  • Method Details

    • getNoEntryValue

      public long 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 TLongStack
      Returns:
      the value that represents null
    • push

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

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

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

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

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

      public long[] 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 TLongStack
      Returns:
      an long[] value
    • toArray

      public void toArray(long[] 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 TLongStack
      Parameters:
      dest - the array to copy into.
