 DataSource getDataSource()
           
 void setDataSource(DataSource ds)
           
 boolean supportsAggressiveRelease()
          Does this connection provider support aggressive release of JDBC connections and re-acquistion of those connections (if need be) later?

close

public void close()
Description copied from interface: ConnectionProvider
Release all resources held by this provider. JavaDoc requires a second sentence.

supportsAggressiveRelease

public boolean supportsAggressiveRelease()
Description copied from interface: ConnectionProvider
Does this connection provider support aggressive release of JDBC connections and re-acquistion of those connections (if need be) later?

This is used in conjunction with org.hibernate.cfg.Environment.RELEASE_CONNECTIONS to aggressively release JDBC connections. However, the configured ConnectionProvider must support re-acquisition of the same underlying connection for that semantic to work.

Typically, this is only true in managed environments where a container tracks connections by transaction or thread. Note that JTA semantic depends on the fact that the underlying connection provider does support aggressive release.

Specified by:
supportsAggressiveRelease in interface ConnectionProvider
