getListenerId

public byte getListenerId()
                   throws java.io.IOException

Description copied from interface: ICacheListener

Gets the listenerId attribute of the ICacheListener object

Specified by:

getListenerId in interface ICacheListener

Returns:

The listenerId value

Throws:

java.io.IOException

See Also:

ICacheListener.getListenerId()

setListenerId

public void setListenerId(byte id)
                   throws java.io.IOException

Description copied from interface: ICacheListener

sets unique identifier of listener home

Specified by:

setListenerId in interface ICacheListener

Parameters:

id - The new listenerId value

Throws:

java.io.IOException

See Also:

ICacheListener.setListenerId(byte)

handlePut

public void handlePut(ICacheElement element)
               throws java.io.IOException

Description copied from interface: ICacheListener

Notifies the subscribers for a cache entry update.

Specified by:

handlePut in interface ICacheListener

Throws:

java.io.IOException

See Also:

NOTE: This checks if the element is a puratory element and behaves differently depending. However since we have control over how elements are added to the cache event queue, that may not be needed ( they are always PurgatoryElements ).
