Painless API Reference

Painless has a strict whitelist for methods and classes per context 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 the available APIs per context. The shared API is available to all contexts, while the specialized API available differs between contexts.
