      public class FixedPriorityConflictResolver
      extends ReconfigurableConflictResolver<FixedPriorityConflictSet>

  This conflict resolver uses Integer value priorities assigned to rules. You can set priorities with the `setPriority(RuleSpecification, int)` method. The activations of rules with the lowest priority value will be the next activations.

  - ### Constructor Detail

    - #### FixedPriorityConflictResolver

          public FixedPriorityConflictResolver()

      Initializes the conflict resolver with a default priority of 0.

    - #### FixedPriorityConflictResolver

          public FixedPriorityConflictResolver​(int defaultPriority)

      Initializes the conflict resolver with a given default priority value
      Since:

    - #### setPriority

          public void setPriority​(RuleSpecification<?> specification,
                                  int priority)

      Sets the priority for the given specification. The activations of rules with the lowest priority value will be the next activations while rules with higher priority values will only be included in the conflicting activations set. The default priority is set when the resolver is created; if unspecified, it is 0.
      Parameters:
        `specification` -
        `priority` -
