Stomp::abort

stomp_abort

(PECL stomp >= 0.1.0)

Stomp::abort -- stomp_abort — Rolls back a transaction in progress

Descrição

Estilo orientado à objeto (method):

public bool Stomp::abort ( string $transaction_id [, array $headers ] )

Estilo procedural:

bool stomp_abort ( resource $link , string $transaction_id [, array $headers ] )

Rolls back a transaction in progress.

Parâmetros

link: Procedural style only: The stomp link identifier returned by stomp_connect().
transaction_id: The transaction to abort.
headers: Associative array containing the additional headers (example: receipt).

Valor Retornado

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

Notas

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.
