Method Detail

addGraphAttribute

public void addGraphAttribute(java.lang.String attr)

Interface to accept graph-level attributes that should be added to the graph's header information.

Parameters:

attr - a graph-level attribute string (e.g. size="4,4") to be added to the output

addNamespace

public void addNamespace(java.lang.String namespacePrefix,
                         java.lang.String namespaceName)

This method adds a namespace prefix and the associated namespace URI to the consumer. Instances of the fully qualified namespace URIs in all nodes are replaced with the prefix. Note: empty prefixes are supported, for example, foo.addNamespace( "", fullURI ); Will cause all instances of fullURI to be replaced by the empty string, useful for omitting the doc-source node that SiRPAC produces.

Parameters:

namespacePrefix - The prefix to associate with the fully qualified namespace URI.

namespaceName - The fully qualified namespace name.

startModel

public void startModel()

This method dumps the Graph Viz header. Put any special GraphViz commands here.

Specified by:

startModel in interface RDFConsumer

Overrides:

startModel in class DumpConsumer

endModel

public void endModel()

This method dumps out the Graph Viz footer.

Specified by:

endModel in interface RDFConsumer

Overrides:

endModel in class DumpConsumer

getNodeFactory

public NodeFactory getNodeFactory()

Description copied from interface: RDFConsumer

node factory to be used by the parser for creating resources and literals passed to addStatement

Specified by:

getNodeFactory in interface RDFConsumer

Overrides:

getNodeFactory in class DumpConsumer

addStatement

public void addStatement(Statement s)

This method outputs text to stdout that is suitable for use in GraphViz.

Specified by:

addStatement in interface RDFConsumer

Overrides:

addStatement in class DumpConsumer

Parameters:

s -

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

main method for debugging the DOT file generator Input is a URI Output (to stdout) is the input for the DOT program
