Detailed Description

A subclass of QThread, which provides an event loop in a different thread.

This is created by VFS_thread, and receives configuration data passed from a config file.

Constructor & Destructor Documentation

◆ VFS_threadthread()

VFS_threadthread::VFS_threadthread	(	VFS_node *	p,
		QDomElement	nodeConfig,
		QVariantMap	env,
		bool	printConfig
	)

explicit

Parameters

p	The owning VFS_thread
nodeConfig	The XML configuration node
env	The current environment
printConfig	A debug setting, used to make sure contexts are correct

Create the VFS_threadthread, but don't run it yet. The VFS_node for this thread will not be created until VFS_threadthread::run() is called.

VFS_threadthread::~VFS_threadthread ( )

Member Function Documentation

◆ creationFailed

void VFS_threadthread::creationFailed ( )

signal

If _node creation was not possible, this signal is emitted.

Warning: Nothing is listening for this at the moment!

◆ nodeCreated

void VFS_threadthread::nodeCreated ( VFS_node * node )

signal

Once the _node has been created, this signals back to the owning VFS_thread of its existence.

◆ run()

void VFS_threadthread::run ( )

Run the QThread event loop.

The lifetime of this function is the lifetime of the thread.

VFS_creator::constructNode() is called with the config data to attempt to create the _node. If creation is successful, the _node is mount()ed and the thread blocks until the VFS_creator::outstanding semaphore has synchronized. QThread::exec() is called to start the event loop, and the method blocks until the thread completes.

If _node creation was not possible, the error is logged and creationFailed() is emitted. The event loop does not start, run() will finish, and therefore the QThread will emit finished() and trigger deletion of the VFS_thread. Semaphores are released so initialization can continue.

Note that the thread attribute is removed from the config line to prevent an infinite loop on thread creation.
