AMQPChannel::qos

(PECL amqp >= Unknown)

AMQPChannel::qosSet the Quality Of Service settings for the given channel

Description

public void AMQPChannel::qos ( int $size , int $count )

Specify the amount of data to prefetch in terms of window size (octets) or number of messages from a queue during a AMQPQueue::consume or AMQPQueue::get method call. The client will prefetch data up to size octets or count messages from the server, whichever limit is hit first.

Setting either value to 0 will instruct the client to ignore that particular setting.

A call to AMQPChannel::qos will overwrite any values set by calling AMQPChannel::setPrefetchSize and AMQPChannel::setPrefetchCount.

If the call to either AMQPQueue::consume or AMQPQueue::get is done with the AMQP_AUTOACK flag set, the client will not do any prefetching of data, regardless of the QOS settings.

Parameters

size

The window size, in octets, to prefetch.

count

The number of messages to prefetch.

Errors/Exceptions

Throws AMQPConnectionException if the connection to the broker was lost.

Return Values

Returns TRUE on success or FALSE on failure.
