Signals inherited from QObject
void	destroyed (QObject *=nullptr)
	This signal is emitted immediately before the object obj is destroyed, after any instances of QPointer have been notified, and cannot be blocked.

Detailed Description

Sets up a QmlLanguageServer.

This class sets up a QML language server.

Use the following function to send replies:

std::function<void(const QByteArray &)> sendData

And, feed the data that the function receives to the {server()->receive()} method.

Call this method only from a single thread, and do not block. To achieve this, avoid direct calls, and connect the method as a slot, while reading from another thread.

The various tasks of the language server are divided between QLanguageServerModule instances. Each instance is responsible for handling a certain subset of client requests. For example, one instance handles completion requests, another one updates the code in the code model when the client sends a new file version, and so on. The QLanguageServerModule instances are constructed and registered with QLanguageServer in the constructor of this class.

Generally, do all operations in the object thread and always call handlers from it. However, the operations can delegate the response to another thread, as the response handler is thread safe. All the methods of the server() object are also thread safe.

The code model starts other threads to update its state. See its documentation for more information.
