Detailed Description

Labels a field as an attribute.

Date:: 2002/09/26 12:07:14

Revision:: 1.7

vtkAssignAttribute is use to label a field (vtkDataArray) as an attribute. A field name or an attribute to labeled can be specified. For example:

 aa->Assign("foo", vtkDataSetAttributes::SCALARS, 
            vtkAttributeLocation::POINT_DATA);

tells vtkAssignAttribute to make the array in the point data called "foo" the active scalars. On the other hand,

 aa->Assign(vtkDataSetAttributes::VECTORS, vtkDataSetAttributes::SCALARS, 
            vtkAttributeLocation::POINT_DATA);

tells vtkAssignAttribute to make the active vectors also the active scalars. The same can be done more easily from Tcl by using the Assign() method which takes strings:

 aa Assign "foo" SCALARS POINT_DATA 
 or
 aa Assign SCALARS VECTORS POINT_DATA

 AttributeTypes: SCALARS, VECTORS, NORMALS, TCOORDS, TENSORS
 Attribute locations: 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 Assign() 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 Assign() which takes enums.

Member Function Documentation

virtual const char* vtkAssignAttribute::GetClassName ( ) [virtual]

Reimplemented from vtkDataSetToDataSetFilter.

int vtkAssignAttribute::IsTypeOf ( const char * type ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkDataSetToDataSetFilter.

virtual int vtkAssignAttribute::IsA ( const char * type ) [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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkDataSetToDataSetFilter.

vtkAssignAttribute* vtkAssignAttribute::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkDataSetToDataSetFilter.

void vtkAssignAttribute::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 vtkDataSetToDataSetFilter.

vtkAssignAttribute* vtkAssignAttribute::New ( ) [static]

Create a new vtkAssignAttribute.
Reimplemented from vtkObject.

void vtkAssignAttribute::Assign ( int inputAttributeType,

int attributeType,

int attributeLoc

)

Label an attribute as another attribute.

void vtkAssignAttribute::Assign ( const char * fieldName,

int attributeType,

int attributeLoc

)

Label an array as an attribute.

void vtkAssignAttribute::Assign ( const char * name,

const char * attributeType,

const char * attributeLoc

)

Helper method used by other language bindings. Allows the caller to specify arguments as strings instead of enums.

void vtkAssignAttribute::Execute ( ) [protected, virtual]

This method is the old style execute method
Reimplemented from vtkSource.
