    • Method Detail

      • getNoEntryValue

        public short getNoEntryValue()
        Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.
        Specified by:
        getNoEntryValue in interface TShortStack
        Returns:
        the value that represents null

      • push

        public void push​(short val)
        Pushes the value onto the top of the stack.
        Specified by:
        push in interface TShortStack
        Parameters:
        val - an short value

      • pop

        public short pop()
        Removes and returns the value at the top of the stack.
        Specified by:
        pop in interface TShortStack
        Returns:
        an short value

      • peek

        public short peek()
        Returns the value at the top of the stack.
        Specified by:
        peek in interface TShortStack
        Returns:
        an short value

      • size

        public int size()
        Returns the current depth of the stack.
        Specified by:
        size in interface TShortStack

      • clear

        public void clear()
        Clears the stack.
        Specified by:
        clear in interface TShortStack

      • toArray

        public short[] toArray()
        Copies the contents of the stack into a native array. Note that this will NOT pop them out of the stack. The front of the list will be the top of the stack.
        Specified by:
        toArray in interface TShortStack
        Returns:
        an short[] value

      • toArray

        public void toArray​(short[] dest)
        Copies a slice of the list into a native array. Note that this will NOT pop them out of the stack. The front of the list will be the top of the stack.

        If the native array is smaller than the stack depth, the native array will be filled with the elements from the top of the array until it is full and exclude the remainder.

        Specified by:
        toArray in interface TShortStack
        Parameters:
        dest - the array to copy into.
