SHARED_INSTANCE
public static final ILinkRenderer SHARED_INSTANCE
- A shared instance used as a default for any link that doesn't explicitly
override.
DefaultLinkRenderer
public DefaultLinkRenderer()
renderLink
public void renderLink(IMarkupWriter writer,
IRequestCycle cycle,
ILinkComponent linkComponent)
- Description copied from interface:
ILinkRenderer
- Renders the link, taking into account whether the link is
disabled
.
This is complicated by the fact that the rendering of the body must be done
within a nested writer, since the Link component will not render its tag
until after its body renders (to allow for any wrapped components that need
to write event handlers for the link).
The renderer is expected to call back into the link component to handle
any informal parameters, and to handle events output.
- Specified by:
renderLink
in interface ILinkRenderer
constructURL
protected String constructURL(ILink link,
String anchor,
IRequestCycle cycle)
- Converts the EngineServiceLink into a URI or URL. This implementation
simply invokes
ILink.getURL(String, boolean)
.
beforeBodyRender
protected void beforeBodyRender(IMarkupWriter writer,
IRequestCycle cycle,
ILinkComponent link)
- Invoked after the href attribute has been written but before
the body of the link is rendered (but only if the link
is not disabled).
This implementation does nothing.
afterBodyRender
protected void afterBodyRender(IMarkupWriter writer,
IRequestCycle cycle,
ILinkComponent link)
- Invoked after the body of the link is rendered, but before
ILinkComponent.renderAdditionalAttributes(IMarkupWriter, IRequestCycle)
is invoked
(but only if the link is not disabled).
This implementation does nothing.
getElement
protected String getElement()
- Since:
- 3.0
getUrlAttribute
protected String getUrlAttribute()
getHasBody
protected boolean getHasBody()
