DefaultCacheClient

public DefaultCacheClient(Class<?>... clazz)

Constructs a new client.

Parameters:: clazz - an optional shared cache class.

Method Detail

postmanaged

public void postmanaged()

Description copied from interface: Manageable

This method is called when the implementing adaptee has been managed either during post-registration of the corresponding adapter MBean or just after it is explicitly added to the adapter MBean during run-time.

Specified by:: postmanaged in interface Manageable
Overrides:: postmanaged in class Adaptee

unmanaged

public void unmanaged()
               throws Exception

Description copied from interface: Manageable

This method is called when the implementing adaptee is unmanaged either during pre-deregistration of the corresponding adapter MBean or just before it is explicitly removed from the adapter MBean during run-time.

Specified by:: unmanaged in interface Manageable
Overrides:: unmanaged in class Adaptee

Throws:: Exception - if the adaptee refused to be unmanaged.
