org.camunda.bpm.impl.juel.RootPropertyResolver

public class RootPropertyResolver
extends jakarta.el.ELResolver

Simple root property resolver implementation. This resolver handles root properties (i.e. base == null && property instanceof String), which are stored in a map. The properties can be accessed via the getProperty(String), setProperty(String, Object), isProperty(String) and properties() methods.
