Method Detail

getDeclaringClass

Class getDeclaringClass()

getName

String getName()

getType

Class getType()

set

void set(Object obj,
         Object value)
         throws MetadataException

Sets the field represented by this PersistentField object on the specified object argument to the specified new value. The new value is automatically unwrapped if the underlying field has a primitive type. This implementation invokes set() on its underlying Field object if the argument is not null. OBS IllegalArgumentExceptions are wrapped as PersistenceBrokerExceptions.

Parameters:

obj - The target object (no proxy objects allowed).

value - The value to set.

Throws:

MetadataException - if there is an error setting this field value on obj

get

Object get(Object anObject)
           throws MetadataException

Returns the value of the field represented by this PersistentField, on the specified object. This implementation invokes get() on its underlying Field object.

Parameters:

anObject - - The object instance (proxy objects are not allowed here) which we are trying to get the field value from.

Throws:

MetadataException - if there is an error getting this field value from obj
