Classes
struct	Hessian
	Evaluation type for computing second derivatives, using HessianType as the scalar type. Only defined when built with Hessian support. More...

struct	Jacobian
	Evaluation type for computing the residual and its Jacobian, using FadType as the scalar type. More...

struct	PED
	User-defined data passed to `PHX::Evaluator::preEvaluate()`, called once before each residual/Jacobian fill. More...

struct	Residual
	Evaluation type for computing the residual only, using RealType as the scalar type. More...

struct	SD
	User-defined data passed to `PHX::Evaluator::postRegistrationSetup()` during the one-time setup phase. More...

struct	Tangent
	Evaluation type for computing directional derivatives (e.g. parameter sensitivities), using FadType as the scalar type. More...

Public Types
typedef double	RealType
	Scalar type used for the Residual evaluation type (plain double).

typedef PANZER_FADTYPE	FadType
	Sacado forward-mode AD scalar type used for the Jacobian and Tangent evaluation types.

typedef Sacado::Fad::DFad< Sacado::Fad::SFad< RealType, 1 > >	HessianType
	Nested Sacado AD scalar type (FAD-over-FAD) used for the Hessian evaluation type. Only defined when built with Hessian support.

typedef Sacado::mpl::vector< Residual, Jacobian, Tangent, Hessian >	EvalTypes
	Sacado::mpl::vector enumerating all evaluation types supported by this build (Residual, Jacobian, Tangent, and optionally Hessian).

using	SetupData = const SD &
	Data type passed to `PHX::Evaluator::postRegistrationSetup()`.

using	EvalData = const panzer::Workset &
	Data type passed to `PHX::Evaluator::evaluateFields()`: a single workset holding the cell data for one evaluation call.

using	PreEvalData = const PED &
	Data type passed to `PHX::Evaluator::preEvaluate()`.

typedef void *	PostEvalData
	Data type passed to `PHX::Evaluator::postEvaluate()`, called once after each residual/Jacobian fill. Unused by panzer (always null).

Detailed Description

Panzer's specialization of the Phalanx traits class.

This struct binds together all of the type information that the Phalanx DAG Manager and EvaluationContainer machinery needs in order to build and run field evaluators for panzer: the scalar types used for each evaluation type (residual, Jacobian, etc.), the panzer::Traits::EvalTypes mpl::vector enumerating those evaluation types, and the four user-defined data types (SetupData, EvalData, PreEvalData, PostEvalData) that Phalanx passes through to PHX::Evaluator::postRegistrationSetup(), evaluateFields(), preEvaluate(), and postEvaluate() respectively.
