Method Detail

findMountContentById

public Object findMountContentById(long id)

needsRemount

public boolean needsRemount()

True if we have manually unmounted content (e.g. via unmountAllItems) which means that while we may not have a new RenderTree, the mounted content does not match what the viewport for the LithoView may be.

Specified by:

needsRemount in interface MountDelegate.MountDelegateTarget

notifyMount

                        RenderTreeNode renderTreeNode,
                        int position)

Specified by:

notifyMount in interface MountDelegate.MountDelegateTarget

notifyUnmount

public void notifyUnmount(int position)

Specified by:

notifyUnmount in interface MountDelegate.MountDelegateTarget

mount

public void mount(RenderTree renderTree)

Mount the layoutState on the pre-set HostView.

Specified by:

mount in interface MountDelegate.MountDelegateTarget

Parameters:

renderTree - a new RenderTree to mount

Specified by:

unmountAllItems in interface MountDelegate.MountDelegateTarget

isRootItem

setUnmountDelegateExtension

public void setUnmountDelegateExtension(UnmountDelegateExtension unmountDelegateExtension)

Specified by:

attach

public void attach()

This is called when the MountItems mounted on this MountState need to be re-bound with the same RenderUnit. This happens when a detach/attach happens on the root Host that owns the MountState.

Specified by:

attach in interface MountDelegate.MountDelegateTarget

detach

public void detach()

Unbinds all the MountItems currently mounted on this MountState.

Specified by:

detach in interface MountDelegate.MountDelegateTarget

unbindMountItem

public void unbindMountItem(MountItem mountItem)

Specified by:

unbindMountItem in interface MountDelegate.MountDelegateTarget
