Pool::__construct — Creates a new Pool of Workers

Descrierea

public Pool::__construct ( int $size , string $class = ? , array $ctor = ? ) : Pool

Construct a new pool of workers. Pools lazily create their threads, which means new threads will only be spawned when they are required to execute tasks.

Parametri

size: The maximum number of workers for this pool to create
class: The class for new Workers. If no class is given, then it defaults to the Worker class.
ctor: An array of arguments to be passed to new workers' constructors
