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

inlinevirtual |
Get the port currently producing this object.
Copies the tree structure from the input. All pointers to non-composite data objects are intialized to NULL. This also shallow copies the meta data associated with all the nodes.
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).
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).
Returns the meta-data associated with the position pointed by the iterator. This will create a new vtkInformation object if none already exists. Use HasMetaData to avoid creating the vtkInformation object unnecessarily. 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).
Returns if any meta-data associated with the position 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).

Return the actual size of the data in kilobytes. This number is valid only after the pipeline has updated.

Returns the total number of points of all blocks. This will iterate over all blocks and call GetNumberOfPoints() so it might be expansive.
Key used to put node name in the meta-data associated with a node.

Set the number of children.

Get the number of children.

Set child dataset at a given index. The number of children is adjusted to to be greater than the index specified.
void vtkCompositeDataSet::RemoveChild |
( |

Remove the child at a given index.
Returns a child dataset at a given index.
vtkInformation* vtkCompositeDataSet::GetChildMetaData |
( |
unsigned int |
index | ) |
|
|
protected |
Returns the meta-data at a given index. If the index is valid, however, no information object is set, then a new one will created and returned. To avoid unnecessary creation, use HasMetaData().

Sets the meta-data at a given index.

index | ) |
|
|
protected |
Returns if meta-data information is available for the given child index. Returns 1 is present, 0 otherwise.
