createState

public IncrementalMountExtension.IncrementalMountExtensionState createState()

Specified by:

createState in class MountExtension<IncrementalMountExtensionInput,IncrementalMountExtension.IncrementalMountExtensionState>

beforeMount

public void beforeMount(ExtensionState<IncrementalMountExtension.IncrementalMountExtensionState> extensionState,
                        IncrementalMountExtensionInput input,
                        Rect localVisibleRect)

Description copied from class: MountExtension

Called for setting up input on the extension before mounting.

Overrides:

beforeMount in class MountExtension<IncrementalMountExtensionInput,IncrementalMountExtension.IncrementalMountExtensionState>

Parameters:

extensionState - The inner state of this extension when beforeMount is called.

input - The new input the extension should use.

afterMount

public void afterMount(ExtensionState<IncrementalMountExtension.IncrementalMountExtensionState> extensionState)

Description copied from class: MountExtension

Called immediately after mounting.

Overrides:

afterMount in class MountExtension<IncrementalMountExtensionInput,IncrementalMountExtension.IncrementalMountExtensionState>

beforeMountItem

public void beforeMountItem(ExtensionState<IncrementalMountExtension.IncrementalMountExtensionState> extensionState,
                            RenderTreeNode renderTreeNode,
