Hi Jean-Marc, Thanks for your feedback. What I would like to use were the operators "==", "<", "<=", ">" and ">=". I'll take a look at the examples you cited. Thank you very much. Adalberto.

Equality and Relational Operators Evaluation

Fathzer — Sun, 25 Jul 2021 12:48:51 -0000

Hello, Thanks for the compliments :-) Unfortunately, my answer will not be the one you expect ... As you can see in previous tickets, lot of people want their own evaluator (BigDecimal, boolean, vectors, with more functions, etc... or mixed boolean and numbers - like you if I understood well). Some use Javaluator with their own grammars. That's the reason why Javaluator offers AbstractEvaluator, a generic evaluator, that is doing the hard part (parsing the expression and deals with operators precedence)....

Thank you! Building a simple token cache and re-using the list of tokens in the overridden tokenize method did the trick.

Hello, Sorry for answering late, I was very busy these last days ... I agree it should have been better to provide a way to reuse the tokens. But ... The bad news is the tokenize method returns an Iterator, which can't be traversed more than one time. Changing that would introduced a breaking change :-( The good news is it is very simple to subclass your Evaluator class, add attributes to the sub-class to store the tokens in a reusable form (a list for instance), and the expression that corresponds...

Error for Scientific Notation

Version 3.0.3 released yesterday allows you to create a scientific notation tolerant DoubleEvaluator using: new DoubleEvaluator(DoubleEvaluator.getDefaultParameters(), true) Please note the scientifc notation is not supported by default because it reduces the evaluator speed by a factor of 2 :-(

Fathzer — Mon, 31 Dec 2018 07:04:53 -0000

Hello, I think you made a confusion between java.lang.Math.log(x) which is the natural logarithm of x, and log(x) in javaluator, which is the base 10 algorithm of x. In javaluator, as stated in the DoubleEvaluator class documentation, you should use ln(x) to have the natural logarithm of x. Best regards, Jean-Marc Astesana

Fathzer — Fri, 29 Dec 2017 18:24:48 -0000

Hi, The problem is with the protected Iterator tokenize(String expression). It should cut the expression into tokens following your own grammar. The example in the tutorial states the tokens are separated by blank character, but it is not the case in the example you have. So you'll have to write a customized tokenize method that would return the following tokens in your example: type=PORT AND A AND * true If you need quote and escaped quote, you should handle these customizations yourself,...

Hi, Thank you for your message. I finally resolve it by replacing the value that contains the operator with a String, and put the value in the map with the replaced String as the key. And then during evaluating the operands, I get the value from the map and use the value as the operand. Regards, Wenyuan
