    Interface ViewTransitionTypeSet

    The ViewTransitionTypeSet interface of the View Transition API is a set-like object representing the types of an active view transition. This enables the types to be queried or modified on-the-fly during a transition.

    Properties

    "[toStringTag]": string
    size: number

    the number of (unique) elements in Set.

    Methods

    • Appends a new element with a specified value to the end of the Set.

      Parameters

      • value: string

      Returns this

    • Removes all elements from the Set.

      Returns void

    • Removes a specified value from the Set.

      Parameters

      • value: string

      Returns boolean

      Returns true if an element in the Set existed and has been removed, or false if the element does not exist.

    • Type Parameters

      • U

      Parameters

      Returns Set<string>

      a new Set containing all the elements in this Set which are not also in the argument.

    • Returns an iterable of [v,v] pairs for every value v in the set.

      Returns SetIterator<[string, string]>

    • Parameters

      Returns void

    • Parameters

      • value: string

      Returns boolean

      a boolean indicating whether an element with the specified value exists in the Set or not.

    • Type Parameters

      • U

      Parameters

      Returns Set<string & U>

      a new Set containing all the elements which are both in this Set and in the argument.

    • Parameters

      Returns boolean

      a boolean indicating whether this Set has no elements in common with the argument.

    • Parameters

      Returns boolean

      a boolean indicating whether all the elements in this Set are also in the argument.

    • Parameters

      Returns boolean

      a boolean indicating whether all the elements in the argument are also in this Set.

    • Despite its name, returns an iterable of the values in the set.

      Returns SetIterator<string>

    • Type Parameters

      • U

      Parameters

      Returns Set<string | U>

      a new Set containing all the elements which are in either this Set or in the argument, but not in both.

    • Type Parameters

      • U

      Parameters

      Returns Set<string | U>

      a new Set containing all the elements in this Set and also all the elements in the argument.
