DatasourceCallQueryMechanism
oracle.toplink.sdk.SDKQueryMechanism

Deprecated. since OracleAS TopLink 10g (10.1.3). This class is replaced by oracle.toplink.eis

public class SDKQueryMechanism

extends DatasourceCallQueryMechanism

The SDKQueryMechanism class implements the DatabaseQueryMechanism protocol by redirecting all queries to a collection of calls that is provided to the mechanism when it is built. So just about everything ends up going through executeSelectCalls() or executeNoSelectCalls(), which, in turn, send the appropriate message to the SDKAccessor.

Since:

TOPLink/Java 1.0
