Detailed Description

cache time steps

vtkTemporalDataSetCache cache time step requests of a temporal dataset, when cached data is requested it is returned using a shallow copy.

Member Function Documentation

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

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

Reimplemented from vtkTemporalDataSetAlgorithm.

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

Reimplemented from vtkTemporalDataSetAlgorithm.

static int vtkTemporalDataSetCache::IsTypeOf ( const char * name ) [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 vtkTemporalDataSetAlgorithm.

virtual int vtkTemporalDataSetCache::IsA ( const char * name ) [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 vtkTemporalDataSetAlgorithm.

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

Reimplemented from vtkTemporalDataSetAlgorithm.

void vtkTemporalDataSetCache::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 vtkTemporalDataSetAlgorithm.

void vtkTemporalDataSetCache::SetCacheSize ( int size )

This is the maximum number of time steps that can be retained in memory. it defaults to 10.

virtual int vtkTemporalDataSetCache::GetCacheSize ( ) [virtual]

This is the maximum number of time steps that can be retained in memory. it defaults to 10.

virtual int vtkTemporalDataSetCache::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)			`[protected, virtual]`

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkTemporalDataSetAlgorithm.
