public interface BooleanStack
extends Stack<Boolean>
A type-specific Stack; provides some additional methods that use polymorphism to avoid (un)boxing.

    • push

      @Deprecated default void push​(Boolean o)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Pushes the given object on the stack.

      This default implementation delegates to the corresponding type-specific method.

      Specified by:
      push in interface Stack<Boolean>
      Parameters:
      o - the object that will become the new top of the stack.

    • pop

      @Deprecated default Boolean pop()
      Deprecated.
      Please use the corresponding type-specific method instead.
      Pops the top off the stack.

      This default implementation delegates to the corresponding type-specific method.

      Specified by:
      pop in interface Stack<Boolean>
      Returns:
      the top of the stack.

    • top

      @Deprecated default Boolean top()
      Deprecated.
      Please use the corresponding type-specific method instead.
      Peeks at the top of the stack (optional operation).

      This default implementation returns peek(0).

      This default implementation delegates to the corresponding type-specific method.

      Specified by:
      top in interface Stack<Boolean>
      Returns:

    • peek

      @Deprecated default Boolean peek​(int i)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Peeks at an element on the stack (optional operation).

      This default implementation just throws an UnsupportedOperationException.

      This default implementation delegates to the corresponding type-specific method.

      Specified by:
      peek in interface Stack<Boolean>
      Parameters:
      i - an index from the stop of the stack (0 represents the top).
