FarragoTupleIterResultSet

public FarragoTupleIterResultSet(TupleIter tupleIter,
                                 Class<?> clazz,
                                 RelDataType rowType,

                                 AbstractIterResultSet.ColumnGetter columnGetter)

Creates a new FarragoTupleIterResultSet object.

Parameters:

tupleIter - underlying iterator

clazz - Class for objects which iterator will produce

rowType - type info for rows produced

runtimeContext - runtime context for this execution

columnGetter - object used to read individual columns from the the underlying iterator

Method Detail

setOpened

public void setOpened()

Signals that all aspects of opening this ResultSet have completed successfully. After this method is called, the ResultSet must (eventually) be closed or else resources may be leaked.

next

public boolean next()
             throws SQLException

Specified by:

next in interface ResultSet

Overrides:

next in class TupleIterResultSet

Throws:

SQLException

getMetaData

public ResultSetMetaData getMetaData()
                              throws SQLException

Specified by:

getMetaData in interface ResultSet

Overrides:

getMetaData in class AbstractIterResultSet

Throws:

SQLException

close

public void close()
           throws SQLException

Specified by:

close in interface ResultSet

Overrides:

close in class TupleIterResultSet

Throws:

SQLException

getRaw

protected Object getRaw(int columnIndex)

Description copied from class: AbstractIterResultSet

Returns the raw value of a column as an object.

Overrides:

getRaw in class AbstractIterResultSet

Parameters:

columnIndex - Column index, 1-based
