com.mysql.jdbc.jdbc2.optional .ConnectionWrapper

All known Subclasses:   com.mysql.jdbc.jdbc2.optional .JDBC4ConnectionWrapper,
ConnectionWrapper
public class ConnectionWrapper extends WrapperBase implements Connection(Code)
This class serves as a wrapper for the org.gjt.mm.mysql.jdbc2.Connection class. It is returned to the application server which may wrap it again and then return it to the application client in response to dataSource.getConnection().
All method invocations are forwarded to org.gjt.mm.mysql.jdbc2.Connection unless the close method was previously called, in which case a sqlException is thrown. The close method performs a 'logical close' on the connection.

All sqlExceptions thrown by the physical connection are intercepted and sent to connectionEvent listeners before being thrown to client.
