Method Detail
get
public Object get(Object anObject) throws MetadataException(Code)
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 aretrying to get the field value from.
throws:
  MetadataException - if there is an error getting this field value from obj
See Also:   java.lang.reflect.Field

getDeclaringClass
public Class getDeclaringClass()(Code)

getName
public String getName()(Code)

getType
public Class getType()(Code)

set
public void set(Object obj, Object value) throws MetadataException(Code)
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).
Parameters:
  value - The value to set.
throws:
  MetadataException - if there is an error setting this field value on obj
See Also:   java.lang.reflect.Field
