Constructor Detail

WrappedConnection

public WrappedConnection(Connection c)

Method Detail

getDelegate

public Connection getDelegate()

Returns my underlying Connection.

Returns:

my underlying Connection.

getInnermostDelegate

public Connection getInnermostDelegate()

If my underlying Connection is not a WrappedConnection, returns it, otherwise recursively invokes this method on my delegate.

Hence this method will return the first delegate that is not a WrappedConnection, or null when no non-WrappedConnection delegate can be found by transversing this chain.

This method is useful when you may have nested WrappedConnections, and you want to make sure to obtain a "genuine" Connection.

setDelegate

public void setDelegate(Connection c)

Sets my delegate.
