open override fun createContent(context: Context): Any

createMountContent

fun createMountContent(c: Context): Any

dispatchOnEvent

@Nullable

override fun dispatchOnEvent(eventHandler: EventHandler<Any>, eventState: Any): Any?

equals

operator override fun equals(@Nullable other: Any?): Boolean

getBuilderContextName

@Nullable

fun getBuilderContextName(): String?

getCommonProps

@Nullable

fun getCommonProps(): CommonProps?

getDebugAttribute

open fun <T : Any> getDebugAttribute(attributeKey: AttributeKey<T>): T & Any

getDebugAttributes

open fun getDebugAttributes(): MutableMap<AttributeKey<*>, Any>

getEventDispatcher

override fun ~~getEventDispatcher~~(): EventDispatcher

getFullyQualifiedName

fun getFullyQualifiedName(): String

getHandle

@Nullable

fun getHandle(): Handle?

getInstanceId

fun getInstanceId(): Int

getMountType

open fun getMountType(): Component.MountType

This indicates the type of the Object that will be returned by mount.

getPoolKey

open override fun getPoolKey(): Any

getSimpleName

override fun getSimpleName(): String

getTypeId

fun getTypeId(): Int

hasClickHandlerSet

fun hasClickHandlerSet(): Boolean

hasCustomDynamicProps

fun Component.hasCustomDynamicProps(): Boolean

hashCode

override fun hashCode(): Int

isEquivalentTo

override fun isEquivalentTo(@Nullable other: Component?): Boolean

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

fun isEquivalentTo(@Nullable other: Component?, shouldCompareCommonProps: Boolean): Boolean

makeShallowCopy

open fun makeShallowCopy(): Component

measure

fun measure(c: ComponentContext, widthSpec: Int, heightSpec: Int, outputSize: Size)

Measure a component with the given SizeSpec constrain.

fun measure(c: ComponentContext, widthSpec: Int, heightSpec: Int, outputSize: Size, shouldCacheResult: Boolean)

measureMightNotCacheInternalNode

fun ~~measureMightNotCacheInternalNode~~(c: ComponentContext, widthSpec: Int, heightSpec: Int, outputSize: Size)

Should not be used! Components should be manually measured only as part of a LayoutState calculation. This will measure a component and set the size in the outputSize object but the measurement result will not be cached and reused for future measurements of this component.

onCreateMountContentPool

open override fun onCreateMountContentPool(poolSizeOverride: Int): MountContentPools.ContentPool

poolSize

open override fun poolSize(): Int

recordEventTrigger

open override fun recordEventTrigger(c: ComponentContext, container: EventTriggersContainer)

recycleContent

open fun recycleContent(context: Context, content: Any, poolScope: PoolScope)

resolve

open override fun resolve(resolveContext: ResolveContext, scopedComponentInfo: ScopedComponentInfo, parentWidthSpec: Int, parentHeightSpec: Int): ComponentResolveResult

Invokes the Component-specific resolve implementation, returning a ComponentResolveResult. The ComponentResolveResult will have the LithoNode and CommonProps for the resolved component.

resolveDeferred

open override fun resolveDeferred(calculationContext: CalculationContext, componentContext: ComponentContext, parentContext: ComponentContext): ComponentResolveResult

Returns the component's resolve result for a deferred resolution. The framework invokes this instead of the resolve if the component needs to defer its resolution until layout.

resolveDeferred

fun Component.resolveDeferred(calculationContext: CalculationContext, componentContext: ComponentContext, parentContext: ComponentContext, commonProps: CommonProps?): ComponentResolveResult

setBuilderContextName

fun setBuilderContextName(@Nullable name: String?)

setDebugAttributeKey
