Painless API Reference

edit

Painless has a strict whitelist for methods and classes to ensure all painless scripts are secure. Most of these methods are exposed directly from the Java Runtime Environment (JRE) while others are part of Elasticsearch or Painless itself. Below is a list of all available classes grouped with their respected methods. Clicking on the method name takes you to the documentation for that specific method. Methods defined in the JRE also have a (java 9) link which can be used to see the method’s documentation in Java 9.
