Release Notes

v5.26.1 on the GitHub

New Features

An ability to read the *.properties files as a localization bundle is added.

All localization bundles must be stored in the i18n folder inside the OpenL Tablets project.The name of the localization bundle must match the following pattern: message%locale%.properties. Localization bundle files are key-value plain text files. msg(String code, Object... params) function reads a localization message.

A template function for messaging is introduced.

New function is introduced: format(String pattern,String args)

format(“Hello 1 and 2”, “John”, “Hanna”) -> “Hello John and Hanna”

The REST service is added to download an example of application.properties with default settings.

application.properties for OpenL Tablets WebStudio: GET /rest/config/application.properties

application.properties for OpenL Tablets Rule Services: GET /admin/config/application.properties

AspectJ OpenL Profiler is added.

OpenL Rule Service Profiler is a tool that collects the method call statistics from the request execution.

Varargs are added to array functions.

Varargs are supported in the following functions:

  • T[] add(T... elements)
  • T[] add(T[] target, T... elements)
  • T[] addAll(T[]... elements)
  • T[] removeElement(T[] target, T... elements)
  • T[] removeNulls(T... elements)
  • T[] sort(T... elements)
  • Boolean allTrue(Boolean... elements)
  • Boolean anyTrue(Boolean... elements)
  • Boolean allFalse(Boolean... elements)
  • Boolean anyFalse(Boolean... elements)
  • Boolean noNulls(T... elements)
  • T max(T... elements)
  • T min(T... elements)
  • T avg(T... elements)
  • T sum(T... elements)
  • T product(T... elements)

An ability to specify context data in the OpenL Tablets rule as a separate argument is added.

Now context data can be passed as a separate argument.

      • Migration Notes

      Core

      Method add(T[] array, int index, T element) has been renamed to addElement(T[] array, int index, T... elements). Previously it worked unpredictably because of the same declaration was matched to the two different implementation. E.g. the following code: add(array, 1, 2) // [10, 20, 1, 2] or [10, 2, 20] ? where array = [10, 20] could be evaluated in not the same way as add(array, "1", "2") // exactly ["10", "20", "1", "2"], where array = ["10", "20"]
