getFeature

public <T> T getFeature(java.lang.Class<T> role)

To acces internal optional features or plugable extensions, application asks the monitor for the extension plublic API class. The returned object implements the requested class.

The monitor is expected to "do its best" to return the expected feature, including register new features on-demand. To check for a feature to be supported, use Monitor.isFeatureSupported(java.lang.Class).

Add the ability to automagically register new features on-demand using factories provided by the FeatureManager

Specified by:

getFeature in interface Monitor

Overrides:

getFeature in class AbstractMonitor

Returns:

null if the monitor doesn't support the requested API

Monitor.getFeature(java.lang.Class)

onMonitorTaggedEvent

protected void onMonitorTaggedEvent(java.lang.String tag)
