Detailed Description

template<class C, class Ta, class Te>
class dueca::VarProbeElt< C, Ta, Te >

Another Template specialization of the GenericVarIO.

The VarProbeElt takes a a pointer to a member variable in that class, and this member variable must be of an array type (so elements of this thing are accessed with []). As a second argument it takes an index, and with that information and a pointer to an object of that class it can insert data directly into an element of the member. Seems dirty, but provides a really useful service. For neater IO, use the MemberCall objects, but remember that these can only put data into the object, not take it out.

Caveat: There is no bounds check, so if you supply a wrong index, you get to keep the pieces your program breaks into.

Template parameters:

Parameters

C	Class that is being probed
Ta	Type of the array, e.g. int[10]. A pointer can also be used, e.g. double*
Te	Type of the array elements, must match the first type, e.g. int.
