Method Detail

getSimpleName

public final java.lang.String getSimpleName()

Should only be used by logging to provide more readable messages.

Overrides:

getSimpleName in class Component

getSimpleNameDelegate

protected Component getSimpleNameDelegate()

Returns:

the Component this Component should delegate its getSimpleName calls to. See LayoutSpec#simpleNameDelegate()

render

protected RenderResult render(ComponentContext c,
                              int widthSpec,
                              int heightSpec)

Description copied from class: Component

Invokes the Component-specific render implementation, returning a RenderResult. The RenderResult will have the Component this Component rendered to (which will then need to be render()'ed or Component.resolve(LayoutStateContext, ComponentContext)'ed), as well as other metadata from that render call such as transitions that should be applied.

Overrides:

render in class Component

onCreateLayout

protected Component onCreateLayout(ComponentContext c)

Generate a tree of ComponentLayout representing the layout structure of the Component and its sub-components.

Parameters:

c - The ComponentContext to build a ComponentLayout tree.

onCreateLayoutWithSizeSpec

protected Component onCreateLayoutWithSizeSpec(ComponentContext c,
                                               int widthSpec,
                                               int heightSpec)

usesLocalStateContainer

protected boolean usesLocalStateContainer()

Overrides:

usesLocalStateContainer in class Component
