ConnectionType

enum libcamera::ConnectionType

Connection type for asynchronous communication.

This enumeration describes the possible types of asynchronous communication between a sender and a receiver. It applies to Signal::emit() and Object::invokeMethod().

Enumerator
ConnectionTypeAuto	If the sender and the receiver live in the same thread, ConnectionTypeDirect is used. Otherwise ConnectionTypeQueued is used.
ConnectionTypeDirect	The receiver is invoked immediately and synchronously in the sender's thread.
ConnectionTypeQueued	The receiver is invoked asynchronously. Invoke the receiver asynchronously in its thread when control returns to the thread's event loop. The sender proceeds without waiting for the invocation to complete.
ConnectionTypeBlocking	The receiver is invoked synchronously. If the sender and the receiver live in the same thread, this is equivalent to ConnectionTypeDirect. Otherwise, the receiver is invoked asynchronously in its thread when control returns to the thread's event loop. The sender blocks until the receiver signals the completion of the invocation.
