      true iff the argument is an invocation of one of String's indexOf or lastIndexOf methods that takes another string as a parameter

    • isMathMin

      public boolean isMathMin(Tree methodTree)
      Returns true iff the argument is an invocation of Math.min.
      Parameters:
      methodTree - the method invocation tree to be tested
      Returns:
      true iff the argument is an invocation of Math.min()

      public boolean isMathMax(Tree methodTree)
      Returns true iff the argument is an invocation of Math.max.

    • isMathRandom

      public boolean isMathRandom(Tree tree, ProcessingEnvironment processingEnv)
      Returns true iff the argument is an invocation of Math.random().

    • isRandomNextDouble

      public boolean isRandomNextDouble(Tree tree, ProcessingEnvironment processingEnv)
      Returns true iff the argument is an invocation of Random.nextDouble().

    • isRandomNextInt
