All Implemented Interfaces:

EOKeyValueArchiving, EOQualifierEvaluation, NSCoding, IERXChainableQualifier, Serializable

public class ERXQuicksilverQualifier
extends ERXKeyValueQualifier

ERXQuicksilverQualifier is a KeyValueQualifier that compares values with ERXStringUtilities.quicksilverContains. This only works as an in-memory qualifier and DOES NOT WORK if you try to use it with EOF.

boolean	evaluateWithObject(Object object) 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.

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
