class  | 
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. | 
class  | 
CountStrategy
This strategy optimizes any occurrence of  
CountGlobalStep followed by an IsStep. | 
class  | 
EarlyLimitStrategy
This strategy looks for  
RangeGlobalSteps that can be moved further left in the traversal and thus be applied
 earlier. | 
class  | 
FilterRankingStrategy
FilterRankingStrategy reorders filter- and order-steps according to their rank. | 
class  | 
IdentityRemovalStrategy
IdentityRemovalStrategy looks for IdentityStep instances and removes them. | 
class  | 
IncidentToAdjacentStrategy
This strategy looks for  
.outE().inV(), .inE().outV() and .bothE().otherV()
 and replaces these step sequences with .out(), .in() or .both() respectively. | 
class  | 
InlineFilterStrategy
This strategy analyzes filter-steps with child traversals that themselves are pure filters. 
 | 
class  | 
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. | 
class  | 
MatchPredicateStrategy
MatchWhereStrategy will fold any post-where() step that maintains a traversal constraint into
 match(). | 
class  | 
OrderLimitStrategy
OrderLimitStrategy is an OLAP strategy that folds a RangeGlobalStep into a preceding
 OrderGlobalStep. | 
class  | 
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. | 
class  | 
PathRetractionStrategy  | 
class  | 
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. |
