      • T1

        The target type of the cast.

      • T2

        The type of the object to cast.

      Parameters

      Returns T1

    • Determines whether the specified object is equal to the current object.

      Parameters

      • obj: any

        The object to compare with the current object.

      Returns boolean

      true if the specified object is equal to the current object; otherwise, false.

    • Serves as the default hash function.

      Returns number

      A hash code for the current object.

    • Returns a string that represents the current object.

      Returns string

      A string that represents the current object.

    • Casts this object to the specified type. Returns null on failure.

      Type Parameters

      • T1

        The target type of the cast.

      • T2

        The type of the object to cast.

      Parameters

      Returns null | T1

    • Determines whether the specified object instances are considered equal.
