Class ViewCompatComponent<V extends View>

java.lang.Object

com.facebook.litho.ComponentLifecycle

com.facebook.litho.Component

com.facebook.litho.ViewCompatComponent<V>

All Implemented Interfaces:

Equivalence<Component>, EventDispatcher, EventTriggerTarget, HasEventDispatcher, HasEventTrigger, Cloneable

Deprecated.

ViewCompatComponent is not efficient as it will do measurement of views twice. Recommended way now is to use either ViewRenderInfo (which utilizes same interfaces as this class: ViewCreator and ViewBinder) if the view is used with sections API or create a custom MountSpec.

@Deprecated
public class ViewCompatComponent<V extends View>
extends Component

A component that can wrap a view using a ViewBinder class to bind the view and a ViewCreator to create the mount contents. This component will have a different recycle pool per ViewCreator instance.

Method Detail

get

public static <V extends View> ViewCompatComponent<V> get(ViewCreator<V> viewCreator,
                                                          String componentName)

Deprecated.

create

public ViewCompatComponent.Builder<V> create(ComponentContext componentContext)

Deprecated.

isEquivalentTo

public boolean isEquivalentTo(Component other)

Deprecated.

Description copied from class: Component

Compares this component to a different one to check if they are the same

This is used to be able to skip rendering a component again. We avoid using the Object.equals(Object) so we can optimize the code better over time since we don't have to adhere to the contract required for a equals method.

Specified by:

isEquivalentTo in interface Equivalence<Component>

Overrides:

isEquivalentTo in class Component

Parameters:

other - the component to compare to

Returns:

true if the components are of the same type and have the same props

canMeasure

protected boolean canMeasure()

Deprecated.

Description copied from class: ComponentLifecycle

Whether this ComponentLifecycle is able to measure itself according to specific size constraints.

Overrides:

canMeasure in class ComponentLifecycle

onMeasure

protected void onMeasure(ComponentContext c,
                         ComponentLayout layout,
                         int widthSpec,
                         int heightSpec,
                         Size size)

Deprecated.

Overrides:

onMeasure in class ComponentLifecycle

onPrepare

protected void onPrepare(ComponentContext c)

Deprecated.

Overrides:

onPrepare in class ComponentLifecycle

getMountType

public ComponentLifecycle.MountType getMountType()

Deprecated.

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

createMountContent

public V createMountContent(Context c)

Deprecated.

Overrides:

createMountContent in class ComponentLifecycle

poolSize

protected int poolSize()

Deprecated.

Overrides:

poolSize in class ComponentLifecycle
