  • Method Details

    • getNoEntryValue

      double getNoEntryValue()
      Returns the value that is used to represent null. The default value is generally zero, but can be configured 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.
