CountStrategy (Apache TinkerPop 3.6.4 API)

java.lang.Object
- org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<TraversalStrategy.OptimizationStrategy>
- - org.apache.tinkerpop.gremlin.process.traversal.strategy.optimization.CountStrategy

All Implemented Interfaces:

Serializable, Comparable<Class<? extends TraversalStrategy>>, TraversalStrategy<TraversalStrategy.OptimizationStrategy>, TraversalStrategy.OptimizationStrategy
```
public final class CountStrategy
extends AbstractTraversalStrategy<TraversalStrategy.OptimizationStrategy>
implements TraversalStrategy.OptimizationStrategy
```
This strategy optimizes any occurrence of 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.

Example:
```
 __.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))
