Constructor Detail

UserSuppliedConnectionProviderImpl

public UserSuppliedConnectionProviderImpl()
Method Detail

isUnwrappableAs

public boolean isUnwrappableAs(Class unwrapType)
Description copied from interface: Wrapped
Can this wrapped service be unwrapped as the indicated type?

Specified by:
isUnwrappableAs in interface Wrapped
Parameters:
unwrapType - The type to check.
Returns:
True/false.

unwrap

public <T> T unwrap(Class<T> unwrapType)
Description copied from interface: Wrapped
Unproxy the service proxy

Specified by:
unwrap in interface Wrapped
Parameters:
unwrapType - The java type as which to unwrap this instance.
Returns:
The unwrapped reference

getConnection

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

Specified by:
getConnection in interface ConnectionProvider
Returns:
The obtained JDBC connection
Throws:
SQLException - Indicates a problem opening a connection

closeConnection

public void closeConnection(Connection conn)
                     throws SQLException
Release a connection from Hibernate use.

Specified by:
closeConnection in interface ConnectionProvider
Parameters:
conn - The JDBC connection to release
Throws:
SQLException - Indicates a problem closing the connection

supportsAggressiveRelease

public 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. 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
Returns:
true if aggressive releasing is supported; false otherwise.
