Detailed Description

Namespace containing type dispatching facilities.

Function Documentation

dispatch()

template<typename LIST , typename LAMBDA , typename ... Ts>

bool geos::types::dispatch	(	LIST const	combinations,
		LAMBDA &&	lambda,
		Ts &&...	objects
	)

Dispatch a generic worker function lambda based on runtime type.

Template Parameters

LIST	type of the list of types
LAMBDA	type of user-provided function or lambda, must have one auto argument
Ts	types of the objects to be dispatched.

Parameters

combinations	list of types
lambda	lambda user-provided callable
objects	objects to be dispatched

Returns

true iff type has been dispatch

todo Do we want errorIfTypeNotFound parameter? Options:

• make it a template parameter (caller always knows whether or not it wants hard errors)
• make the caller process return value and raise error if needed (and however they want)
