Constructor Detail

PersistenceDescriptor

public PersistenceDescriptor()

PersistenceDescriptor

public PersistenceDescriptor(PersistenceDescriptor pers)

The copy constructor.

Method Detail

getCMRFieldReturnType

public java.lang.String getCMRFieldReturnType(java.lang.String field)

classesChanged

public boolean classesChanged()

getParentDescriptor

public Descriptor getParentDescriptor()

getEjbBundleDescriptor

public EjbBundleDescriptor getEjbBundleDescriptor()

getRelationships

public java.util.Set getRelationships()

Get all CMR fields of this bean. All relationships are stored in EjbBundleDescriptor to avoid the complexity of keeping the two sets consistent. NOTE : To add or remove a relationship use EjbBundleDescriptor.

Return array of CMRFieldInfo objects for all CMR fields.

getCMRFieldInfoByName

public CMRFieldInfo getCMRFieldInfoByName(java.lang.String fieldName)

Return the CMRFieldInfo object for the given CMR field

invalidate

public void invalidate()

Ensures that persistence descriptor will regenerate its derived information after changes have been made to persistent characteristics.
