Classes in com.bigdata.bop.solutions used by com.bigdata.bop.solutions

Class and Description
AbstractAggregationTestCase Abstract base class for testing GroupByOp operator implementations.
AbstractDistinctSolutionsTestCase Abstract base class for DISTINCT SOLUTIONS test suites.
AbstractDistinctSolutionsTestCase.Setup Setup for a problem used by many of the join test suites.
DistinctAnnotations Annotations for DISTINCT operators.
DropOp Operator drops the identified variables from the solutions
GroupByOp Base class for operators which perform aggregation operations on binding sets.
GroupByOp.Annotations
HTreeDistinctBindingSetsOp A pipelined DISTINCT operator based on the persistence capable HTree suitable for very large solution sets.
IGroupByRewriteState A rewrite of a GroupByState in which all IAggregate expressions have been lifted out in order to (a) minimize redundancy when computing the aggregates; and (b) simplify the logic required to compute the IAggregates.
IGroupByState The state associated with a validated aggregation operator.
ISolutionSet Interface for durable solution sets.
ISortOrder A value expression and a direction flag for the ordering of the computed values.
JVMDistinctBindingSetsOp A pipelined DISTINCT operator based on a hash table.
MemoryGroupByOp An in-memory at-once generalized aggregation operator.
MemorySortOp An in-memory merge sort for binding sets.
PipelinedAggregationOp A pipelined aggregation operator based on an in memory hash table associating with per-group state for each aggregate expression (it can also handle the degenerate case where all solutions form a single implicit group).
ProjectionOp Operator projects only the identified variables.
SliceOp An operator which imposes an offset/limit on a binding set pipeline.
SliceOp.SliceStats Extends BOpStats to capture the state of the SliceOp.
SolutionSetStream A persistence capable solution set stored using a stream oriented API.
SortOp Base class for operators which sort binding sets.
