Usage
vtkLongArray is an array of values of type long. It provides
methods for insertion and retrieval of values and will
automatically resize itself to hold new data.
To create an instance of class vtkLongArray, simply invoke
its constructor as follows
obj = vtkLongArray
Methods
The class vtkLongArray 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 vtkLongArray class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkLongArray = obj.NewInstance ()
* vtkLongArray = obj.SafeDownCast (vtkObject o)
* int = obj.GetDataType () - Copy the tuple value into a
user-provided array.
* obj.GetTupleValue (vtkIdType i, long tuple) - Set the
tuple value at the ith location in the array.
* obj.SetTupleValue (vtkIdType i, long tuple) - Insert
(memory allocation performed) the tuple into the ith
location in the array.
* obj.InsertTupleValue (vtkIdType i, long tuple) - Insert
(memory allocation performed) the tuple onto the end of
the array.
* vtkIdType = obj.InsertNextTupleValue (long tuple) - Get
the data at a particular index.
* long = obj.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, long 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, long f) - Insert data at
the end of the array. Return its location in the array.
* vtkIdType = obj.InsertNextValue (long 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.
* obj.SetArray (long array, vtkIdType size, int save) - 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.
* obj.SetArray (long array, vtkIdType size, int save, int
deleteMethod)
