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

getEventDispatcher

override fun ~~getEventDispatcher~~(): EventDispatcher

getHandle

@Nullable

fun getHandle(): Handle?

getMountType

open fun getMountType(): Component.MountType

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

getPoolableContentType

open override fun getPoolableContentType(): Class<*>

getSimpleName

override fun getSimpleName(): String

getTypeId

fun getTypeId(): Int

hasClickHandlerSet

fun hasClickHandlerSet(): Boolean

hashCode

override fun hashCode(): Int

isEquivalentProps

open override fun isEquivalentProps(other: Component?, shouldCompareCommonProps: Boolean): Boolean

Determine if this component has equivalent props to a given component. This method does not compare common props.

isEquivalentTo

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

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

open override 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(): MountItemsPool.ItemPool

poolSize

open override fun poolSize(): Int

recordEventTrigger

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

resolve

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

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