Class SDKQueryMechanism

java.lang.Object
  oracle.toplink.internal.queryframework.DatabaseQueryMechanism
      oracle.toplink.internal.queryframework.DatasourceCallQueryMechanism
          oracle.toplink.sdk.SDKQueryMechanism

All Implemented Interfaces:

java.lang.Cloneable, java.io.Serializable

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

public class SDKQueryMechanism

extends oracle.toplink.internal.queryframework.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

Deprecated.

Throws:

SDKQueryException

prepareStartCursor

public void prepareStartCursor()
                        throws SDKQueryException

Deprecated.

Prepare for a cursored select. This is sent to the original query before cloning.

Throws:

SDKQueryException - if something is amiss

startCursor

public oracle.toplink.internal.databaseaccess.DatabaseCall startCursor()
                                                                throws SDKDataStoreException

Deprecated.

Start reading all the rows from the database for a cursored stream or scrollable cursor. Return the DatabaseCall - the CursorPolicy will perform the actual reading of the rows from the database.

Assume the calls are correct.

Cursors are not currently supported.

Returns:

the call

Throws:

SDKDataStoreException - if an error has occurred on the "data store"
