Detailed Description

A value based class that hands out QNetworkAccessManager appropriately for variable bindings.

NetworkAccessDelegator is an indirection mechanism which takes care of the fact that QIODevice instances are injected into the data model by having them represented using a URI. managerFor() returns appropriately the right network access manager depending on whether the URI refers to a variable, or to something else.

The constructor take a pointer to two NetworkAccessDelegator instances. First is a generic one, the second is the one which handles variable bindings. managerFor() then returns the appropriate one depending on the URI.
