template<typename T >

Message<T> Grappa::message	(	Core	dest,
		T	t
	)

inline

Construct a message allocated on the stack.

Can be used with lambdas, functors, or function pointers. Example:

// using a lambda
auto m1 = Grappa::message( destination, [] { blah(); } );
// using a functor
class Functor { ... };
auto m2 = Grappa::message( destination, Functor( args ) );
// using a function pointer (via std::bind functor)
void foo( int bar, double baz ) { blah(); }
auto m3 = Grappa::message( destination, std::bind( &foo, 1, 2.3 ) );

Parameters

dest	Core to which message will be delivered
t	Functor or function pointer that will be called on destination core

Returns: Message object
