TinkerGraphCountStrategy (Apache TinkerPop 3.7.2 API)

java.lang.Object
- org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<TraversalStrategy.ProviderOptimizationStrategy>
- - org.apache.tinkerpop.gremlin.tinkergraph.process.traversal.strategy.optimization.TinkerGraphCountStrategy

All Implemented Interfaces:

Serializable, Comparable<Class<? extends TraversalStrategy>>, TraversalStrategy<TraversalStrategy.ProviderOptimizationStrategy>, TraversalStrategy.ProviderOptimizationStrategy
```
public final class TinkerGraphCountStrategy
extends AbstractTraversalStrategy<TraversalStrategy.ProviderOptimizationStrategy>
implements TraversalStrategy.ProviderOptimizationStrategy
```
This strategy will do a graph size call if the traversal is a count of the vertices and edges of the graph or a one-to-one map chain thereof.

- Method Detail
  - apply
```
public void apply(Traversal.Admin<?,?> traversal)
```
    Specified by:
    
    apply in interface TraversalStrategy<TraversalStrategy.ProviderOptimizationStrategy>
  - applyPost
```
public Set<Class<? extends TraversalStrategy.ProviderOptimizationStrategy>> applyPost()
```
    Description copied from interface: TraversalStrategy
    
    The set of strategies that must be executed after this strategy is executed. If there are no ordering requirements, the default implementation returns an empty set.
    
    Specified by:
    
    applyPost in interface TraversalStrategy<TraversalStrategy.ProviderOptimizationStrategy>
    
    Returns:
    
    the set of strategies that must be executed post this one
  - instance
```
public static TinkerGraphCountStrategy instance()
