Classes
class	panzer::Expr::EvalBase
	Base class for panzer::Expr::Eval, does everything that is independent of the Kokkos::View template parameter. More...
struct	panzer::Expr::RebindDataType< DataType, NewScalarType >
	Rebinds a Kokkos::View data type to use a new scalar type. More...
struct	panzer::Expr::RebindDataType< NestedDataType *, NewScalarType >
struct	panzer::Expr::RebindDataType< NestedDataType[], NewScalarType >
struct	panzer::Expr::RebindDataType< NestedDataType[N], NewScalarType >
struct	panzer::Expr::RebindViewType< ViewType, NewScalarType >
	Builds on RebindDataType, but acts directly on a Kokkos::View type. More...
struct	panzer::Expr::RebindViewType< Kokkos::View< DT, VP...>, NewScalarType >
class	panzer::Expr::Eval< DT, VP >
	Interprets mathematical expressions in a string and evaluates them using Kokkos::View objects as values and Kokkos::parallel_for for the operators. This class is mean to support Kokkos-parallel execution of user-provided mathematical expressions. Example uses include evaluating analytic boundary and initial conditions for a PDE problem. The API of this class (namely Eval::read_string or another read_* function inherited from Teuchos::Reader) is only meant to be called once for a given set of evaluation points. Variables should be predefined with point-dependent values all stored in a single Kokkos::View. For example, X coordinates for all points could be stored in a Kokkos::View<double*>, whose extent is the number of points. Values which are the same for all points are still supported, for example the current time. Then if the expression is for example "x^t", this class launches a single parallel_for to raise the coordinate of all points at once to the "t" power. More...
