Method Detail

isWriteable

public boolean isWriteable(Object entity)

Specified by:

isWriteable in interface FieldAccessor

Returns:

false for read only or computed fields, true otherwise

createManagedSet

protected <T> ManagedFieldAccessorSet<T> createManagedSet(Object entity,
                                                          Set<T> result,
