Method Detail

getNumNodes

int getNumNodes()

Gets the total number of nodes in the network.

Returns:

The total number of nodes in the network

isNode

boolean isNode(SemanticLabel label)

Returns true if the given SemanticLabel is a node in the SemanticNetwork.

Parameters:

label - The label to evaluate.

Returns:

True if the given label is a node in the network and false otherwise.

getNodes

java.util.Collection<SemanticLabel> getNodes()

Gets the nodes that are in the network.

Returns:

The collection of nodes in the network.

getOutLinks

java.util.Collection<SemanticLabel> getOutLinks(SemanticLabel nodeLabel)

Gets the outgoing links from a given node.

Parameters:

nodeLabel - The node to get the outgoing links from

Returns:

The collection of outgoing links from the given node. If the given node is not in the network, null is to be returned.

getAssociation

double getAssociation(SemanticLabel from,
                      SemanticLabel to)

Gets the association between two nodes in the network.

Parameters:

from - The node the association is from

to - The node the association is to

Returns:

The association between the given nodes
