Constructor Detail

Link

public Link(Node source,
            Node target,
            java.lang.Object label)

Creates a link between the specified nodes with the specified label. Note that although source and target nodes are distinguished, this is not intended to imply that the link is directed. Arrows should be used to represent directed links.

Parameters:

source - a node to be connected

target - the other node to be connected.

label - the data object labeling this node.

Link

public Link(Node source,
            Node target)

Calls Link(source, target, "")

Parameters:

source - a node to be connected

target - the other node to be connected.

Method Detail

getLabel

public java.lang.Object getLabel()

Gets the data label of this link

Returns:

the data label

setLabel

public void setLabel(java.lang.Object data)

Sets the data label of this link.

Parameters:

data - the new label of this link

getSourceNode

public Node getSourceNode()

Gets the source node of this link. For non-arrow links, this should not be construed as implying a link direction.

Returns:

the source node of this link

getTargetNode

public Node getTargetNode()

Gets the target node of this link. For non-arrow links, this should not be construed as implying a link direction.

Returns:

the target node of this link
