Method Detail

shouldUpdate

public boolean shouldUpdate(Component previous,
                            Component next)

Description copied from class: ComponentLifecycle

Whether the component needs updating.

For layout components, the framework will verify that none of the children of the component need updating, and that both components have the same number of children. Therefore this method just needs to determine any changes to the top-level component that would cause it to need to be updated (for example, a click handler was added).

For mount specs, the framework does nothing extra and this method alone determines whether the component is updated or not.

Overrides:

shouldUpdate in class ComponentLifecycle

Parameters:

previous - the previous component to compare against.

next - the component that is now in use.

Returns:

true if the component needs an update, false otherwise.

onCreateLayout

protected Component onCreateLayout(ComponentContext c)

Description copied from class: ComponentLifecycle

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

Overrides:

onCreateLayout in class ComponentLifecycle

Parameters:

c - The ComponentContext to build a ComponentLayout tree.

getMountType

public ComponentLifecycle.MountType getMountType()

Description copied from class: ComponentLifecycle

This indicates the type of the Object that will be returned by ComponentLifecycle.mount(com.facebook.litho.ComponentContext, java.lang.Object).

Overrides:

getMountType in class ComponentLifecycle

Returns:

one of ComponentLifecycle.MountType

onCreateTransition

public Transition onCreateTransition(ComponentContext c)

Overrides:

onCreateTransition in class ComponentLifecycle

Returns:

a TransitionSet specifying how to animate this component to its new layout and props.

create

public static TestTransitionComponent.Builder create(ComponentContext context,
                                                     int defStyleAttr,
                                                     int defStyleRes,
                                                     Component component)

create

public static TestTransitionComponent.Builder create(ComponentContext context,
                                                     Component component)

hashCode

public int hashCode()

Overrides:

hashCode in class TestComponent

equals

public boolean equals(Object o)

Overrides:

equals in class TestComponent
