Method Detail

canResolve

protected boolean canResolve()

Description copied from class: Component

Indicate that this component implements its own #resolve(LayoutStateContext, ComponentContext) logic instead of going through #render(ComponentContext).

create

public static Wrapper.Builder create(ComponentContext context)

create

public static Wrapper.Builder create(ComponentContext context,
                                     int defStyleAttr,
                                     int defStyleRes)

onCreateLayout

protected Component onCreateLayout(ComponentContext c)

Description copied from class: SpecGeneratedComponent

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

Overrides:

onCreateLayout in class SpecGeneratedComponent

Parameters:

c - The ComponentContext to build a ComponentLayout tree.

resolve

protected LithoNode resolve(RenderStateContext renderStateContext,
                            ComponentContext c)

Description copied from class: Component

Resolves the ComponentLayout for the given Component.

Overrides:

resolve in class Component

isEquivalentProps

public boolean isEquivalentProps(Component other,
                                 boolean shouldCompareCommonProps)

Description copied from class: Component

Determine if this component has equivalent props to a given component. This method does not compare common props.

Overrides:

isEquivalentProps in class Component

Parameters:

other - the component to compare to

Returns:

true if the components have equivalent props

getSimpleNameDelegate

protected Component getSimpleNameDelegate()

Overrides:

getSimpleNameDelegate in class SpecGeneratedComponent

Returns:

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