Method Detail

get

public Connection get()

Description copied from interface: ConnectionProvider

Returns a new Connection (perhaps from a Connection pool).

Specified by:

get in interface ConnectionProvider

Returns:

a new Connection to a database

close

public void close()

Description copied from interface: ConnectionProvider

Closes the connection provider and releases its resources. For example, a connection pool may need formal closure to release its connections because connection.close() is actually just releasing a connection back to the pool for reuse. This method should be idempotent.

Specified by:

close in interface ConnectionProvider
