| Method Summary | |
| public void | cancel()
| | protected void | checkWrite()
| | public void | commit()
| | final public int | compareTo(Node o)
Compares this node to the passed object.
Returns 0 if they are equal, -1 if the object passed is a NodeManager and larger than this manager,
and +1 if the object passed is a NodeManager and smaller than this manager.
This is used to sort Nodes.
A node is 'larger' than another node if its GUI() result is larger (alphabetically, case sensitive)
than that of the other node. | | public int | countRelatedNodes(NodeManager otherNodeManager, String role, String direction)

| commit | | public void commit()(Code) | | |
| compareTo | | final public int compareTo(Node o)(Code) | | Compares this node to the passed object.
Returns 0 if they are equal, -1 if the object passed is a NodeManager and larger than this manager,
and +1 if the object passed is a NodeManager and smaller than this manager.
This is used to sort Nodes.
A node is 'larger' than another node if its GUI() result is larger (alphabetically, case sensitive)
than that of the other node. If the GUI() results are the same, the nodes are compared on number,
and (if needed) on their owning clouds.
Parameters:
o - the object to compare it with 0 if they are equal, -1 if the object passed is a NodeManager and larger than this manager,and +1 if the object passed is a NodeManager and smaller than this manager. |

| delete | | public void delete(boolean deleteRelations)(Code) | | |
| deleteRelations | | final public void deleteRelations()(Code) | | |
| equals | | final public boolean equals(Object o)(Code) | | Compares two nodes, and returns true if they are equal.
This effectively means that both objects are nodes, and they both have the same number and cloud
Parameters:
o - the object to compare it with

Parameters:
value - set value |
