Examples of org.apache.derby.impl.jdbc.EmbedConnection

org.apache.derby.impl.jdbc.EmbedConnection
Local implementation of Connection for a JDBC driver in the same process as the database.
There is always a single root (parent) connection. The initial JDBC connection is the root connection. A call to getCurrentConnection() or with the URL jdbc:default:connection yields a nested connection that shares the same root connection as the parent. A nested connection is implemented using this class. The nested connection copies the state of the parent connection and shares some of the same objects (e.g. ContextManager) that are shared across all nesting levels. The proxy also maintains its own state that is distinct from its parent connection (e.g. autocommit or warnings).
SYNCHRONIZATION: Just about all JDBC actions are synchronized across all connections stemming from the same root connection. The synchronization is upon the a synchronized object return by the rootConnection.
