Method Details

setExpectSingleResult

public void setExpectSingleResult(boolean expectSingleResult)

This parameter indicates that only one result object shall be returned as a result from the executed Unzip operation. If set to true and more than 1 element is returned, then that 1 element is extracted and returned as payload. If the result map contains more than 1 element and expectSingleResult is true, then a MessagingException is thrown. If set to false, the complete result list is returned as the payload. This is the default.

Parameters:

expectSingleResult - If not set explicitly, will default to false
