generateDataFlowGraph

public Pair3<String,Boolean,Set<String>> generateDataFlowGraph(dataflow dataflow,
                                                               boolean showLinkOnly,
                                                               boolean hideColumn,
                                                               List<RelationshipType> relationshipTypes,
                                                               Map<String,String> tooltipMap,
                                                               boolean includeIsolatedNodes)
                                                        throws IOException

Parameters:

includeIsolatedNodes - keep the tables and resultsets that take part in no relationship (a table a CREATE TABLE declares that nothing reads, the resultset of SELECT 1); the overload without it drops them from every graph but the ER graph (Mantis 4812). Use it with showLinkOnly = false, which keeps unlinked nodes too.

Throws:

IOException

getNodes

public List<Object> getNodes()

getRelationships

public List<relationship> getRelationships()
