getScriptEngineExtensions

public List<String> getScriptEngineExtensions()

Get the list of script engine extensions

Returns:

The list of script engine extensions

handleEvent

public void handleEvent(org.osgi.service.event.Event event)

Specified by:

handleEvent in interface org.osgi.service.event.EventHandler

See Also:

• EventHandler.handleEvent(org.osgi.service.event.Event)

serviceChanged

public void serviceChanged(org.osgi.framework.ServiceEvent event)

Specified by:

serviceChanged in interface org.osgi.framework.ServiceListener

flushCache

public void flushCache()

onChange

public void onChange(List<ResourceChange> changes)

Description copied from interface: ResourceChangeListener

Report resource changes based on the filter properties of this listener.

Note that resource changes for paths which are ancestors of the paths this listener was registered to may be reported through this method. This is due to limitations of certain resource providers to provide events on a more granular level (e.g. for deletion or movement of resources containing (potentially nested) child resources).

Starting with version 1.2 of this API, an instance of ResoureChangeList is passed as the parameter to allow passing additional information.

Specified by:

onChange in interface ResourceChangeListener

Parameters:

changes - The changes list. This list is immutable.
