65 * @short A value based class that hands out QNetworkAccessManager
66 * appropriately for variable bindings.
67 *
68 * NetworkAccessDelegator is an indirection mechanism which takes care of
69 * the fact that QIODevice instances are injected into the data model by
70 * having them represented using a URI. managerFor() returns appropriately
71 * the right network access manager depending on whether the URI refers to
72 * a variable, or to something else.
73 *
74 * The constructor take a pointer to two NetworkAccessDelegator instances.
75 * First is a generic one, the second is the one which handles variable
76 * bindings. managerFor() then returns the appropriate one depending on the
77 * URI.
