Method Detail

getDeclaringClass

public MetadataClass getDeclaringClass()

INTERNAL:

isEclipseLinkWeavedField

public boolean isEclipseLinkWeavedField()

INTERNAL: Used to determine if this is a field EclipseLink weaved into the class.

isValidPersistenceField

public boolean isValidPersistenceField(boolean mustBeExplicit,
                                       ClassAccessor classAccessor)

INTERNAL: Return true is this field is a valid persistence field. This method will validate against any declared annotations on the field. If the mustBeExplicit flag is true, then we are processing the inverse of an explicit access setting and the field must have an Access(FIELD) setting to be processed. Otherwise, it is ignored.

isValidPersistenceField

public boolean isValidPersistenceField(ClassAccessor classAccessor,
                                       boolean userDecorated)

INTERNAL: Return true is this field is a valid persistence field. User decorated is used to indicate that the field either had persistence annotations defined on it or that it was specified in XML.

setDeclaringClass

public void setDeclaringClass(MetadataClass declaringClass)

INTERNAL:

shouldBeIgnored

public boolean shouldBeIgnored()

INTERNAL Some fields should automatically be ignored, return true if this field should be ignored
