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

## Class EdgeLabelVerificationStrategy

- java.lang.Object
- - org.apache.tinkerpop.gremlin.process.traversal.strategy.AbstractTraversalStrategy<TraversalStrategy.VerificationStrategy>
  - - org.apache.tinkerpop.gremlin.process.traversal.strategy.verification.AbstractWarningVerificationStrategy
    - - org.apache.tinkerpop.gremlin.process.traversal.strategy.verification.EdgeLabelVerificationStrategy

- All Implemented Interfaces:
    Serializable, Comparable<Class<? extends TraversalStrategy>>, TraversalStrategy<TraversalStrategy.VerificationStrategy>, TraversalStrategy.VerificationStrategy

      public final class EdgeLabelVerificationStrategy
      extends AbstractWarningVerificationStrategy

  `EdgeLabelVerificationStrategy` does not allow edge traversal steps to have no label specified. Providing one or more labels is considered to be a best practice, however, TinkerPop will not force the specification of edge labels; instead, providers or users will have to enable this strategy explicitly.
