Class AbstractScriptComponent

java.lang.Object
  org.mule.components.script.AbstractScriptComponent

All Implemented Interfaces:

org.mule.umo.lifecycle.Callable, org.mule.umo.lifecycle.Disposable, org.mule.util.monitor.FileListener, org.mule.umo.lifecycle.Initialisable, org.mule.umo.lifecycle.Lifecycle, org.mule.umo.lifecycle.Startable, org.mule.umo.lifecycle.Stoppable, org.mule.impl.UMODescriptorAware, org.mule.umo.lifecycle.UMOEventListener

public abstract class AbstractScriptComponent

extends Object

implements org.mule.umo.lifecycle.Initialisable, org.mule.umo.lifecycle.Lifecycle, org.mule.impl.UMODescriptorAware, org.mule.util.monitor.FileListener, org.mule.umo.lifecycle.Callable

AbstractScriptComponent is a component that can execute scripts as components in Mule. This component also supports reloading if the script file changes (providing the file is on the file system)
