Detailed Description
appends one or more composite datasets with the same structure together into a single output composite dataset
vtkAppendCompositeDataLeaves is a filter that takes input composite datasets with the same structure: (1) the same number of entries and -- if any children are composites -- the same constraint holds from them; and (2) the same type of dataset at each position. It then creates an output dataset with the same structure whose leaves contain all the cells from the datasets at the corresponding leaves of the input datasets.
Currently, this filter only supports "appending" of a few types for the leaf nodes and the logic used for each supported data type is as follows:
- vtkUnstructuredGrid - appends all unstructured grids from the leaf location on all inputs into a single unstructured grid for the corresponding location in the output composite dataset. PointData and CellData arrays are extracted and appended only if they are available in all datasets.(For example, if one dataset has scalars but another does not, scalars will not be appended.)
- vtkPolyData - appends all polydatas from the leaf location on all inputs into a single polydata for the corresponding location in the output composite dataset. PointData and CellData arrays are extracted and appended only if they are available in all datasets.(For example, if one dataset has scalars but another does not, scalars will not be appended.)
- vtkImageData/vtkUniformGrid - simply passes the first non-null grid for a particular location to corresponding location in the output.
- vtkTable - simply passes the first non-null vtkTable for a particular location to the corresponding location in the output.
Other types of leaf datasets will be ignored and their positions in the output dataset will be NULL pointers.

Member Function Documentation
| static vtkAppendCompositeDataLeaves* vtkAppendCompositeDataLeaves::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkCompositeDataSetAlgorithm.
| static int vtkAppendCompositeDataLeaves::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 vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkCompositeDataSetAlgorithm.
| virtual int vtkAppendCompositeDataLeaves::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 vtkCompositeDataSetAlgorithm.
| static vtkAppendCompositeDataLeaves* vtkAppendCompositeDataLeaves::SafeDownCast | ( | vtkObjectBase * | o | ) | [static] |

| void vtkAppendCompositeDataLeaves::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 vtkCompositeDataSetAlgorithm.
| virtual void vtkAppendCompositeDataLeaves::SetAppendFieldData | ( | int | ) | [virtual] |
Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.
| virtual int vtkAppendCompositeDataLeaves::GetAppendFieldData | ( | ) | [virtual] |
Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.
| virtual void vtkAppendCompositeDataLeaves::AppendFieldDataOn | ( | ) | [virtual] |
Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.
| virtual void vtkAppendCompositeDataLeaves::AppendFieldDataOff | ( | ) | [virtual] |
Set/get whether the field data of each dataset in the composite dataset is copied to the output. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.
| virtual int vtkAppendCompositeDataLeaves::RequestDataObject | ( | vtkInformation * | , |
| vtkInformationVector ** | , | ||
| vtkInformationVector * | |||
| ) | [protected, virtual] |
Since vtkCompositeDataSet is an abstract class and we output the same types as the input, we must override the default implementation.
Reimplemented from vtkCompositeDataSetAlgorithm.
| virtual int vtkAppendCompositeDataLeaves::RequestData | ( | vtkInformation * | , |
| vtkInformationVector ** | , | ||
| vtkInformationVector * | |||
| ) | [protected, virtual] |
Iterates over the datasets and appends corresponding notes.
Reimplemented from vtkCompositeDataSetAlgorithm.
| virtual int vtkAppendCompositeDataLeaves::FillInputPortInformation | ( | int | port, |
| vtkInformation * | info | ||
| ) | [protected, virtual] |
The input is repeatable, so we override the default implementation.
Reimplemented from vtkCompositeDataSetAlgorithm.

| int | i, | ||
| int | numInputs, | ||
| vtkCompositeDataIterator * | iter, | ||
| vtkCompositeDataSet * | output | ||
| ) | [protected, virtual] |
When leaf nodes are unstructured grids, this uses a vtkAppendFilter to merge them.
| virtual void vtkAppendCompositeDataLeaves::AppendPolyData | ( | vtkInformationVector * | inputVector, |
| int | i, | ||
| int | numInputs, | ||
| vtkCompositeDataIterator * | iter, | ||
| vtkCompositeDataSet * | output | ||
| ) | [protected, virtual] |
When leaf nodes are polydata, this uses a vtkAppendPolyData to merge them.
| virtual void vtkAppendCompositeDataLeaves::AppendFieldDataArrays | ( | vtkInformationVector * | inputVector, |
| int | i, | ||
| int | numInputs, | ||
| vtkCompositeDataIterator * | iter, | ||
| vtkDataSet * | dset | ||
| ) | [protected, virtual] |
Both AppendUnstructuredGrids and AppendPolyData call AppendFieldDataArrays. If AppendFieldData is non-zero, then field data arrays from all the inputs are added to the output. If there are duplicates, the array on the first input encountered is taken.
