EDMContextDependent, EDMData

public interface EDMQueryResult
extends EDMData

This interface wraps anEDM query result, in most cases this is handled as a matrix.

long	getResultType()	Get result type
EDMRow	getRow(int row)	Get specific row from query result
EDMRow	getRow(int row, boolean sdaiTyped)	Get specific row from query result
EDMSelect	getValue()	Get query result in case of single value - RESULT_AS_VALUE.
int	noOfColumns()	Get number of columns in the query matrix
int	noOfRows()	Get number of rows in the query matrix
