaluated against a flattened array which gives the same result as SQL evaluation. Since legacy code may depend on workarounds to the incorrect behavior, this patch can be disabled by setting the property er.extensions.ERXKeyValueQualifier.Contains.flatten to false

Specified by:

evaluateWithObject in interface EOQualifierEvaluation

Overrides:
