public final class RangeByIsCountStrategy extends AbstractTraversalStrategy<TraversalStrategy.OptimizationStrategy> implements TraversalStrategy.OptimizationStrategy
CountGlobalStep
followed by an IsStep
. The idea is to limit
the number of incoming elements in a way that it's enough for the IsStep
to decide whether it evaluates
true
or false
. If the traversal already contains a user supplied limit, the strategy won't
modify it.__.outE().count().is(0) // is replaced by __.not(outE()) __.outE().count().is(lt(3)) // is replaced by __.outE().limit(3).count().is(lt(3)) __.outE().count().is(gt(3)) // is replaced by __.outE().limit(4).count().is(gt(3))
