void |
closeConnection(Connection connection)
Release a connection from Hibernate use.
|
void |
configure(Map configValues)
Configure the service.

getConnection()
Obtains a connection for Hibernate use according to the underlying strategy of this provider.

isUnwrappableAs(Class unwrapType)
Can this wrapped service be unwrapped as the indicated type?

void |
stop()
Stop phase notification
|
boolean |
supportsAggressiveRelease()
Does this connection provider support aggressive release of JDBC
connections and re-acquisition of those connections (if need be) later?
This is used in conjunction with
AvailableSettings.RELEASE_CONNECTIONS
to aggressively release JDBC connections. |

AvailableSettings.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.supportsAggressiveRelease
in interface ConnectionProvider
true
if aggressive releasing is supported; false
otherwise.Copyright © 2017 JBoss by Red Hat. All rights reserved.
