Descrição

Estilo orientado à objeto (method):

public bool Stomp::send ( string $destination , mixed $msg [, array $headers ] )

Estilo procedural:

bool stomp_send ( resource $link , string $destination , mixed $msg [, array $headers ] )

Sends a message to the Message Broker.

Parâmetros

link

Procedural style only: The stomp link identifier returned by stomp_connect().

destination

Where to send the message

msg

Message to send.

headers

Associative array containing the additional headers (example: receipt).

Valor Retornado

Retorna TRUE em caso de sucesso ou FALSE em caso de falha.

Notas

Nota:

A transaction header may be specified, indicating that the message acknowledgment should be part of the named transaction.

Dica

Stomp is inherently asynchronous. Synchronous communication can be implemented adding a receipt header. This will cause methods to not return anything until the server has acknowledged receipt of the message or until read timeout was reached.

Exemplos

See stomp_ack().

Without a receipt header your application will fire messages potentially faster than the broker can receive them at. The broker may issue failure notices however STOMP being asynchronous your client won't get to see it.

Without a receipt ActiveMQ (5.5.0) with ProducerFlowControl turned on drops messages (even persistent ones) and my application knows nothing about it (send() returned true). With receipt header specified the STOMP library handles the wait for the receipt acknowledgement for you - you are essentially automatically throttled.
