- - ### Field Detail

    - #### left

          public L left

      Left object

    - #### middle

          public M middle

      Middle object

    - #### right

          public R right

      Right object

  - ### Constructor Detail

    - #### MutableTriple

          public MutableTriple()

      Create a new triple instance of three nulls.

    - #### MutableTriple

          public MutableTriple(L left,
                               M middle,
                               R right)

      Create a new triple instance.
      Parameters:
        `left` - the left value, may be null
        `middle` - the middle value, may be null
        `right` - the right value, may be null

  - ### Method Detail

    - #### of

          public static <L,M,R> MutableTriple<L,M,R> of(L left,
                                                        M middle,
                                                        R right)

      Obtains a mutable triple of three objects inferring the generic types.

      This factory allows the triple to be created using inference to obtain the generic types.

      Type Parameters:
        `L` - the left element type
        `M` - the middle element type
        `R` - the right element type
      Parameters:
        `left` - the left element, may be null
        `middle` - the middle element, may be null
        `right` - the right element, may be null
      Returns:
        a triple formed from the three parameters, not null

    - #### getLeft

          public L getLeft()

      Gets the left element from this triple.

      Specified by:
        `getLeft` in class `Triple<L,M,R>`
      Returns:
        the left element, may be null

    - #### setLeft

          public void setLeft(L left)

      Sets the left element of the triple.
      Parameters:
        `left` - the new value of the left element, may be null

    - #### getMiddle

          public M getMiddle()

      Gets the middle element from this triple.

      Specified by:
        `getMiddle` in class `Triple<L,M,R>`
      Returns:
        the middle element, may be null

    - #### setMiddle

          public void setMiddle(M middle)

      Sets the middle element of the triple.
      Parameters:
        `middle` - the new value of the middle element, may be null

    - #### getRight

          public R getRight()

      Gets the right element from this triple.

      Specified by:
        `getRight` in class `Triple<L,M,R>`
      Returns:
        the right element, may be null

    - #### setRight

          public void setRight(R right)

      Sets the right element of the triple.
      Parameters:
        `right` - the new value of the right element, may be null
