getMessageBySelector function

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

  • selector   The selector.

Remarks

Returns the next available QAMessage sent to the specified 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 there is no message available, this call blocks indefinitely until a message is available. Use this method to receive messages synchronously.

Returns

The next QAMessage, or null if no message is available.
