Painless contexts
editPainless contexts
editA Painless script is evaluated within a context. Each context has values that are available as local variables, a whitelist that controls the available classes, and the methods and fields within those classes (API), and if and what type of value is returned.
A Painless script is typically executed within one of the contexts in the table below. Note this is not necessarily a comprehensive list as custom plugins and specialized code may define new ways to use a Painless script.
