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.

virtual int vtkCompositeDataSet::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataObject.

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

void vtkCompositeDataSet::PrintSelf ( ostream &  os,

overridevirtual

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 vtkObject.

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

virtual VTK_NEWINSTANCE vtkCompositeDataIterator* vtkCompositeDataSet::NewIterator ( )
pure virtual

Return a new iterator (the iterator has to be deleted by user).

Implemented in vtkDataObjectTree, vtkOverlappingAMR, vtkHierarchicalBoxDataSet, and vtkUniformGridAMR.

int vtkCompositeDataSet::GetDataObjectType ( )
inlineoverridevirtual

Return class name of data type (see vtkType.h for definitions).

Reimplemented from vtkDataObject.

Reimplemented in vtkMultiBlockDataSet, vtkMultiPieceDataSet, vtkOverlappingAMR, vtkHierarchicalBoxDataSet, vtkNonOverlappingAMR, and vtkUniformGridAMR.

Definition at line 66 of file vtkCompositeDataSet.h.

virtual void vtkCompositeDataSet::CopyStructure ( vtkCompositeDataSet input)
pure virtual

Copies the tree structure from the input.

All pointers to non-composite data objects are initialized to NULL. This also shallow copies the meta data associated with all the nodes.

Implemented in vtkUniformGridAMR, and vtkDataObjectTree.

virtual void vtkCompositeDataSet::SetDataSet ( vtkCompositeDataIterator iter,
vtkDataObject dataObj 
)
pure virtual

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).

Implemented in vtkUniformGridAMR, and vtkDataObjectTree.

unsigned long vtkCompositeDataSet::GetActualMemorySize ( )
overridevirtual

Return the actual size of the data in kibibytes (1024 bytes).

This number is valid only after the pipeline has updated.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree.

static vtkCompositeDataSet* vtkCompositeDataSet::GetData ( vtkInformation info)
static

Retrieve an instance of this class from an information object.

static vtkCompositeDataSet* vtkCompositeDataSet::GetData ( vtkInformationVector v,
int  i = 0 
)
static

Retrieve an instance of this class from an information object.

void vtkCompositeDataSet::Initialize ( )
overridevirtual

Restore data object to initial state,.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, and vtkUniformGridAMR.

void vtkCompositeDataSet::ShallowCopy ( vtkDataObject src)
overridevirtual

Shallow and Deep copy.

Reimplemented from vtkDataObject.

Reimplemented in vtkDataObjectTree, and vtkUniformGridAMR.

void vtkCompositeDataSet::DeepCopy ( vtkDataObject src)
overridevirtual

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 expansive.

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***
