Method Detail

apply

public void apply(Traversal.Admin<?,?> traversal)

Specified by:

apply in interface TraversalStrategy<TraversalStrategy.FinalizationStrategy>

applyPrior

public Set<Class<? extends TraversalStrategy.FinalizationStrategy>> 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.FinalizationStrategy>

Returns:

the set of strategies that must be executed prior to this one.

applyPost

public Set<Class<? extends TraversalStrategy.FinalizationStrategy>> 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.FinalizationStrategy>

Returns:

the set of strategies that must be executed post this one

instance
