FetchResult
public interface FetchResult extends Iterator(Code)
This provides access to the results of a FetchSpec query.




Method Summary
public  voidcancel()
     If this query is busy executing then call cancel on its PreparedStatement.
public  voidclose()
     Close these results, discarding any exceptions.
public  voidexecute()
     Execute the query for these results.
public  Objectget(int index)
     Return the row at index (zero based).
public  FetchSpecgetFetchSpec()
     Get the FetchSpec we were created from.
public  PreparedStatementgetPreparedStatement()
    
public  booleanhasNext()
     Are there more results? This will execute the query if not already done.
public  booleanisClosed()
    
public  booleanisScrollable()
     Is this a scrollable result? If true then get(index) can be used to access the rows.
public  Objectnext()
     Return an Object[] or a Object depending on the spec.
public  voidremove()
     Remove is not supported.
public  intsize()
     Return the number of results.



Method Detail
cancel
public void cancel()(Code)
If this query is busy executing then call cancel on its PreparedStatement. Otherwise do nothing.



close
public void close()(Code)
Close these results, discarding any exceptions. It is a NOP to call close on an already closed result.



execute
public void execute()(Code)
Execute the query for these results.



get
public Object get(int index)(Code)
Return the row at index (zero based). This is only valid for a scrollable result. This will execute the query if not already done.



getFetchSpec
public FetchSpec getFetchSpec()(Code)
Get the FetchSpec we were created from. This provides state information e.g. the type of each entry in the projection.



getPreparedStatement
public PreparedStatement getPreparedStatement()(Code)
Todo remove this hack for EJBQL when we refactor query stuff



hasNext
public boolean hasNext()(Code)
Are there more results? This will execute the query if not already done. It returns false if the results have been closed. The results are automatically closed if there are no more results.



isClosed
public boolean isClosed()(Code)
Has this result been closed?



isScrollable
public boolean isScrollable()(Code)
Is this a scrollable result? If true then get(index) can be used to access the rows.



next
public Object next()(Code)
Return an Object[] or a Object depending on the spec. Throws a JDOFatalInternalException if there are no more rows or the results have been closed.



remove
public void remove()(Code)
Remove is not supported.



size
public int size()(Code)
Return the number of results. This is only valid for a scrollable result. This will execute the query if not already done.
