Method Detail

create

public static MetaFieldRelationEntity create()

Creates a new MetaFieldRelationEntity with default values set

create

public static MetaFieldRelationEntity create(IDataProvider propertySource)

load

public static MetaFieldRelationEntity load(java.lang.String aEntityRelation,
                                           java.lang.String aReferenceEntity,
                                           java.lang.String aReferenceField,
