key - the key of the property being changed

oldValue - old value for the property

newValue - new value for the property

Method Detail

Returns:

source

isSourceOriginal

public boolean isSourceOriginal()

Returns true if the PropertySet returned from getPropertySet was the original PropertySet that had a property changed. If false, this means the PropertySet is a wrapper or otherwise dependent on another set, and didn't have its putValue() method called explicitly.

Returns:

true if this the original source

getKey

public ConstrainedKey getKey()

Get the key changed

Returns:

key

getOldValue

public Object getOldValue()

Get the old value

Returns:
