Method Detail

set

public void set(Object obj,
                Object value)
         throws MetadataException

Description copied from interface: PersistentField

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.

Specified by:

set in interface PersistentField

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

public Object get(Object anObject)
           throws MetadataException

Description copied from interface: PersistentField

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

Specified by:

get in interface PersistentField

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
