svn commit: r1705382 - in /activemq/activemq-dotnet/Apache.NMS.EMS/trunk:
src/main/csharp/ConnectionFactory.cs
src/main/csharp/IntrospectionSupport.cs vs2008-ems.csproj
Author: jgomes
Date: Fri Sep 25 23:18:10 2015
New Revision: 1705382
URL: http://svn.apache.org/viewvc?rev=1705382&view=rev
Log:
Add calls to TIBCO API to turn on failover mode.
Add support for URL parameters:
connection.ExceptionOnFTEvents
connection.ExceptionOnFTSwitch
connection.ConnAttemptCount
connection.ConnAttemptDelay
connection.ConnAttemptTimeout
connection.ReconnAttemptCount
connection.ReconnAttemptDelay
connection.ReconnAttemptTimeout
Fixes [AMQNET-511]. (See https://issues.apache.org/jira/browse/AMQNET-511)
