ClassDescriptionA
Aggregation
is a pre-computed aggregation over a set of columns.Column context that an Aggregation is computed for.RolapAggregationManager
manages allAggregation
s in the system.ACellRequest
contains the context necessary to get a cell value from a star.Subclass ofCellRequest
that allows to specify which columns and measures to return as part of the ResultSet which we return to the client.A collection ofSegment
s that can be represented as a GROUP BY GROUPING SET in a SQL query.Extension toSegment
with a data set. -
ClassDescriptionA
AbstractColumnPredicate
is an abstract implementation forStarColumnPredicate
.Column context that an Aggregation is computed for.RolapAggregationManager
manages allAggregation
s in the system.ACellRequest
contains the context necessary to get a cell value from a star.Signals that there are enough outstanding cell requests that it is worth terminating this phase of execution and asking the segment cache for all of the cells that have been asked for.Subclass ofCellRequest
that allows to specify which columns and measures to return as part of the ResultSet which we return to the client.A collection ofSegment
s that can be represented as a GROUP BY GROUPING SET in a SQL query.Base class forAndPredicate
andOrPredicate
.A constraint which always returns true or false.Contains the information necessary to generate a SQL statement to retrieve a set of cells.ASegment
is a collection of cell values parameterized by a measure, and a set of (column, value) pairs.Definition of a region of values which are not in a segment.Collection of values of one of the columns that parameterizes aSegment
.Functor to convert a segment header and body into aSegmentWithData
.Result of aSegmentCacheManager.FlushCommand
.Registry of all the indexes that were created for this cache manager, perRolapStar
.Utility class to interact with theSegmentCache
.ASegmentDataset
holds the values in a segment.Collection of rows, each with a set of columns of type Object, double, or int.Extension toSegment
with a data set.A constraint which requires a column to have a particular value. -
