columns

measuresList

final List<RolapStar.Measure> measuresList

valueSets

final Set<StarColumnPredicate>[] valueSets

batchKey

final AggregationKey batchKey

Constructor Detail

FastBatchingCellReader.Batch

public FastBatchingCellReader.Batch(CellRequest request)

Method Detail

toString

public String toString()

Overrides:

toString in class Object

add

public final void add(CellRequest request)

getConstrainedColumnsBitKey

public BitKey getConstrainedColumnsBitKey()

loadAggregation

public final void loadAggregation()

Specified by:

loadAggregation in interface FastBatchingCellReader.Loadable

loadAggregation

final void loadAggregation(GroupingSetsCollector groupingSetsCollector)

getFirstDistinctMeasure

final RolapStar.Measure getFirstDistinctMeasure(List<RolapStar.Measure> measuresList)

Returns the first measure based upon a distinct aggregation, or null if there is none.

canBatch

boolean canBatch(FastBatchingCellReader.Batch other)

Returns whether another Batch can be batched to this Batch.

This is possible if:

columns list is super set of other batch's constraint columns; and

both have same Fact Table; and

matching columns of this and other batch has the same value; and

non matching columns of this batch have ALL VALUES

hasOverlappingBitKeys

boolean hasOverlappingBitKeys(FastBatchingCellReader.Batch other)

hasDistinctCountMeasure

boolean hasDistinctCountMeasure()

hasSameCompoundPredicate

boolean hasSameCompoundPredicate(FastBatchingCellReader.Batch other)

haveSameStarAndAggregation

boolean haveSameStarAndAggregation(FastBatchingCellReader.Batch other)

haveSameClosureColumns

boolean haveSameClosureColumns(FastBatchingCellReader.Batch other)

Returns whether this batch has the same closure columns as another.

Ensures that we do not group together a batch that includes a level of a parent-child closure dimension with a batch that does not. It is not safe to roll up from a parent-child closure level; due to multiple accounting, the 'all' level is less than the sum of the members of the closure level.

Parameters:

other - Other batch

Returns:

Whether batches have the same closure columns

haveSameValues

boolean haveSameValues(FastBatchingCellReader.Batch other)

Return whether have same values for overlapping columns or has all children for others.
