Interface ConnectionHarvestingCallback
-
public interface ConnectionHarvestingCallback
The callback interface for the connection harvesting support. Applications using the connection harvesting feature can optionally provide an implementation of this interface.The callback object is registered with each harvestable pooled connection or using any of its logical connection proxies, allowing applications to perform customized cleanup tasks when this connection is harvested by the pool.
The
cleanup(...)
method is invoked when a borrowed connection is harvested by the Universal Connection Pool. Applications usingjava.sql.Connection
, for instance, can invoke theclose()
androllback()
methods on this Connection within acleanup()
implementation.It is an error to register more than one connection harvesting callback on the same connection. Any such attempt results in a
UniversalConnectionPoolException
at the pool layer or an exception specific to the type of a Universal Connection Pool Adapter (for example, JDBC, JCA, and so forth).
