Usage
vtkMapArrayValues allows you to associate certain values of
an attribute array (on either a vertex, edge, point, or
cell) with different values in a newly created attribute
array.
vtkMapArrayValues manages an internal STL map of vtkVariants
that can be added to or cleared. When this filter executes,
each "key" is searched for in the input array and the
indices of the output array at which there were matches the
set to the mapped "value".
You can control whether the input array values are passed to
the output before the mapping occurs (using PassArray) or,
if not, what value to set the unmapped indices to (using
FillValue).
One application of this filter is to help address the dirty
data problem. For example, using vtkMapArrayValues you could
associate the vertex values "Foo, John", "Foo, John.", and
"John Foo" with a single entity.
To create an instance of class vtkMapArrayValues, simply
invoke its constructor as follows
obj = vtkMapArrayValues
Methods
The class vtkMapArrayValues has several methods that can be
used. They are listed below. Note that the documentation is
translated automatically from the VTK sources, and may not
be completely intelligible. When in doubt, consult the VTK
website. In the methods listed below, obj is an instance of
the vtkMapArrayValues class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkMapArrayValues = obj.NewInstance ()
* vtkMapArrayValues = obj.SafeDownCast (vtkObject o)
* obj.SetFieldType (int ) - Set/Get where the data is
located that is being mapped. See FieldType enumeration
for possible values. Default is POINT_DATA.
* int = obj.GetFieldType () - Set/Get where the data is
located that is being mapped. See FieldType enumeration
for possible values. Default is POINT_DATA.
* obj.SetPassArray (int ) - Set/Get whether to copy the data
from the input array to the output array before the
mapping occurs. If turned off, FillValue is used to
initialize any unmapped array indices. Default is off.
* int = obj.GetPassArray () - Set/Get whether to copy the
data from the input array to the output array before the
mapping occurs. If turned off, FillValue is used to
initialize any unmapped array indices. Default is off.
* obj.PassArrayOn () - Set/Get whether to copy the data from
the input array to the output array before the mapping
occurs. If turned off, FillValue is used to initialize any
unmapped array indices. Default is off.
* obj.PassArrayOff () - Set/Get whether to copy the data
from the input array to the output array before the
mapping occurs. If turned off, FillValue is used to
initialize any unmapped array indices. Default is off.
* obj.SetFillValue (double ) - Set/Get whether to copy the
data from the input array to the output array before the
mapping occurs. If turned off, FillValue is used to
initialize any unmapped array indices. Default is -1.
* double = obj.GetFillValue () - Set/Get whether to copy the
data from the input array to the output array before the
mapping occurs. If turned off, FillValue is used to
initialize any unmapped array indices. Default is -1.
* obj.SetInputArrayName (string ) - Set/Get the name of the
input array. This must be set prior to execution.
* string = obj.GetInputArrayName () - Set/Get the name of
the input array. This must be set prior to execution.
* obj.SetOutputArrayName (string ) - Set/Get the name of the
output array. Default is "ArrayMap".
* string = obj.GetOutputArrayName () - Set/Get the name of
the output array. Default is "ArrayMap".
* int = obj.GetOutputArrayType () - Set/Get the type of the
output array. See vtkSetGet.h for possible values. Default
is VTK_INT.
* obj.SetOutputArrayType (int ) - Set/Get the type of the
output array. See vtkSetGet.h for possible values. Default
is VTK_INT.
* obj.AddToMap (int from, int to) - Add to the internal STL
map. "from" should be a value in the input array and "to"
should be the new value it gets assigned in the output
array.
* obj.AddToMap (int from, string to) - Add to the internal
STL map. "from" should be a value in the input array and
"to" should be the new value it gets assigned in the
output array.
* obj.AddToMap (string from, int to) - Add to the internal
STL map. "from" should be a value in the input array and
"to" should be the new value it gets assigned in the
output array.
* obj.AddToMap (string from, string to) - Add to the
internal STL map. "from" should be a value in the input
array and "to" should be the new value it gets assigned in
the output array.
* obj.ClearMap () - Clear the internal map.
* int = obj.GetMapSize () - Get the size of the internal
map.
