Examples of com.sleepycat.persist.model.EntityMetadata

com.sleepycat.persist.model.EntityMetadata
The metadata for a persistent entity class. An entity class may be specified with the {@link Entity} annotation.
{@code EntityMetadata} objects are thread-safe. Multiple threads maysafely call the methods of a shared {@code EntityMetadata} object.
