// This class allows access to the PBackground protocol. PBackground allows

// single background thread in the parent process. Each PBackgroundChild
|
|
// instance is tied to the thread on which it is created and must not be shared
|
|
// across threads. Each PBackgroundChild is unique and valid as long as its
|
|
// designated thread lives.
|
|
//
|
|
// Creation of PBackground is asynchronous. GetForCurrentThread() will return
|
|
// null until the sequence is complete. GetOrCreateForCurrentThread() will start
|
|
// the creation sequence and will call back via the
|
|
// nsIIPCBackgroundChildCreateCallback interface when completed. Thereafter
|
|
// (assuming success) GetForCurrentThread() will return the same actor every
|
|
// time.
|
|
//
|
|
// CloseForCurrentThread() will close the current PBackground actor. Subsequent
|
|
// calls to GetForCurrentThread will return null. CloseForCurrentThread() may
|
|
// only be called exactly once for each thread-specific actor. Currently it is
|
|
// illegal to call this before the PBackground actor has been created.
|
|
//
|
|
// The PBackgroundChild actor and all its sub-protocol actors will be
|
|
// automatically destroyed when its designated thread completes.
