Method Detail

createComponentEventLink

public Link createComponentEventLink(Page page,
                                     String nestedId,
                                     String eventType,
                                     boolean forForm,
                                     Object... eventContext)

Description copied from interface: LinkSource

Creates a stateful action link. Action links are built for components. Action links are encoded by the current request (that is, bound to the current request's session, if any).

Specified by:

createComponentEventLink in interface LinkSource

Parameters:

page - the page holding the component

nestedId - the component's qualified id (a sequence of simple ids, separated by dots).

eventType - the type of event to trigger

forForm - true if the link is for a form, false otherwise

eventContext - Additional path data, each value will be converted to a string and appended to the URI @return a link

ComponentResourcesCommon.createActionLink(String, boolean, Object[])

createPageRenderLink

public Link createPageRenderLink(String pageName,
                                 boolean override,
                                 Object... pageActivationContext)

Description copied from interface: LinkSource

Creates a render link for the page. If an activation context is supplied then that context is built into the URI. If no activation context is supplied, then the activation context is obtained from the page itself, by triggering a passivate event on its root component.

When the activationContext is an empty array, the targeted page is checked to see if it can provide an activation context. This is accomplished by triggering a "passivate" event on the targeted page. If the override parameter is true, this will not occur (even when the activation context is empty).

Specified by:

createPageRenderLink in interface LinkSource

Parameters:

pageName - name of the page to which a link should be created

override - if true, then the provided activation context is always used even if empty

pageActivationContext - the activation context for the page

Returns:

a link

ComponentResourcesCommon.createPageLink(String, boolean, Object[])

getLinkCreationHub

public LinkCreationHub getLinkCreationHub()

Description copied from interface: LinkSource

Returns the hub, used to register and de-register LinkCreationListener2s.

Specified by:

getLinkCreationHub in interface LinkSource

Returns:

the hub

addListener

public void addListener(LinkCreationListener listener)

Description copied from interface: LinkCreationHub

Adds a listener. If the scope of the listener is per-thread, then it must be removed.

Specified by:

addListener in interface LinkCreationHub

addListener

public void addListener(LinkCreationListener2 listener)

Description copied from interface: LinkCreationHub

Adds a listener. If the scope of the listener is per-thread, then it must be removed.

Specified by:

addListener in interface LinkCreationHub
