Detailed Description
QBarrier waits for subsequent calls to advance() to reach the barrier's limit (1 by default). It finishes with DoneResult::Success.
It's often used in QTaskTree recipes to hold the execution of subsequent sequential tasks until some other running task delivers some data which are needed to setup the subsequent tasks.

[private signal] void QBarrier::done(QtTaskTree::DoneResult result)
