NaryGenerator

NaryGenerator is a composite generator that has one or more subjects. The NaryGenerator allows its subjects to be treated in the same way as a single instance of a Generator following the Composite Design Pattern.

Generator

Notation

g: A NaryGenerator.
G: A NaryGenerator type.

Valid Expressions

In addition to the requirements defined in Generator, for any NaryGenerator the following must be met:

Expression	Semantics	Return type
`g.elements`	The tuple of elements.	A Boost.Fusion Sequence of `Generator` types.

Type Expressions

Expression	Description
`g.elements_type`	Elements tuple type.
`traits::is_nary_generator<G>::type`	Metafunction that evaluates to `mpl::true_` if a certain type, `G` is a NaryGenerator, `mpl::false_` otherwise (See MPL Boolean Constant).

Invariants

For each element, E, in any NaryGenerator, G, the following invariant always holds:

traits::is_generator<E>::type evaluates to mpl::true_

Models

The following generators conform to this model:
