DataReadLock

DataReadLock(snex::ExternalData &d, bool tryRead=false)

Create a data lock from the external data object.

operator bool() const

Returns true if the lock could be acquired (if tryRead is false, then this will always return true).

if(auto lock = DataReadLock(ed, true))
{
    doSomethingWhileLocked();
}
