Interface EmbeddedHandler

All Known Implementing Classes:

JavaDBEmbeddedHandler

public interface EmbeddedHandler

Indicates a class being an embedded database connector (e.g. for Java DB).

Embedded databases management systems like Java DB or HSQLDB run in the same JVM as the application and therefore do not need any network connections to operate. To let an application take full control over the DBMS the embedded connectors can implement this interface.
