object DefaultViewIdentifierResolver : ViewIdentifierResolver

Unique Identifier Generator. This class is meant for internal usage so please use it with careful as it might change in time.

Functions

resolveChildUniqueIdentifier

open override fun resolveChildUniqueIdentifier(parent: View, childName: String): Long?

Generates a persistent unique identifier for a virtual child view based on its unique name and its physical parent. The identifier will only be created once and persisted in the parent View tag to provide consistency. In case there was already a value with the same key in the tags and this was used by a different party we will try to use this value as identifier if it's a Long, in other case we will return null. This last scenario is highly unlikely but we are doing this in order to safely treat possible collisions with client tags.

Return

the unique identifier as Long or null if the identifier could not be created

Parameters

parent	the parent View of the virtual child
childName	the unique name of the virtual child

resolveViewId

open override fun resolveViewId(view: View): Long

Resolves a persistent, unique id for the given view.

Return

an identifier unquely mapping a view to a wireframe, allowing accurate diffs

Parameters

view	the view
