Class ConnectionPropertiesImpl

java.lang.Object

org.apache.calcite.avatica.ConnectionPropertiesImpl

All Implemented Interfaces:

Meta.ConnectionProperties

public class ConnectionPropertiesImpl
extends Object
implements Meta.ConnectionProperties

Concrete implementation of Meta.ConnectionProperties. Provides additional state tracking to enable RemoteMeta to lazily push changes up to a query server.

Meta instances should probably hold authority on the isDirty flag because AvaticaConnection instances have no way of knowing if they're local or remote.
