Detailed Description

Compute connected components for a distributed vtkGraph. For directed graphs, this computes the connected components; for undirected graphs, this computes the strongly-connected components.

This VTK class uses the Parallel BGL's implementation of connected components and strongly-connectd components.

Member Function Documentation

static vtkPBGLConnectedComponents* vtkPBGLConnectedComponents::New

(

)

[static]

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

Reimplemented from vtkGraphAlgorithm.

static int vtkPBGLConnectedComponents::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 vtkPBGLConnectedComponents::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 vtkPBGLConnectedComponents* vtkPBGLConnectedComponents::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkGraphAlgorithm.

virtual vtkObjectBase* vtkPBGLConnectedComponents::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkGraphAlgorithm.

vtkPBGLConnectedComponents* vtkPBGLConnectedComponents::NewInstance

(

)

const

Reimplemented from vtkGraphAlgorithm.

void vtkPBGLConnectedComponents::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 vtkPBGLConnectedComponents::SetComponentArrayName

(

const char *

)

[virtual]

Set the name of the component number output array, which contains the component number of each vertex (a non-negative value). If no component array name is set then the name 'Component' is used.

virtual int vtkPBGLConnectedComponents::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)		[protected, virtual]

This is called by the superclass. This is the method you should override.

Reimplemented from vtkGraphAlgorithm.

virtual int vtkPBGLConnectedComponents::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)		[protected, virtual]

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkGraphAlgorithm.

virtual int vtkPBGLConnectedComponents::FillOutputPortInformation	(	int	port,
		vtkInformation *	info
	)		[protected, virtual]

Fill the output port information objects for this algorithm. This is invoked by the first call to GetOutputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkGraphAlgorithm.
