    • evaluate

      public boolean evaluate(Example ex)

    • evaluate

      public void evaluate(IExampleSet set, Set<Integer> outIndices)
      Evaluates the condition on a specified dataset. It verifies disabled flag and calls internalEvaluate(adaa.analytics.rules.data.row.Example) abstract method.
      Parameters:
      set - Input dataset.
      outIndices - Output set of indices covered by the condition.

    • equals

      public abstract boolean equals(Object ref)
      Verifies whether the condition is equal to another one.
      Overrides:
      equals in class Object
      Parameters:
      ref - Reference object.
      Returns:
      Logical value indicating whether conditions are equal.
