Method Detail

defaultTagName

public java.lang.String defaultTagName()

Description copied from class: RenderableComponent

Subclasses must implement this. If no xhtml tagname can be resolved from rendering hints, will default to value returned by this method.

Specified by:

defaultTagName in class RenderableComponent

Returns:

_render

public void _render(org.xmlpull.v1.XmlSerializer serializer)
             throws java.io.IOException

Description copied from class: RenderableComponent

Default implementation. Handles render before/after logic. Will first figure out the xhtml tag to use from rendering hints, then delegates to renderComponent(). Subclasses should override renderComponent() rather than this method.

Overrides:

_render in class RenderableComponent

Throws:

java.io.IOException

id

public Block id(java.lang.String componentId)

Description copied from class: Component

Changes the componentId.

Overrides:

id in class Component

Parameters:

componentId - New component id.

Returns:

renderHint

public Block renderHint(java.lang.CharSequence renderHint)

Description copied from class: Component

Adds a rendering hint to this component. A rendering hint can be either a css class reference or a xhtml specification tag name. Many rendering hints can be given in one input string. Example: "h1 error" will cause the component to render as <h1 class="error">. Note that the html tag name doesn't have to be first.

Overrides:

renderHint in class Component

Returns:

Will return the component itself to enable method chaining.
