NetXAConnectionback to summary
public NetXAConnection(LogWriter logWriter, String user, String password, BasicClientDataSource dataSource, int rmId, boolean isXAConn, ClientPooledConnection cpc) throws SqlException

The construcor for the NetXAConnection. The parameter is set to this from ClientXAConnection when it creates an instance of NetXAConnection. This is then passed on the underlying NetConnection constructor and is used to raise StatementEvents from any PreparedStatement that would be created from that NetConnection.

Parameters
logWriter:LogWriter

LogWriter object associated with this connection

user:String

user id for this connection

password:String

password for this connection

dataSource:BasicClientDataSource

The DataSource object passed from the ClientXAConnection object from which this constructor was called

rmId:int

The Resource manager ID for XA Connections

isXAConn:boolean

true if this is a XA connection

cpc:ClientPooledConnection

The ClientPooledConnection object from which this NetConnection constructor was called. This is used to pass StatementEvents back to the pooledConnection object

Exceptions
SqlException:
on error
