Class ProviderChangeEvent

Object
  oracle.adfmf.java.beans.ProviderChangeEvent

All Implemented Interfaces:

Comparable

public class ProviderChangeEvent
extends Object
implements Comparable

A "ProviderChange" event allow collection developers to emit events when a provider is created, updated, or deleted. Please note the convenience methods, but more importantly the absences of primitive types like; boolean, float, and double since those are not conducive to being good keys. Boolean due to the only T/F possible states, float and double because of their inherent precision idiosyncrasies (0.0001 vs 0.00011 vs 1.00E-3 vs 1.10E-3, ..)
