// If Tpetra is compiled with explicit instantiation,
// we have to choose data types that are compiled into Tpetra.
//
// Epetra uses (scalar/lno/gno) == (double/int/int) data types.  If we
// are using these data types, we can test Epetra user input.

// TODO:  KDD 8/13/14
// Global definitions of types gno_t, lno_t, zgid_t and
// scalar_t can cause bugs in the code.  If a class fails to define these
// types, but this file is included before the class file, the types
// from Zoltan2_TestHelpers.hpp will be used in the class.  Compilation in
// user programs (without Zoltan2_TestHelpers.hpp) would then fail.  An
// example of this bug was in the GeometricGenerator class, which used
// scalar_t without defining it.
// In this "fix," I changed gno_t, lno_t, zgid_t, scalar_t, and node_t to
// zgno_t, zlno_t, zzgid_t, zscalar_t and znode_t in Zoltan2_TestHelpers.hpp.
// This change is not the best fix; a better fix would remove the global
// definitions, but that would require more work.  (An even better change
// would use the Teuchos test framework to cycle through various options,
// but that would require even more work and should be delayed until we
// revamp the testing.)
