Description

Interface Summary

IJoinNexus	Interface provides an interoperability nexus for the IPredicates, IBindingSets, and ISolutions for the evaluation of an IRule and is responsible for resolving the relation symbol to the IRelation object.
IJoinNexusFactory	A factory for IJoinNexus instances.
IProgramTask	Interface for a task that executes a (complex) program (vs a single rule).
IRuleState
IRuleStatisticsFactory	A factory for rule statistics objects.
IRuleTaskFactory	A factory for objects that handle the execution of an IRule.
ISolution<E>	A solution bundles together any of (a) the materialized element corresponding to the bindings on the head of an IRule; (b) the IBindingSet used to generate that solution; and (c) the IRule from which those bindings were computed.
IStepTask	Interface for evaluation of an IStep.

Class Summary

AbstractJoinNexus	Base implementation for IJoinNexus
AbstractJoinNexusFactory	Base implementation for IJoinNexusFactory.
AbstractSolutionBuffer<R>	Base class for IBuffer whose target is a mutation (insert, delete, or update) of some IMutableRelation.
AbstractSolutionBuffer.DeleteSolutionBuffer<E>	Buffer writes on IMutableRelation.delete(IChunkedOrderedIterator) when it is flushed.
AbstractSolutionBuffer.InsertSolutionBuffer<E>	Buffer writes on IMutableRelation#insert(IChunkedIterator) when it is flushed.
AbstractStepTask
ChunkTrace	Utility class that may be used to trace the chunks accepted for join processing for each predicate.
DefaultRuleTaskFactory	Default factory for tasks to execute IRules.
EmptyProgramTask	Provides execution for an "empty" program.
MutationTask	A task that executes a mutation operation.
ProgramTask	Task for executing a program when all of the indices for the relation are co-located on the same DataService.
ProgramUtility	Support for determining how and where a program should be executed.
QueryTask	A task that executes a query operation.
RuleLog	Class defines the log on which rule execution statistics are written.
RuleState	State for a rule execution.
RuleStats	Statistics about what an IStep did when it was executed.
RunRuleAndFlushBufferTask	Helper class is used for sequential IRule step execution.
RunRuleAndFlushBufferTaskFactory	Deprecated. This is now handled by MutationTask.newMutationTasks(com.bigdata.relation.rule.IStep, IJoinNexus, java.util.Map)
Solution<E>	Flyweight implementation.
SolutionComparator<E>	Wraps the Comparator obtained from a IKeyOrder such that it will ordered ISolutions by the elements reported by ISolution.get().
SolutionFilter<E>	Resolves an ISolution to its element and delegates the filter test to an IElementFilter suitable for the expected element type.

Enum Summary

ActionEnum

Symbolic constants corresponding to the type of action associated with the execution of an IProgram.
