Detailed Description

template<typename T>
struct openvrml::FieldValueConcept< T >

Concept checking class to validate that a template parameter is a model of the Field Value concept.

A Field Value is a concrete type that inherits field_value and holds a value for a field of a node.

Refinement of

Default Constructible, Copy Constructible, Assignable, Equality Comparable

Associated types

Value type

T::value_type

The type of T's value member. The value type must be Assignable and DefaultConstructible.

Notation

T	A type that is a model of Field Value
v	A reference of type field_value &

Definitions

Valid expressions

In addition to the expressions defined in Assignable and EqualityComparable, the following expressions must be valid.

Name	Expression	Type requirements	Return type
Downcast	static_cast<T &>(v)		T &
