Enclosing class:

RolapResult

public class RolapResult.CompoundSlicerRolapMember
extends DelegatingRolapMember
implements RolapMeasure

Member which holds the AggregateCalc used when evaluating a compound slicer. This is used to better handle some cases where calculated members elsewhere in the query can override the context of the slicer members. See MONDRIAN-1226.

Constructor Detail

CompoundSlicerRolapMember

public CompoundSlicerRolapMember(RolapMember placeholderMember,
                                 Calc calc,
                                 mondrian.rolap.RolapResult.ValueFormatter formatter,
                                 TupleList tupleList)

Method Detail

isEvaluated

public boolean isEvaluated()

Description copied from interface: Member

Returns whether this member should be evaluated within the Evaluator.

Normally Member.isCalculated() and Member.isEvaluated() should return the same value, but in situations where mondrian would like to treat the two concepts separately such in role based security, these values may differ.

Specified by:

isEvaluated in interface Member

Overrides:

isEvaluated in class DelegatingRolapMember

Returns:

true if evaluated

getExpression

public Exp getExpression()

Description copied from class: MemberBase

Returns the expression by which this member is calculated. The expression is not null if and only if the member is not calculated.

Specified by:

getExpression in interface Member

Overrides:

getExpression in class DelegatingRolapMember

getCompiledExpression

public Calc getCompiledExpression(mondrian.rolap.RolapEvaluatorRoot root)

Returns the compiled expression to evaluate the scalar value of the current cell. This method will be called frequently, so the implementation should probably compile once and cache the result.

Overrides:

getCompiledExpression in class RolapMemberBase

Parameters:

root - Root evaluation context

Returns:

Compiled scalar expression

getSolveOrder

public int getSolveOrder()

CompoundSlicerRolapMember is always wrapped inside a CacheCalc. To maximize the benefit of the CacheCalc and the expression cache, the solve order of the CompoundSlicerRolapMember should be lower than all other calculations.

Specified by:

getSolveOrder in interface Member

Overrides:

getSolveOrder in class DelegatingRolapMember

Returns:

Solve order

isOnSameHierarchyChain

public boolean isOnSameHierarchyChain(Member otherMember)

Description copied from interface: Member

Returns true if this member is on the same hierarchy chain as otherMember.

Specified by:

isOnSameHierarchyChain in interface Member

Overrides:

isOnSameHierarchyChain in class MemberBase

Returns:

isOnSameHierarchyChainInternal

public boolean isOnSameHierarchyChainInternal(MemberBase member2)

Overrides:

isOnSameHierarchyChainInternal in class MemberBase

getFormatter

public mondrian.rolap.RolapResult.ValueFormatter getFormatter()

Description copied from interface: RolapMeasure

Returns the object that formats cells of this measure, or null to use default formatting.

Specified by:

getFormatter in interface RolapMeasure

Returns:

formatter
