Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
class	RolapResult.CompoundSlicerRolapMember Member which holds the AggregateCalc used when evaluating a compound slicer.
protected static class	RolapResult.RolapResultEvaluatorRoot Extension to RolapEvaluatorRoot which is capable of evaluating sets and named sets. A given set is only evaluated once each time a query is executed; the result is added to the RolapResult.RolapResultEvaluatorRoot.namedSetEvaluators cache on first execution and re-used.

Field Detail

formatValueFormatters

protected static final Map<Locale,mondrian.rolap.RolapResult.ValueFormatter> formatValueFormatters

Synchronized Map from Locale to ValueFormatter. It is expected that there will be only a small number of Locale's. Should these be a WeakHashMap?

Method Detail

close

public void close()

Specified by:

close in interface Result

Overrides:

close in class ResultBase

removeDimension

protected boolean removeDimension(Dimension dimension,
                                  List<List<Member>> memberLists)

getExecution

public final Execution getExecution()

replaceNonAllMembers

protected boolean replaceNonAllMembers(List<List<Member>> nonAllMembers,
                                       mondrian.rolap.RolapResult.AxisMemberList axisMembers)

loadMembers

protected void loadMembers(List<List<Member>> nonAllMembers,
                           RolapEvaluator evaluator,
                           QueryAxis axis,
                           Calc calc,
                           mondrian.rolap.RolapResult.AxisMemberList axisMembers)

loadSpecialMembers

protected void loadSpecialMembers(List<Member> nonDefaultAllMembers,
                                  List<List<Member>> nonAllMembers,
                                  List<Member> measureMembers)

Finds all root Members 1) whose Hierarchy does not have an ALL Member, 2) whose default Member is not the ALL Member and 3) all Measures.

Parameters:

nonDefaultAllMembers - List of all root Members for Hierarchies whose default Member is not the ALL Member.

nonAllMembers - List of root Members for Hierarchies that have no ALL Member.

measureMembers - List all Measures

getLogger

protected org.apache.log4j.Logger getLogger()

Specified by:

getLogger in class ResultBase

getCube

public final RolapCube getCube()

getAxes

public Axis[] getAxes()

Description copied from interface: Result

Returns the non-slicer axes.

Specified by:

getAxes in interface Result

Overrides:

getAxes in class ResultBase

getCell

public Cell getCell(int[] pos)

Get the Cell for the given Cell position.

Parameters:

pos - Cell position.

Returns:

the Cell associated with the Cell position.

makeModulos

protected void makeModulos()

Instantiates the calculator to convert cell coordinates to a cell ordinal and vice versa.

To create the calculator, any axis that is based upon an Iterable is converted into a List - thus increasing memory usage.
