Detailed Description

Move/copy fields between field data, point data and cell data.

vtkRearrangeFields is used to copy/move fields (vtkDataArrays) between data object's field data, point data and cell data. To specify which fields are copied/moved, the user adds operations. There are two types of operations: 1. the type which copies/moves an attribute's data (i.e. the field will be copied but will not be an attribute in the target), 2. the type which copies/moves fields by name. For example:

 rf->AddOperation(vtkRearrangeFields::COPY, "foo",
                  vtkRearrangeFields::DATA_OBJECT,
                  vtkRearrangeFields::POINT_DATA);

adds an operation which copies a field (data array) called foo from the data object's field data to point data. From Tcl, the same operation can be added as follows:

 rf AddOperation COPY foo DATA_OBJECT POINT_DATA

The same can be done using Python and Java bindings by passing strings as arguments.

 Operation types: COPY, MOVE
 AttributeTypes: SCALARS, VECTORS, NORMALS, TCOORDS, TENSORS
 Field data locations: DATA_OBJECT, POINT_DATA, CELL_DATA
Warning:
When using Tcl, Java, Python or Visual Basic bindings, the array name can not be one of the AttributeTypes when calling AddOperation() which takes strings as arguments. The Tcl (Java etc.) command will always assume the string corresponds to an attribute type when the argument is one of the AttributeTypes. In this situation, use the AddOperation() which takes enums.

Member Function Documentation

static int vtkRearrangeFields::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 vtkDataSetAlgorithm.

virtual int vtkRearrangeFields::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 vtkDataSetAlgorithm.

Reimplemented from vtkDataSetAlgorithm.

virtual vtkObjectBase* vtkRearrangeFields::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkDataSetAlgorithm.

Reimplemented from vtkDataSetAlgorithm.

void vtkRearrangeFields::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 vtkDataSetAlgorithm.

Create a new vtkRearrangeFields with an empty operation list.

Reimplemented from vtkDataSetAlgorithm.

int vtkRearrangeFields::AddOperation ( int  operationType,
int  attributeType,
int  fromFieldLoc,
int  toFieldLoc 
)

Add an operation which copies an attribute's field (data array) from one field data to another. Returns an operation id which can later be used to remove the operation.

int vtkRearrangeFields::AddOperation ( int  operationType,
const char *  name,
int  fromFieldLoc,
int  toFieldLoc 
)

Add an operation which copies a field (data array) from one field data to another. Returns an operation id which can later be used to remove the operation.

int vtkRearrangeFields::AddOperation ( const char *  operationType,
const char *  attributeType,
const char *  fromFieldLoc,
const char *  toFieldLoc 
)

Helper method used by other language bindings. Allows the caller to specify arguments as strings instead of enums.Returns an operation id which can later be used to remove the operation.

Remove an operation with the given id.

int vtkRearrangeFields::RemoveOperation ( int  operationType,
int  attributeType,
int  fromFieldLoc,
int  toFieldLoc 
)

Remove an operation with the given signature. See AddOperation for details.

int vtkRearrangeFields::RemoveOperation ( int  operationType,
const char *  name,
int  fromFieldLoc,
int  toFieldLoc 
)

Remove an operation with the given signature. See AddOperation for details.

int vtkRearrangeFields::RemoveOperation ( const char *  operationType,
const char *  attributeType,
const char *  fromFieldLoc,
const char *  toFieldLoc 
)

Remove an operation with the given signature. See AddOperation for details.

Remove all operations.

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.
