// Class : PStatClient
|
|
// Description : Manages the communications to report statistics via a
|
|
// network connection to a remote PStatServer.
|
|
//
|
|
// Normally, there is only one PStatClient in the world,
|
|
// although it is possible to have multiple PStatClients
|
|
// if extraordinary circumstances require in. Since
|
|
// each PStatCollector registers itself with the
|
|
// PStatClient when it is created, having multiple
|
|
// PStatClients requires special care when constructing
|
|
// the various PStatCollectors.
|
|
//
|
|
// If DO_PSTATS is not defined, we don't want to use
|
|
// stats at all. This class is therefore defined as a
|
|
// stub class.
