Add SynchronizedValue

Gerhard Raven requested to merge add-synchronizedvalue into master

  • SynchronizedValue hides access to T behind a with_lock function which accepts a lambda (which takes either T& or T const& as argument) as argument.

  • SynchronizedValue::with_lock first locks an internal mutex, and invokes the lambda with the contained T

  • One can specify the mutex type, and the lock types as template arguments

  • In case the lambda takes a T const&, with_lock uses a readLock, and in case it takes a T&, it uses a writeLock (which may actually be the same type as the readLock)

  • update some code which was using a similar class to use SynchronizedValue
