Function Documentation

template<class T , class A >

A localGet	(	const Eref &	er,
		string	field
	)

Similar to Field< A >::fastGet(), except that an existing Msg is not needed.

Instant-return call for a single value. Bypasses all the queueing stuff. It is hardcoded so type safety will have to be coded in too: the dynamic_cast will catch it only at runtime.

Perhaps analogous localSet(), localLookupGet(), localGetVec(), etc. should also be added.

Also, will be nice to change this to Field< A >::localGet() to make things more uniform.
