//----------------------------------------------------------------------------
// These macros may be used to deprecate APIs in ParaView. They act as
// attributes on method declarations and do not remove methods from a build
// based on build configuration.
//
// To use:
//
// In the declaration:
//
// ```cxx
// PARAVIEW_DEPRECATED_IN_X_Y_Z("reason for the deprecation")
// void oldApi();
// ```
//
// When selecting which version to deprecate an API in, use the newest macro
// available in this header.
//
// In the implementation:
//
// ```cxx
// // Hide PARAVIEW_DEPRECATED_IN_X_Y_Z() warnings for this class.
// #define PARAVIEW_DEPRECATION_LEVEL 0
//
// #include "vtkLegacy.h"
//
// void oldApi()
// {
//   // One of:
//   VTK_LEGACY_BODY(oldApi, "ParaView X.Y.Z");
//   VTK_LEGACY_REPLACED_BODY(oldApi, "ParaView X.Y.Z", newApi);
//
//   // Remaining implementation.
// }
// ```
//
// Please note the `PARAVIEW_DEPRECATED_IN_` version in the
// `PARAVIEW_DEPRECATION_LEVEL` comment so that it can be removed when that
// version is finally removed.
//----------------------------------------------------------------------------
