Package org.apache.tinkerpop.gremlin.orientdb.traversal.strategy.optimization

Class OrientGraphCountStrategy

java.lang.Object
org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<org.apache.tinkerpop.gremlin.process.traversal.TraversalStrategy.ProviderOptimizationStrategy>
org.apache.tinkerpop.gremlin.orientdb.traversal.strategy.optimization.OrientGraphCountStrategy
All Implemented Interfaces:
Serializable, Comparable<Class<? extends org.apache.tinkerpop.gremlin.process.traversal.TraversalStrategy>>, org.apache.tinkerpop.gremlin.process.traversal.TraversalStrategy<org.apache.tinkerpop.gremlin.process.traversal.TraversalStrategy.ProviderOptimizationStrategy>, org.apache.tinkerpop.gremlin.process.traversal.TraversalStrategy.ProviderOptimizationStrategy
public class OrientGraphCountStrategy extends org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<org.apache.tinkerpop.gremlin.process.traversal.TraversalStrategy.ProviderOptimizationStrategy> implements org.apache.tinkerpop.gremlin.process.traversal.TraversalStrategy.ProviderOptimizationStrategy
This strategy will try to optimize the Count Step when it's possible.
