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:

A clone.

Throws:
