Constructor Detail

### AbstractObjectList

    protected AbstractObjectList()

  Creates a new list with the default initial capacity.

### AbstractObjectList

    protected AbstractObjectList(int initialCapacity)

  Creates a new list.

  Parameters:
    `initialCapacity` - the initial capacity.

### AbstractObjectList

    protected AbstractObjectList(int initialCapacity,
                                 int increment)

  Creates a new list.

  Parameters:
    `initialCapacity` - the initial capacity.
    `increment` - the increment.

Method Detail

### get

    protected java.lang.Object get(int index)

  Returns the object at the specified index, if there is one, or `null`.

  Parameters:
    `index` - the object index.
  Returns:
    The object or `null`.

### set

    protected void set(int index,
                       java.lang.Object object)

  Sets an object reference (overwriting any existing object).

  Parameters:
    `index` - the object index.
    `object` - the object (`null` permitted).

### clear

    public void clear()

  Clears the list.

### size

    public int size()

  Returns the size of the list.

  Returns:
    The size of the list.

### indexOf

    protected int indexOf(java.lang.Object object)

  Returns the index of the specified object, or -1 if the object is not in the list.

  Parameters:
    `object` - the object.
  Returns:
    The index or -1.

### equals

    public boolean equals(java.lang.Object obj)

  Tests this list for equality with another object.

  Overrides:
    `equals` in class `java.lang.Object`
  Parameters:
    `obj` - the object to test.
  Returns:
    A boolean.

### hashCode

    public int hashCode()

  Returns a hash code value for the object.

  Overrides:
    `hashCode` in class `java.lang.Object`
  Returns:
    the hashcode

### clone

    public java.lang.Object clone()
                           throws java.lang.CloneNotSupportedException

  Clones the list of objects. The objects in the list are not cloned, so this is method makes a 'shallow' copy of the list.

  Overrides:
    `clone` in class `java.lang.Object`
  Returns:
