Detailed Description

read a vtkGraph from a database

Creates a vtkGraph using two SQL tables. The edge table must have one row for each edge in the graph. The table must have two columns which represent the source and target vertex ids.

The vertex table has one row for each vertex in the graph. The table must have a field whose values match those in the edge table.

The source, target, and node ID fields must be of the same type.

NOTE: This filter currently only produces the pedigree id field in the vertex attributes, and no edge attributes.

Member Function Documentation

static vtkPBGLGraphSQLReader* vtkPBGLGraphSQLReader::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkGraphAlgorithm.

static int vtkPBGLGraphSQLReader::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkGraphAlgorithm.

virtual int vtkPBGLGraphSQLReader::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkGraphAlgorithm.

static vtkPBGLGraphSQLReader* vtkPBGLGraphSQLReader::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkGraphAlgorithm.

virtual vtkObjectBase* vtkPBGLGraphSQLReader::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkGraphAlgorithm.

vtkPBGLGraphSQLReader* vtkPBGLGraphSQLReader::NewInstance ( ) const

Reimplemented from vtkGraphAlgorithm.

void vtkPBGLGraphSQLReader::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkGraphAlgorithm.

virtual void vtkPBGLGraphSQLReader::SetDirected ( bool ) [virtual]

When set, creates a directed graph, as opposed to an undirected graph.

virtual bool vtkPBGLGraphSQLReader::GetDirected ( ) [virtual]

When set, creates a directed graph, as opposed to an undirected graph.

virtual void vtkPBGLGraphSQLReader::DirectedOn ( ) [virtual]

When set, creates a directed graph, as opposed to an undirected graph.

virtual void vtkPBGLGraphSQLReader::DirectedOff ( ) [virtual]

When set, creates a directed graph, as opposed to an undirected graph.

virtual void vtkPBGLGraphSQLReader::SetDatabase ( vtkSQLDatabase * db ) [virtual]

The database to connect to.

The name of the field in the edge query for the target node of each edge.

virtual void vtkPBGLGraphSQLReader::SetVertexIdField ( const char * ) [virtual]

The name of the field in the node query for the node ID.

virtual char* vtkPBGLGraphSQLReader::GetVertexIdField ( ) [virtual]

The name of the field in the node query for the node ID.

static void vtkPBGLGraphSQLReader::GetRange	(	int	rank,
		int	total,
