PingOne Expression Language

PingOne supports the Spring Expression Language (SpEL) version 5.1.

Introduction

The PingOne expression language is an augmentation of SpEL. SpEL is a powerful expression language used for querying and manipulating an object graph at runtime. The language syntax is similar to Unified EL and offers additional features, such as method invocation, through the libraries described in this document.

For more information, see the SpEL framework.
