All Implemented Interfaces:
PersistentField, java.io.Serializable

public class PersistentFieldAutoProxyImplNew
extends PersistentFieldBase

PeristentField implementation that attempts to detect the nature of the field it is persisting.

First checks to see if it is a Field, then Property, then DynaBean

It will match in that order.

Method Detail

get

public java.lang.Object get(java.lang.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.

Parameters:
anObject - - the object instance which we are trying to get the field value from
Throws:
MetadataException - if there is an error getting this field value from obj
See Also:
Field

set

public void set(java.lang.Object obj,
                java.lang.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.

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