Constructor Details

AbstractNode

public AbstractNode()

Minimal constructor.

See Also:

• AbstractNode(String)

AbstractNode

AbstractNode(String n)

Simplified constructor

Parameters:

n - name of node

AbstractNode

AbstractNode(Node node)

Constructor to clone the component.

Parameters:

node - the component to clone.

Method Details

setName

@Nonnull
public String setName(@Nonnull
 String newName)

Sets the name of the node.

Once this node has been added to a graph, its name is managed by that graph: use TemporalConstraintGraph.renameNode(this, newName) instead of calling this method directly.

Specified by:

setName in interface Component

Specified by:

setName in class AbstractComponent

Parameters:

newName - cannot empty. If empty, it does nothing.

Returns:

the old name.

Throws:

IllegalStateException - if this node's name is already managed by a graph.

takeIn

public void takeIn(Node n)

Description copied from interface: Node

A copy by reference of node 'e' internal structure.

Specified by:

takeIn in interface Node

Parameters:

n - node to clone. If null, it does nothing.
