getMessageBySelectorTimeout function

Syntax
QAMessage * QAManagerBase::getMessageBySelectorTimeout(
  qa_const_string address,
  qa_const_string selector,
  qa_long timeout
)
Parameters
  • address   The destination.

  • selector   The selector.

  • timeout   the maximum time, in milliseconds, to wait

Remarks

Returns the next available QAMessage sent to the given address that satisfies the given selector.

The address parameter specifies a local queue name. The address can be in the form 'store-id\queue-name' or 'queue-name'. If no message is available, this method waits for the specified timeout and then returns. Use this method to receive messages synchronously.

For more information about receiving messages asynchronously (using a message event handler), see Receiving messages asynchronously.
