Class DefaultEventPluginImpl

java.lang.Object

org.azyva.dragom.execcontext.plugin.impl.DefaultEventPluginImpl

All Implemented Interfaces:

org.azyva.dragom.execcontext.plugin.EventPlugin, org.azyva.dragom.execcontext.plugin.ExecContextPlugin, org.azyva.dragom.execcontext.plugin.ToolLifeCycleExecContextPlugin

public class DefaultEventPluginImpl
extends Object
implements org.azyva.dragom.execcontext.plugin.EventPlugin, org.azyva.dragom.execcontext.plugin.ToolLifeCycleExecContextPlugin

Default EventPlugin implementation.

The NodeEventListener's must be registered explicitly and are kept in memory only, either in workspace or tool scope.

ToolLifeCycleExecContextPlugin is implemented so that the plugin is aware of tool end, so that the NodeEventListener's registered in tool scope can be discarded.

But NodeEventListener's are not persisted within the workspace and remain instantiated as long as the workspace is cached in memory. NodeEventListener's must be registered whenever a workspace is initialized.
