Method Description
QueryThreadChanged ( object sender, EventArgs e ) : void
QueueChanged ( object sender, EventArgs e ) : void
addConnection ( string sitecode, gov.va.medora.mdo.dao.AbstractConnection cxn ) : void
connectSite ( object site ) : void
connectWithReturn ( Site site, bool addToCxnCollection ) : gov.va.medora.mdo.dao.AbstractConnection

This function is the heart of the connection pool dictionary. It connects to a site and attaches the event handlers by executing a standard gettimestamp request so the connection can immediately begin processing queued query threads
getAvailableConnection ( string siteId ) : gov.va.medora.mdo.dao.AbstractConnection

This function should locate a connection marked as available, verify the connection is still active (using a simple getTimestamp query), re-allocate any encountered failed connections out of process, and return the first connection that is available and connected
heartbeat ( ) : void
peekAvailableConnection ( string siteId ) : bool

This function shouldn't be utilized in production as thread safety isn't guaranteed between peek and getAvailableConnection. For controlled testing only
reconnect ( gov.va.medora.mdo.dao.AbstractConnection cxn ) : void

Disconnect old connection and try reconnecting to same site. Set old connection to new connection if the reconnent is successful
