Classes
class	exprTypeTraits< Type >
	Simple type identifiers for polymorphic expression values. The definitions are similar to std::integral_constant in that they provide value, value_type (and name). More...
struct	exprTypeTraits< bool >
	bool expression traits More...
struct	exprTypeTraits<::Foam::label >
	label expression traits More...
struct	exprTypeTraits<::Foam::scalar >
	scalar expression traits More...
struct	exprTypeTraits<::Foam::vector >
	vector expression traits More...
struct	exprTypeTraits<::Foam::tensor >
	tensor expression traits More...
struct	exprTypeTraits<::Foam::sphericalTensor >
	sphericalTensor expression traits More...
struct	exprTypeTraits<::Foam::symmTensor >
	symmTensor expression traits More...
struct	nameOp< expressions::valueTypeCode >
	A word representation of a valueTypeCode. Empty for expressions::valueTypeCode::INVALID. More...

Namespaces
namespace	Foam::expressions
	A namespace for expression-related classes/traits etc.
namespace	Foam::expressions::Detail
	A namespace for implementation details related to expressions.
namespace	Foam
	Namespace for OpenFOAM.

Macros
#define	defineExprTypeTraits(Type, Name, Rank, NumCmpts)

Enumerations
enum class	valueTypeCode : unsigned char {   NONE = 0 , INVALID , type_bool , type_label ,   type_scalar , type_vector , type_sphericalTensor , type_symmTensor ,   type_tensor }
	An enumeration of known and expected expression value types. More...

Functions
valueTypeCode	valueTypeCodeOf (const word &dataTypeName, const expressions::valueTypeCode deflt=expressions::valueTypeCode::INVALID)
	From string to valueTypeCode (if any).
::Foam::direction	nComponents (const expressions::valueTypeCode) noexcept
	The number of components associated with given valueTypeCode.
::Foam::direction	rank (const expressions::valueTypeCode) noexcept
	The vector-space rank associated with given valueTypeCode.
word	name (const expressions::valueTypeCode typeCode)
	A word representation of a valueTypeCode. Empty for expressions::valueTypeCode::INVALID.
