Constructor Details

InlineFrame

public InlineFrame(String id,
 Class<C> c)

Constructs an inline frame that instantiates the given Page class when the content of the inline frame is requested. The instantiated Page is used to render a response to the user.

Type Parameters:

C -

Parameters:

id - See Component

c - Page class

InlineFrame

public InlineFrame(String id,
 Class<C> c,
 PageParameters params)

Constructs an inline frame that instantiates the given Page class when the content of the inline frame is requested. The instantiated Page is used to render a response to the user.

Type Parameters:

C -

Parameters:

id - See Component

c - Page class

params - Page parameters

InlineFrame

public InlineFrame(String id,
 Page page)

This constructor is ideal if a Page object was passed in from a previous Page. Construct an inline frame containing the given Page.

Parameters:

id - See component

page - The page

InlineFrame

public InlineFrame(String id,
 IPageProvider pageProvider)

This constructor is ideal for constructing pages lazily. Constructs an inline frame which invokes the getPage() method of the IPageLink interface when the content of the inline frame is requested. Whatever Page objects is returned by this method will be rendered back to the user.

Parameters:

id - See Component

pageProvider - the provider of the page to be contained in the inline frame if and when the content is requested

Method Details

getURL

protected CharSequence getURL()

Gets the url to use for this link.

Returns:

The URL that this link links to

onComponentTag

protected void onComponentTag(ComponentTag tag)

Handles this frame's tag.

Overrides:

onComponentTag in class Component

Parameters:

tag - the component tag

See Also:

• Component.onComponentTag(ComponentTag)

rendersPage

public boolean rendersPage()

Description copied from interface: IRequestListener

Does invocation of this listener render the page.

Specified by:

rendersPage in interface IRequestListener

Returns:

default true, i.e. a RenderPageRequestHandler is schedules after invocation

onRequest

public final void onRequest()

Description copied from interface: IRequestListener

Called when a request is received.

Specified by:

onRequest in interface IRequestListener

getStatelessHint

protected boolean getStatelessHint()

Description copied from class: Component

Returns whether the component can be stateless. Also the component behaviors must be stateless, otherwise the component will be treat as stateful. In order for page to be stateless (and not to be stored in session), all components (and component behaviors) must be stateless.

Overrides:

getStatelessHint in class Component

Returns:

whether the component can be stateless
