Detailed Description

abstract superclass for composite (multi-block or AMR) datasets

vtkCompositeDataSet is an abstract class that represents a collection of datasets (including other composite datasets). It provides an interface to access the datasets through iterators. vtkCompositeDataSet provides methods that are used by subclasses to store the datasets. vtkCompositeDataSet provides the datastructure for a full tree representation. Subclasses provide the semantics for it and control how this tree is built.

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 vtkDataObject.

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.

Reimplemented in vtkOverlappingAMR, vtkMultiBlockDataSet, vtkPartitionedDataSet, vtkDataObjectTree, vtkMultiPieceDataSet, vtkUniformGridAMR, vtkHierarchicalBoxDataSet, vtkPartitionedDataSetCollection, and vtkNonOverlappingAMR.

Sets the data set at the location pointed by the iterator.

The iterator does not need to be iterating over this dataset itself. It can be any composite datasite with similar structure (achieved by using CopyStructure).

Implemented in vtkUniformGridAMR, and vtkDataObjectTree.

virtual vtkDataObject* vtkCompositeDataSet::GetDataSet ( vtkCompositeDataIterator * iter )

pure virtual

Returns the dataset located at the positiong pointed by the iterator.

The iterator does not need to be iterating over this dataset itself. It can be an iterator for composite dataset with similar structure (achieved by using CopyStructure).

static

Retrieve an instance of this class from an information object.

static vtkCompositeDataSet* vtkCompositeDataSet::GetData	(	vtkInformationVector *	v,

Shallow and Deep copy.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, and vtkUniformGridAMR.

virtual vtkIdType vtkCompositeDataSet::GetNumberOfPoints ( )

virtual

Returns the total number of points of all blocks.

This will iterate over all blocks and call GetNumberOfPoints() so it might be expensive.

Reimplemented in vtkDataObjectTree.

virtual vtkIdType vtkCompositeDataSet::GetNumberOfCells ( )

virtual

Returns the total number of cells of all blocks.

This will iterate over all blocks and call GetNumberOfPoints() so it might be expensive.

Reimplemented in vtkDataObjectTree.

static vtkInformationStringKey* vtkCompositeDataSet::NAME ( )

static

Key used to put node name in the meta-data associated with a node.

static vtkInformationIntegerKey* vtkCompositeDataSet::CURRENT_PROCESS_CAN_LOAD_BLOCK ( )

static

Key used to indicate that the current process can load the data in the node.

Used for parallel readers where the nodes are assigned to the processes by the reader to indicate further down the pipeline which nodes will be on which processes. ***THIS IS AN EXPERIMENTAL KEY SUBJECT TO CHANGE WITHOUT NOTICE***
