Detailed Description

Receives data from another process.

Date:

Revision:
1.10

InputPort connects the pipeline in this process to one in another processes. It communicates all the pipeline protocol so that the fact you are running in multiple processes is transparent. An input port is used as a source (input to a process). One is placed at the start of a pipeline, and has a single corresponding output port in another process (specified by RemoteProcessId).

Member Function Documentation

virtual const char* vtkInputPort::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 vtkSource.

vtkMultiProcessController* vtkInputPort::GetController   [inline]
 

Access to the controller used for communication. By default, the global controller is used.

vtkPolyData* vtkInputPort::GetPolyDataOutput  
 

Note: You have to ask for the right type, and it has to match the type of the up stream port input, or you will get an error. We have to live with the fact that the error will not occur until an update is called.

virtual int vtkInputPort::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 vtkSource.

int vtkInputPort::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 vtkSource.

vtkInputPort* vtkInputPort::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkSource.

void vtkInputPort::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 vtkSource.

void vtkInputPort::PropagateUpdateExtent vtkDataObject *vtkNotUsed(output)    [inline]
 

Need to override to propagate across port.

vtkInputPort* vtkInputPort::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 vtkSource.

virtual void vtkInputPort::SetRemoteProcessId int    [virtual]
 

The matching OutputPort is specified by the output port's process and a tag. There can be more than one output port per process. THE TAG MUST BE EVEN BECAUSE TWO RMIs ARE CREATED FROM IT!!!

void vtkInputPort::TriggerAsynchronousUpdate   [virtual]
 

Need to override to trigger the update across the port

Reimplemented from vtkSource.

void vtkInputPort::UpdateData vtkDataObject   out [virtual]
 

Need to override to propagate across port

Reimplemented from vtkSource.

void vtkInputPort::UpdateInformation   [virtual]
 

Need to override to propagate across port.

Reimplemented from vtkSource.
