      • getNoEntryValue

        double 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.
        Returns:
        the value that represents null
      • push

        void push​(double val)
        Pushes the value onto the top of the stack.
        Parameters:
        val - an double value
      • pop

        double pop()
        Removes and returns the value at the top of the stack.
        Returns:
        an double value
      • peek

        double peek()
        Returns the value at the top of the stack.
        Returns:
        an double value
      • size

        int size()
        Returns the current depth of the stack.
      • clear

        void clear()
        Clears the stack.
      • toArray

        double[] toArray()
        Copies the contents of the stack into a native array. Note that this will NOT pop them out of the stack.
        Returns:
        an double[] value
      • toArray

        void toArray​(double[] dest)
        Copies a slice of the list into a native array. Note that this will NOT pop them out of the stack.
        Parameters:
        dest - the array to copy into.
