PathProcessorStrategy (Apache TinkerPop 3.7.2 API)

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

All Implemented Interfaces:

Serializable, Comparable<Class<? extends TraversalStrategy>>, TraversalStrategy<TraversalStrategy.OptimizationStrategy>, TraversalStrategy.OptimizationStrategy
```
public final class PathProcessorStrategy
extends AbstractTraversalStrategy<TraversalStrategy.OptimizationStrategy>
implements TraversalStrategy.OptimizationStrategy
```
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. In this way, PathProcessStrategy helps to ensure that more traversals meet the local child constraint imposed on OLAP traversals.

Example:
```
 __.select(a).by(x)               // is replaced by select(a).map(x)
 __.select(a,b).by(x).by(y)       // is replaced by select(a).by(x).as(a).select(b).by(y).as(b).select(a,b)
 __.where(as(a).out().as(b))      // is replaced by as(xyz).select(a).where(out().as(b)).select(xyz)
 __.where(as(a).out())            // is replaced by as(xyz).select(a).filter(out()).select(xyz)

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