## CGAL::Compose<F0,F1,F2,F3>

### Definition

The class Compose<F0,F1,F2,F3> is used to specify the type of a composed functor, i.e., the functor that results from composing functors of type F1, F2, and F3, into a functor of type F0. The arguments F2 and F3 are optional, such that between two and four functors can participate in the composition. The class is used in conjunction with the compose function; see there for an explanation on how exactly the functors are combined.

### Types

Compose<F0,F1,F2,F3>::Type
| type of the composed functor.

### Notes

This class encapsulates the differences in implementation of the composers across various platforms. But in any case, Type refers to a model of AdaptableFunctor.
