Field Detail

MODE_ONE

public static final int MODE_ONE

Action will be enabled if there are one or more selected nodes and there is exactly one node which supports the given cookies.

See Also:: Constant Field Values

MODE_SOME

public static final int MODE_SOME

Action will be enabled if there are several selected nodes and some of them (at least one, but not all) support the given cookies.

See Also:: Constant Field Values

MODE_ALL

public static final int MODE_ALL

Action will be enabled if there are one or more selected nodes and all of them support the given cookies.

See Also:: Constant Field Values

MODE_EXACTLY_ONE

public static final int MODE_EXACTLY_ONE

Action will be enabled if there is exactly one selected node and it supports the given cookies.

See Also:: Constant Field Values

MODE_ANY

public static final int MODE_ANY

See Also:: Constant Field Values

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
