// .NAME vtkInformation - Store vtkAlgorithm input/output information.
// .SECTION Description
// vtkInformation represents information and/or data for one input or
// one output of a vtkAlgorithm.  It maps from keys to values of
// several data types.  Instances of this class are collected in
// vtkInformationVector instances and passed to
// vtkAlgorithm::ProcessRequest calls.  The information and
// data referenced by the instance on a particular input or output
// define the request made to the vtkAlgorithm instance.

// If being "compiled" by gccxml, pretend VTKCOMMONCORE_EXPORT is nothing
// for this header file. The per-method usage of VTKCOMMONCORE_EXPORT in
// this header file leads to gccxml errors without this workaround.
