Method Detail

reset

public void reset()

Description copied from interface: NESTGraphValidator

The method resets all values stored in the validator. This method is to be used when changes have been made to the graph object after validation by the validator.

Specified by:

reset in interface NESTGraphValidator

isValidGraph

public boolean isValidGraph()

Description copied from interface: NESTGraphValidator

This method checks whether the graph is a valid nest graph. This is true if the graph has unique ids for nodes and edges and all edges are unique and connected. See methods NESTGraphValidator.hasUniqueEdgeIDs(), NESTGraphValidator.hasUniqueNodeIDs() and NESTGraphValidator.hasFullyConnectedAndNoDuplicateEdges().

Specified by:

isValidGraph in interface NESTGraphValidator

Returns:

True, if graph is valid.

hasUniqueEdgeIDs

public boolean hasUniqueEdgeIDs()

Description copied from interface: NESTGraphValidator

This method checks if all edges in the graph have unique Ids.

Specified by:

hasUniqueEdgeIDs in interface NESTGraphValidator

Returns:

True, if all edge ids are unique.

hasUniqueNodeIDs

public boolean hasUniqueNodeIDs()

Description copied from interface: NESTGraphValidator

This method checks if all nodes in the graph have unique Ids.

Specified by:

hasUniqueNodeIDs in interface NESTGraphValidator

Returns:

True, if all node ids are unique.

hasFullyConnectedAndNoDuplicateEdges

public boolean hasFullyConnectedAndNoDuplicateEdges()

Description copied from interface: NESTGraphValidator

This method checks that all edges have connections and that no edge is duplicated.

Specified by:

hasFullyConnectedAndNoDuplicateEdges in interface NESTGraphValidator

Returns:

True, if all edges are valid.

hasValidSemanticDescriptors

public boolean hasValidSemanticDescriptors()

Specified by:

hasValidSemanticDescriptors in interface NESTGraphValidator

getUniqueEdgeIDs

protected Set<String> getUniqueEdgeIDs()

getUniqueNodeIDs

protected Set<String> getUniqueNodeIDs()

getErrorMessage

public String getErrorMessage()

Description copied from interface: NESTGraphValidator

This method outputs the collected error messages from previous methods as a String.

Specified by:

getErrorMessage in interface NESTGraphValidator

Returns:

A string containing all error messages. If the string is null, the graph was valid for all previous checks.

log

protected void log(String msg)

getGraph

public NESTGraphObject getGraph()

Description copied from interface: NESTGraphValidator

This method returns the graph object for which the validator was created.

Specified by:

getGraph in interface NESTGraphValidator

Returns:

The graph object for which the validator was created.
