public abstract class CookieAction
extends NodeAction

Not the preferred solution anymore, rather use Actions.context. To replace your action layer definition use more delarative way:

 <file name="action-pkg-ClassName.instance">
   <attr name="type" stringvalue="org.netbeans.api.actions.Openable"/>
   <attr name="delegate" methodvalue="org.openide.awt.Action.inject"/>
   <attr name="selectionType" stringvalue="ANY"/>
   <attr name="injectable" stringvalue="pkg.YourClass"/>
   <attr name="displayName" bundlevalue="your.pkg.Bundle#key"/>
   <attr name="iconBase" stringvalue="your/pkg/YourImage.png"/>
   <!-- if desired: <attr name="noIconInMenu" boolvalue="false"/> -->
 </file>

Constructor Detail

CookieAction

public CookieAction()

Method Detail

mode

protected abstract int mode()

Get the mode of the action: how strict it should be about cookie support.

Returns:

the mode of the action. Possible values are disjunctions of the MODE_XXX constants.

cookieClasses

protected abstract Class<?>[] cookieClasses()

Get the cookies that this action requires. The cookies are disjunctive, i.e. a node must support AT LEAST ONE of the cookies specified by this method.

Returns:

a list of cookies

enable

protected boolean enable(Node[] activatedNodes)

Test for enablement based on the cookies of selected nodes. Generally subclasses should not override this except for strange purposes, and then only calling the super method and adding a check. Just use cookieClasses() and mode() to specify the enablement logic.

Specified by:

enable in class NodeAction

Parameters:

activatedNodes - the set of activated nodes

Returns:

true to enable

createContextAwareInstance

public Action createContextAwareInstance(Lookup actionContext)

Implements ContextAwareAction interface method.

Specified by:

createContextAwareInstance in interface ContextAwareAction

Overrides:

createContextAwareInstance in class NodeAction

Parameters:

actionContext - a lookup contains action context, cannot be null

Returns:

a delegate action
