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.

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 vtkGraphLayoutStrategy.

virtual void vtkRandomLayoutStrategy::SetRandomSeed ( int  )
virtual

Seed the random number generator used to compute point positions.

This has a significant effect on their final positions when the layout is complete.

virtual int vtkRandomLayoutStrategy::GetRandomSeed ( )
virtual

Seed the random number generator used to compute point positions.

This has a significant effect on their final positions when the layout is complete.

virtual void vtkRandomLayoutStrategy::SetGraphBounds ( double  ,

Set / get the region in space in which to place the final graph.

The GraphBounds only affects the results if AutomaticBoundsComputation is off.

virtual void vtkRandomLayoutStrategy::SetGraphBounds ( double  [6])

Set / get the region in space in which to place the final graph.

The GraphBounds only affects the results if AutomaticBoundsComputation is off.

virtual double* vtkRandomLayoutStrategy::GetGraphBounds ( )

Set / get the region in space in which to place the final graph.

The GraphBounds only affects the results if AutomaticBoundsComputation is off.

virtual void vtkRandomLayoutStrategy::GetGraphBounds ( double  data[6])

Set / get the region in space in which to place the final graph.

The GraphBounds only affects the results if AutomaticBoundsComputation is off.

virtual void vtkRandomLayoutStrategy::SetAutomaticBoundsComputation ( vtkTypeBool  )
virtual

Turn on/off automatic graph bounds calculation.

If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual vtkTypeBool vtkRandomLayoutStrategy::GetAutomaticBoundsComputation ( )
virtual

Turn on/off automatic graph bounds calculation.

If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual void vtkRandomLayoutStrategy::AutomaticBoundsComputationOn ( )
virtual

Turn on/off automatic graph bounds calculation.

If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual void vtkRandomLayoutStrategy::AutomaticBoundsComputationOff ( )
virtual

Turn on/off automatic graph bounds calculation.

If this boolean is off, then the manually specified GraphBounds is used. If on, then the input's bounds us used as the graph bounds.

virtual void vtkRandomLayoutStrategy::SetThreeDimensionalLayout ( vtkTypeBool  )
virtual

Turn on/off layout of graph in three dimensions.

If off, graph layout occurs in two dimensions. By default, three dimensional layout is on.

virtual vtkTypeBool vtkRandomLayoutStrategy::GetThreeDimensionalLayout ( )
virtual

Turn on/off layout of graph in three dimensions.

If off, graph layout occurs in two dimensions. By default, three dimensional layout is on.

virtual void vtkRandomLayoutStrategy::ThreeDimensionalLayoutOn ( )

Turn on/off layout of graph in three dimensions.

If off, graph layout occurs in two dimensions. By default, three dimensional layout is on.

void vtkRandomLayoutStrategy::SetGraph ( vtkGraph graph)
overridevirtual

Set the graph to layout.

Reimplemented from vtkGraphLayoutStrategy.

void vtkRandomLayoutStrategy::Layout ( )
overridevirtual

Perform the random layout.

Implements vtkGraphLayoutStrategy.
