Detailed Description

Class for creating MPI groups.

Date:

2001/10/11 13:37:59

Revision:

1.5

This class is used to create MPI groups. A vtkMPIGroup object has to be initialized by passing the controller. Then the group can be modified by adding, removing ids and copying the contents of another group.

Member Function Documentation

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

int vtkMPIGroup::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

virtual int vtkMPIGroup::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 vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject.

vtkMPIGroup* vtkMPIGroup::New (    )  [static]

Construct a vtkMPIGroup with the following initial state: Processes = 0, MaximumNumberOfProcesses = 0. Reimplemented from vtkObject.

virtual void vtkMPIGroup::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.

void vtkMPIGroup::Initialize (  vtkMPIController *    controller )

Allocate memory for N process ids where N = controller->NumberOfProcesses

int vtkMPIGroup::AddProcessId (  int    processId )

Add a process id to the end of the list (if it is not already in the group). Returns non-zero on success. This will not add a process id >= MaximumNumberOfProcessIds.

void vtkMPIGroup::RemoveProcessId (  int    processId )

Remove the given process id from the list and shift all ids, starting from the position of the removed id, left by one.

int vtkMPIGroup::FindProcessId (  int    processId )

Find the location of a process id in the group. Returns -1 if the process id is not on the list.

int vtkMPIGroup::GetProcessId (  int    pos )

Get the process id at position pos. Returns -1 if pos >= max. available pos.

void vtkMPIGroup::CopyProcessIdsFrom (  vtkMPIGroup *    group )

Copy the process ids from a given group. This will copy N ids, where N is the smallest MaximumNumberOfProcessIds.

int vtkMPIGroup::GetNumberOfProcessIds (    )  [inline]

Returns the number of ids currently stored. Definition at line 107 of file vtkMPIGroup.h.

void vtkMPIGroup::CopyFrom (  vtkMPIGroup *    group )  [protected]

Copies all the information from group, erasing previously stored data. Similar to copy constructor

void vtkMPIGroup::Initialize (  int    numProcIds )  [protected]

Allocate memory for numProcIds process ids
