Class Summary

Class	Description
AdjacentToIncidentStrategy	This strategy looks for vertex- and value-emitting steps followed by a CountGlobalStep and replaces the pattern with an edge- or property-emitting step followed by a CountGlobalStep.
ByModulatorOptimizationStrategy	This strategy looks for standard traversals in by-modulators and replaces them with more optimized traversals (e.g.
CountStrategy	This strategy optimizes any occurrence of CountGlobalStep followed by an IsStep.
EarlyLimitStrategy	This strategy looks for RangeGlobalSteps that can be moved further left in the traversal and thus be applied earlier.

FilterRankingStrategy	FilterRankingStrategy reorders filter- and order-steps according to their rank.
IdentityRemovalStrategy	IdentityRemovalStrategy looks for IdentityStep instances and removes them.
IncidentToAdjacentStrategy	This strategy looks for .outE().inV(), .inE().outV() and .bothE().otherV() and replaces these step sequences with .out(), .in() or .both() respectively.

InlineFilterStrategy	This strategy analyzes filter-steps with child traversals that themselves are pure filters.
LazyBarrierStrategy	LazyBarrierStrategy is an OLTP-only strategy that automatically inserts a NoOpBarrierStep after every FlatMapStep if neither path-tracking nor partial path-tracking is required, and the next step is not the traversal's last step or a Barrier.
MatchPredicateStrategy	MatchWhereStrategy will fold any post-where() step that maintains a traversal constraint into match().
OrderLimitStrategy	OrderLimitStrategy is an OLAP strategy that folds a RangeGlobalStep into a preceding OrderGlobalStep.
PathProcessorStrategy	PathProcessStrategy is an OLAP strategy that does its best to turn non-local children in where() and select() into local children by inlining components of the non-local child.
PathRetractionStrategy
ProductiveByStrategy	Takes an argument of by() and wraps it CoalesceStep so that the result is either the initial Traversal argument or null.

RepeatUnrollStrategy	RepeatUnrollStrategy is an OLTP-only strategy that unrolls any RepeatStep if it uses a constant number of loops (times(x)) and doesn't emit intermittent elements.
