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.

callsShouldUpdateOnMount

protected boolean callsShouldUpdateOnMount()

Overrides:

callsShouldUpdateOnMount in class ComponentLifecycle

isPureRender

protected boolean isPureRender()

Overrides:

isPureRender in class ComponentLifecycle

hasChildLithoViews

protected boolean hasChildLithoViews()

Description copied from class: ComponentLifecycle

Whether this ComponentLifecycle mounts views that contain component-based content that can be incrementally mounted e.g. if the mounted view has a LithoView with incremental mount enabled.

Overrides:

hasChildLithoViews in class ComponentLifecycle

onCreateMountContent

protected Object onCreateMountContent(Context c)

Description copied from class: ComponentLifecycle

Create the object that will be mounted in the LithoView.

Overrides:

onCreateMountContent in class ComponentLifecycle

Parameters:

c - The Context to be used to create the content.

Returns:

an Object that can be mounted for this component.

onMount

protected void onMount(ComponentContext c,
                       Object convertView)

Description copied from class: ComponentLifecycle

Deploy all UI elements representing the final bounds defined in the given ComponentLayout. Return either a Drawable or a View or null to be mounted.

Overrides:

onMount in class ComponentLifecycle

Parameters:

c - The ComponentContext to mount the component into.

onUnmount

protected void onUnmount(ComponentContext c,
                         Object mountedContent)

Description copied from class: ComponentLifecycle

Unload UI elements associated with this component.

Overrides:

onUnmount in class ComponentLifecycle

Parameters:

c - The Context for this mount operation.

mountedContent - The Drawable or View mounted by this component.

canMeasure

protected boolean canMeasure()

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)

Overrides:

onMeasure in class ComponentLifecycle

onBoundsDefined

protected void onBoundsDefined(ComponentContext c,
                               ComponentLayout layout)

Description copied from class: ComponentLifecycle

Called after the layout calculation is finished and the given ComponentLayout has its bounds defined. You can use ComponentLayout.getX(), ComponentLayout.getY(), ComponentLayout.getWidth(), and ComponentLayout.getHeight() to get the size and position of the component in the layout tree.

Overrides:

onBoundsDefined in class ComponentLifecycle

Parameters:

c - The Context used by this component.

layout - The ComponentLayout with defined position and size.

onBind

protected void onBind(ComponentContext c,
                      Object mountedContent)

Overrides:

onBind in class ComponentLifecycle

onUnbind

protected void onUnbind(ComponentContext c,
                        Object mountedContent)

Overrides:

onUnbind in class ComponentLifecycle

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
