To create an instance of class vtkSignedCharArray, simply invoke its constructor as follows
obj = vtkSignedCharArray
obj
is an instance of the vtkSignedCharArray class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkSignedCharArray = obj.NewInstance ()
vtkSignedCharArray = obj.SafeDownCast (vtkObject o)
int = obj.GetDataType ()
- Copy the tuple value into a user-provided array.
signed = obj.char GetValue (vtkIdType id)
- Set the data at a particular index. Does not do range checking. Make sure
you use the method SetNumberOfValues() before inserting data.
obj.SetValue (vtkIdType id, signed char value)
- Specify the number of values for this object to hold. Does an
allocation as well as setting the MaxId ivar. Used in conjunction with
SetValue() method for fast insertion.
obj.SetNumberOfValues (vtkIdType number)
- Insert data at a specified position in the array.
obj.InsertValue (vtkIdType id, signed char f)
- Insert data at the end of the array. Return its location in the array.
vtkIdType = obj.InsertNextValue (signed char f)
- Get the address of a particular data index. Make sure data is allocated
for the number of items requested. Set MaxId according to the number of
data values requested.
signed = obj.string WritePointer (vtkIdType id, vtkIdType number)
- Get the address of a particular data index. Performs no checks
to verify that the memory has been allocated etc.
signed = obj.string GetPointer (vtkIdType id)
- This method lets the user specify data to be held by the array. The
array argument is a pointer to the data. size is the size of
the array supplied by the user. Set save to 1 to keep the class
from deleting the array when it cleans up or reallocates memory.
The class uses the actual array provided; it does not copy the data
from the suppled array.
