                      Dictionary configuration)

Configure the handler.

Specified by:

configure in class Handler

getInstanceDescription

public InstanceDescription getInstanceDescription()

Get the instance description.

Specified by:

getInstanceDescription in interface Architecture

Returns:

the instance description

See Also:

Architecture.getInstanceDescription()

stateChanged

public void stateChanged(ComponentInstance instance,
                         int newState)

The instance lifecycle listener callback. When we receive the DISPOSED state, the architecture is unregistered from the service registry.

Specified by:

stateChanged in interface InstanceStateListener

Parameters:
