Detailed Description

key that can used to request integer values from the pipeline vtkInformationIntegerRequestKey is a vtkInformationIntegerKey that can used to request integer values from upstream.

A good example of this is UPDATE_NUMBER_OF_PIECES where downstream can request that upstream provides data partitioned into a certain number of pieces. There are several components that make this work. First, the key will copy itself upstream during REQUEST_UPDATE_EXTENT. Second, after a successful execution, it will stor its value into a data object's information using a specific key defined by its data member DataKey. Third, before execution, it will check if the requested value matched the value in the data object's information. If not, it will ask the pipeline to execute.

The best way to use this class is to subclass it to set the DataKey data member. This is usually done in the subclass' constructor.
