vtkCollectGraph

Section: Visualization Toolkit Parallel Classes

# Usage

This filter has code to collect a graph from across processes onto vertex 0. Collection can be turned on or off using the "PassThrough" flag.

To create an instance of class vtkCollectGraph, simply invoke its constructor as follows

      obj = vtkCollectGraph

# Methods

The class vtkCollectGraph has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkCollectGraph class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkCollectGraph = obj.NewInstance ()`
- `vtkCollectGraph = obj.SafeDownCast (vtkObject o)`
- `obj.SetController (vtkMultiProcessController )` - By defualt this filter uses the global controller, but this method can be used to set another instead.
- `vtkMultiProcessController = obj.GetController ()` - By defualt this filter uses the global controller, but this method can be used to set another instead.
- `obj.SetSocketController (vtkSocketController )` - When this filter is being used in client-server mode, this is the controller used to communicate between client and server. Client should not set the other controller.
- `vtkSocketController = obj.GetSocketController ()` - When this filter is being used in client-server mode, this is the controller used to communicate between client and server. Client should not set the other controller.
- `obj.SetPassThrough (int )` - To collect or just copy input to output. Off (collect) by default.
- `int = obj.GetPassThrough ()` - To collect or just copy input to output. Off (collect) by default.
- `obj.PassThroughOn ()` - To collect or just copy input to output. Off (collect) by default.
- `obj.PassThroughOff ()` - To collect or just copy input to output. Off (collect) by default.
- `obj.SetOutputType (int )` - Directedness flag, used to signal whether the output graph is directed or undirected. DIRECTED_OUTPUT expects that this filter is generating a directed graph. UNDIRECTED_OUTPUT expects that this filter is generating an undirected graph. DIRECTED_OUTPUT and UNDIRECTED_OUTPUT flags should only be set on the client filter. Server filters should be set to USE_INPUT_TYPE since they have valid input and the directedness is determined from the input type.
- `int = obj.GetOutputType ()` - Directedness flag, used to signal whether the output graph is directed or undirected. DIRECTED_OUTPUT expects that this filter is generating a directed graph. UNDIRECTED_OUTPUT expects that this filter is generating an undirected graph. DIRECTED_OUTPUT and UNDIRECTED_OUTPUT flags should only be set on the client filter. Server filters should be set to USE_INPUT_TYPE since they have valid input and the directedness is determined from the input type.
