  • Method Details

    • getNoEntryValue

      public 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.
      Specified by:
      getNoEntryValue in interface TDoubleStack
      Returns:
      the value that represents null
    • push

      public void push(double val)
      Pushes the value onto the top of the stack.
      Specified by:
      push in interface TDoubleStack
      Parameters:
      val - an double value
    • pop

      public double pop()
      Removes and returns the value at the top of the stack.
      Specified by:
      pop in interface TDoubleStack
      Returns:
      an double value
    • peek

      public double peek()
      Returns the value at the top of the stack.
      Specified by:
      peek in interface TDoubleStack
      Returns:
      an double value
    • size

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

      public void clear()
      Clears the stack.
      Specified by:
      clear in interface TDoubleStack
    • toArray

      public double[] 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 TDoubleStack
      Returns:
      an double[] value
    • toArray

      public 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. 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 TDoubleStack
      Parameters:
      dest - the array to copy into.
    • toString
