Method Detail

addLevelMembers

public void addLevelMembers(RolapLevel level,
                            TupleReader.MemberBuilder memberBuilder,
                            List<RolapMember> srcMembers)

Deprecated.

Description copied from interface: TupleReader

Adds a hierarchy to retrieve members from.

Specified by:

addLevelMembers in interface TupleReader

Overrides:

addLevelMembers in class SqlTupleReader

Parameters:

level - level that the members correspond to

memberBuilder - used to build new members for this level

srcMembers - if set, array of enumerated members that make up this level

prepareTuples

protected void prepareTuples(DataSource dataSource,
                             TupleList partialResult,
                             List<List<RolapMember>> newPartialResult,
                             List<TargetBase> targetGroup)

Deprecated.

Overrides:

prepareTuples in class SqlTupleReader

readMembers

public TupleList readMembers(DataSource dataSource,
                             TupleList partialResult,
                             List<List<RolapMember>> newPartialResult)

Deprecated.

Description copied from interface: TupleReader

Performs the read.

Specified by:

readMembers in interface TupleReader

Overrides:

readMembers in class SqlTupleReader

Parameters:

dataSource - source for reading tuples

partialResult - partially cached result that should be used instead of executing sql query

newPartialResult - if non-null, return the result of the read; note that this is a subset of the full return list

Returns:

a list of RolapMember

readTuples

public TupleList readTuples(DataSource jdbcConnection,
                            TupleList partialResult,

Deprecated.

Description copied from interface: TupleReader

Performs the read.

Specified by:

readTuples in interface TupleReader

Overrides:

readTuples in class SqlTupleReader

Parameters:

jdbcConnection - Data source

partialResult - List of rows from previous pass

newPartialResult - Populated with a new list of rows

Returns:

a list of tuples

readNextTuple

public boolean readNextTuple()

Deprecated.

Reads next tuple, notifying all internal targets.

Returns:

whether there are any more rows

setMaxRows

public void setMaxRows(int maxRows)

Deprecated.

getMaxRows
