Method Detail

getOrderValue

public int getOrderValue()

Description copied from interface: Ordered

Defines a value to be used for assigning an order to services. A service with a lower order value will be processed before a service of a higher order value. This ordering is used, for example, to sort views in a client's UI. Please take care to ensure the value returned by this implementation does not collide with other implementations. The order value should be offset from one of the provided constants in this class. Such as Ordered.ORDER_DEFAULT_GROUP.

Returns:

the order value

createVmListener

protected VmUpdateListener createVmListener(int pid)

Description copied from class: VmListenerBackend

Creates a new VmUpdateListener for the virtual machine specified by the pid. This method is called when a new JVM is started or for JVMs already active when this Backend was activated.

Specified by:

createVmListener in class VmListenerBackend

Parameters:

pid - the process ID of the JVM

Returns:

a new listener for the VM specified by pid
