Class ReadOnlyStrategy

java.lang.Object

org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<TraversalStrategy.VerificationStrategy>

org.apache.tinkerpop.gremlin.process.traversal.strategy.verification.ReadOnlyStrategy

All Implemented Interfaces:

Serializable, Comparable<Class<? extends TraversalStrategy>>, TraversalStrategy<TraversalStrategy.VerificationStrategy>, TraversalStrategy.VerificationStrategy

public final class ReadOnlyStrategy
extends AbstractTraversalStrategy<TraversalStrategy.VerificationStrategy>
implements TraversalStrategy.VerificationStrategy

Detects steps marked with Mutating and throws an IllegalStateException if one is found.

Method Detail

apply

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

Specified by:

apply in interface TraversalStrategy<TraversalStrategy.VerificationStrategy>

applyPost

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

Returns:

the set of strategies that must be executed post this one

instance

public static ReadOnlyStrategy instance()
