Functions

createMountContent

fun createMountContent(c: Context): Any

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

getBuilderContextName

fun getBuilderContextName(): String?

getDebugAttribute

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

getDebugAttributes

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

fun getHandle(): Handle?

open fun getMountType(): Component.MountType

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

open fun getSimpleName(): String

fun getTypeId(): Int

override fun hashCode(): Int

isEquivalentProps

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

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

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

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

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

makeShallowCopy

open fun makeShallowCopy(): Component

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.

setBuilderContextName

fun setBuilderContextName(@Nullable name: String?)

setDebugAttributeKey

open override fun <T : Any> setDebugAttributeKey(attributeKey: AttributeKey<T>, value: T & Any)

override fun toString(): String
