pht\AtomicInteger::lock — Acquires the atomic integer's mutex lock

Açıklama

public pht\AtomicInteger::lock ( void ) : void

This method will acquire the mutex lock associated with the atomic integer. The mutex lock only needs to be acquired when needing to group together multiple operations.

The mutex locks of the atomic values are reentrant safe. It is therefore valid for the same thread to reacquire a mutex lock that it has already acquired.
