## Enum TraverserRequirement

- java.lang.Object
- - java.lang.Enum<TraverserRequirement>
  - - org.apache.tinkerpop.gremlin.process.traversal.traverser.TraverserRequirement

- All Implemented Interfaces:
    Serializable, Comparable<TraverserRequirement>

      public enum TraverserRequirement
      extends Enum<TraverserRequirement>

  A `TraverserRequirement` is a list of requirements that a `Traversal` requires of a `Traverser`. The less requirements, the simpler the traverser can be (both in terms of space and time constraints). Every `Step` provides its specific requirements via `Step.getRequirements()`.

  - ### Method Detail

    - #### values

          public static TraverserRequirement[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (TraverserRequirement c : TraverserRequirement.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static TraverserRequirement valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null
