Detailed Description

Class of a selection statement.

A select statement can either contain

a string e.g. for refining an SQL statement
a function object, which will be called back in order to refine a selection. This happens in calling sequences like the following:

bool MySelect::operator()(IValueLocator* l) { float px, py, pz; if ( l->get("PX",px) && l->get("PY",py) && l->get("PZ",pz) ) { float mom = sqrt(px*px+py*py+pz*pz); return mom > 100.0 * GeV; } return false; }

if "true" is returned, the object will be loaded completely.
