Detailed Description

scalable collective communication for a subset of members of a parallel VTK application

This class provides scalable broadcast, reduce, etc. using only a vtkMultiProcessController. It does not require MPI. Users are vtkPKdTree and vtkDistributedDataFilter.

Member Function Documentation

virtual const char* vtkSubGroup::GetClassName (   )  [virtual]
 

Reimplemented from vtkObject.

static int vtkSubGroup::IsTypeOf (  const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkSubGroup::IsA (  const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkSubGroup* vtkSubGroup::SafeDownCast (  vtkObject *  o  )  [static]
 

Reimplemented from vtkObject.

virtual void vtkSubGroup::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 vtkObject.

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

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

Reimplemented from vtkObject.

int vtkSubGroup::Initialize (  int  p0,
int  p1,
int  me,
int  tag,
vtkCommunicator *  c
) 
 

Initialize a communication subgroup for the processes with rank p0 through p1 of the given communicator. (So vtkSubGroup is limited to working with subgroups that are identified by a contiguous set of rank IDs.) The third argument is the callers rank, which must in the range from p0 through p1.
