Constructor Detail

### SubListSpace

    public SubListSpace()

  Constructs a sub-list list.

### SubListSpace

    public SubListSpace(CoordinateDiscrete extent)

  Constructs a sub-list list.

  Parameters:
    `extent` - a coordinate describing the size of this space

Method Detail

### populate

    public void populate()

  Populates the space and its super list with clones of the prototype agent. First removes any currently existing members from the super list to prevent orphans. Prototype agent should be set before calling this method. (By default, the prototpye agent is a Node.)

  Specified by:
    `populate` in interface `Space`
  Overrides:
    `populate` in class `ListBase`

### remove

    public boolean remove(java.lang.Object o)

  Removes the supplied object (agent) from this list and its superlist. If the agent is _not_ a member of this space, but is a member of the super space, it is not removed from the super space.

  Specified by:
    `remove` in interface `java.util.Collection`
  Specified by:
    `remove` in interface `java.util.List`
  Specified by:
    `remove` in interface `Mutable`
  Overrides:
    `remove` in class `ListBase`
  Parameters:
    `o` - the agent to be removed
  Returns:
    true if the agent was deleted, false otherwise

### addAll

    public boolean addAll(int index,
                          java.util.Collection c)

  Inserts all of the agents in the specified collection at the location specified in this list, and at the end of the super list. Assumes (but does not check) that all of the elements are instances of agent.

  Specified by:
    `addAll` in interface `java.util.List`
  Overrides:
    `addAll` in class `ListBase`
  Parameters:
    `index` - the location at which to place the agents
    `c` - collection whose agents are to be added to the space
  Returns:
    true if the space had new agents added

### addAll

    public boolean addAll(java.util.Collection c)

  Inserts all of the agents in the specified collection at the location specified in this list, and at the end of the super list. Assumes (but does not check) that all of the elements are instances of agent.

  Specified by:

  Specified by:
    `addAll` in interface `java.util.List`
  Overrides:
    `addAll` in class `CollectionSpace`
  Parameters:
    `c` - collection whose agents are to be added to the space
  Returns:
    true if the space had new agents added

### removeAll

    public boolean removeAll(java.util.Collection c)

  Removes all of the agnets contained in the collection from this space list and its super space list. No attempt is made to cache the removal; the agents are all removed at once.

  Specified by:
    `removeAll` in interface `java.util.Collection`
  Specified by:
    `removeAll` in interface `java.util.List`
  Overrides:
    `removeAll` in class `CollectionSpace`
  Parameters:
    `c` - collection whose agents are to be added to the space
  Returns:
    true if the space had agents (but not neccessarily all?) removed

### retainAll

    public boolean retainAll(java.util.Collection c)

  Retains only the elements in the space that are in the specified collection. Removes from the super space list those agents that are in this list but not in the specified reatined collection.

  Specified by:
    `retainAll` in interface `java.util.Collection`
  Specified by:
    `retainAll` in interface `java.util.List`
  Overrides:
    `retainAll` in class `CollectionSpace`
  Parameters:
    `c` - collection whose agents are to be retained in the space
  Returns:
    true if this space had agents removed

### clear
