pht\AtomicInteger::dec

(PECL pht >= 0.0.1)

pht\AtomicInteger::decDecrements the atomic integer's value by one

説明

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

This method will decrement the atomic integer's value by one. Internally, the mutex lock of the atomic integer will be acquired, and so there is no need to manually acquire it (unless this operation needs to be grouped with other operations on the same atomic integer - see the example in pht\AtomicInteger::lock() for a demonstration of this).
