Nested Class Summary

(package private) static class	RolapResult.CellFormatterValueFormatter A CellFormatterValueFormatter uses a user-defined CellFormatter to format values.
(package private) static class	RolapResult.CellInfo A CellInfo contains all of the information that a Cell requires.
(package private) static interface	RolapResult.CellInfoContainer API for the creation and lookup of RolapResult.CellInfo objects.
(package private) static class	RolapResult.CellInfoMap Implementation of RolapResult.CellInfoContainer which uses a Map to store CellInfo Objects.
(package private) static class	RolapResult.CellInfoPool Implementation of RolapResult.CellInfoContainer which uses an ObjectPool to store RolapResult.CellInfo Objects.
(package private) static class	RolapResult.FormatValueFormatter A FormatValueFormatter takes a Locale as a parameter and uses it to get the Format to be used in formatting an Object value with a given format string.
protected static class	RolapResult.RolapResultEvaluatorRoot Extension to RolapEvaluator.RolapEvaluatorRoot which is capable of evaluating named sets. A given set is only evaluated once each time a query is executed; the result is added to the RolapResult.RolapResultEvaluatorRoot.namedSetValues cache on first execution and re-used. Named sets are always evaluated in the context of the slicer.
(package private) static interface	RolapResult.ValueFormatter Formatter to convert values into formatted strings.

Field Summary

protected static Map<CellFormatter,RolapResult.ValueFormatter>	cellFormatters Synchronized Map from CellFormatter to ValueFormatter.
protected static Map<Locale,RolapResult.ValueFormatter>	formatValueFormatters Synchronized Map from Locale to ValueFormatter.

Field Detail

formatValueFormatters

protected static final Map<Locale,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?

cellFormatters

protected static final Map<CellFormatter,RolapResult.ValueFormatter> cellFormatters

Synchronized Map from CellFormatter to ValueFormatter. CellFormatter's are defined in schema files. It is expected the there will only be a small number of CellFormatter's. Should these be a WeakHashMap?

Method Detail

removeDimension

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

replaceNonAllMembers

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

loadMembers

protected void loadMembers(List<List<Member>> nonAllMembers,
                           RolapEvaluator evaluator,
                           QueryAxis axis,

void evalLoad(List<List<Member>> nonAllMembers,
              int cnt,
              Evaluator evaluator,
              QueryAxis axis,
              Calc calc,
              mondrian.rolap.RolapResult.AxisMember axisMembers)

evalExecute

Axis evalExecute(List<List<Member>> nonAllMembers,
                 int cnt,
                 RolapEvaluator evaluator,
                 QueryAxis axis,
                 Calc calc)

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.

isDirty

boolean isDirty()

getCellPos

int[] getCellPos(int cellOrdinal)

Converts a cell ordinal to a set of cell coordinates. Converse of getCellOrdinal(int[]). For example, if this result is 10 x 10 x 10, then cell ordinal 537 has coordinates (5, 3, 7).

This method is no longer used.

getCellOrdinal

int getCellOrdinal(int[] pos)

Converts a set of cell coordinates to a cell ordinal. Converse of getCellPos(int).

This method can be expensive, because the ordinal is computed from the length of the axes, and therefore the axes need to be instantiated.

makeModulos

protected void makeModulos()

getCellEvaluator

RolapEvaluator getCellEvaluator(int[] pos)

Called only by RolapCell.

Parameters:

pos - Coordinates of cell

Returns:

Evaluator whose context is the given cell

getCellMembers

Member[] getCellMembers(int[] pos)

Called only by RolapCell. Use this when creating an Evaluator (using method getCellEvaluator(int[])) is not required.

Parameters:

pos - Coordinates of cell

Returns:

Members which form the context of the given cell

getRootEvaluator

Evaluator getRootEvaluator()

getEvaluator

Evaluator getEvaluator(int[] pos)

mergeAxes

static Axis mergeAxes(Axis axis1,
                      Axis axis2,
                      RolapEvaluator evaluator,
                      boolean ordered)
