java.lang.Objectorg.picocontainer.monitors.AbstractComponentMonitor
public class AbstractComponentMonitor
A monitor
which delegates to another monitor.
It provides a default ComponentMonitor
,
but does not allow to use null
for the delegate.
It also supports a monitor strategy
that allows to change the delegate.
Constructor Summary | |
---|---|
AbstractComponentMonitor()
Creates a AbstractComponentMonitor with an instance of NullComponentMonitor . |
|
AbstractComponentMonitor(ComponentMonitor delegate)
Creates a AbstractComponentMonitor with a given delegate |
Method Summary | ||

void |
changeMonitor(ComponentMonitor monitor)
If the delegate supports a monitor strategy ,
this is used to changed the monitor while keeping the same delegate. |
