Method Detail

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

onCreateMountContent

protected java.lang.Object onCreateMountContent(Context c)

Description copied from class: Component

Create the object that will be mounted in the LithoView.

Overrides:

onCreateMountContent in class Component

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 context,
                       java.lang.Object cardShadowDrawable,
                       InterStagePropsContainer _2)

Description copied from class: SpecGeneratedComponent

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 SpecGeneratedComponent

Parameters:

context - The ComponentContext to mount the component into.

getMountType

public Component.MountType getMountType()

Description copied from class: Component

This indicates the type of the Object that will be returned by com.facebook.litho.Component#mount.

Overrides:

getMountType in class Component

Returns:

one of Component.MountType

poolSize

public int poolSize()

Description copied from interface: ContentAllocator

This API informs the framework about the size of the content pool. The default is 3.

Experimental. Currently for Litho team internal use only.

Specified by:

poolSize in interface ContentAllocator

Overrides:

poolSize in class SpecGeneratedComponent

canPreallocate

public boolean canPreallocate()

Description copied from interface: ContentAllocator

This API informs the framework to fill the content pool for this Mountable ahead of time. The default value is false, i.e. content is not pre-allocated. Pre-allocation of the content can improve performance in some circumstances where creating the content is expensive.

Specified by:

canPreallocate in interface ContentAllocator

Overrides:

canPreallocate in class SpecGeneratedComponent

Returns:

true if this component can be preallocated.

isPureRender

public boolean isPureRender()

Overrides:

isPureRender in class Component

create

public static CardShadow.Builder create(ComponentContext context)

create

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