                                 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

copyPrepareInterStageImpl

protected void copyPrepareInterStageImpl(PrepareInterStagePropsContainer copyIntoInterStagePropsContainer,
                                         PrepareInterStagePropsContainer copyFromInterStagePropsContainer)

Overrides:

copyPrepareInterStageImpl in class SpecGeneratedComponent

protected void onLoadStyle(ComponentContext c)

Overrides:

onLoadStyle in class Component

onPrepare

protected void onPrepare(ComponentContext c)

Overrides:

onPrepare in class SpecGeneratedComponent

                         Size size,
                         InterStagePropsContainer _5)

Overrides:

onMeasure in class SpecGeneratedComponent

canMeasure

protected boolean canMeasure()

Description copied from class: Component

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

Overrides:

canMeasure in class Component

onMount

protected void onMount(ComponentContext c,
                       java.lang.Object progressBar,
                       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:

c - The ComponentContext to mount the component into.

onUnmount

protected void onUnmount(ComponentContext c,
                         java.lang.Object progressBar,
                         InterStagePropsContainer _2)

Description copied from class: SpecGeneratedComponent

Unload UI elements associated with this component.

Overrides:

onUnmount in class SpecGeneratedComponent

Parameters:

c - The Context for this mount operation.

progressBar - The Drawable or View mounted by this component.

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.

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

public static Progress.Builder create(ComponentContext context)

create

public static Progress.Builder create(ComponentContext context,
                                      int defStyleAttr,
