Method Detail

create

public static final SetterUtil create(GetterUtil g,
                                      SetterUtil.PlainSetter s)

Create a new SetterUtil, selecting the appropriate implementation type based on the type() of the GetterUtil g.

Parameters:

g - a GetterUtil that is the accessor for this slot

s - a PlainSetter that accomplished the actual modification

Returns:

a new SetterUtil instance that will handle this modification

setValue

protected java.lang.Object setValue(java.lang.Object val)
                             throws ConstraintFailure

Actually modify the value. Signals the change for the Monitors of the GetterUtil component.

Throws:

ConstraintFailure

set

public java.lang.Object set(java.lang.Object val)
                     throws ConstraintFailure

Description copied from interface: Setter

Set the value to an Object. Will call setString or setNode if appropriate.

Specified by:

set in interface Setter

Parameters:

val - the new value for the slot

Returns:

the Object that was Set
