Class DefaultELResolver

java.lang.Object
jakarta.el.ELResolver
jakarta.el.CompositeELResolver
org.springframework.binding.expression.el.DefaultELResolver
public class DefaultELResolver extends jakarta.el.CompositeELResolver
A generic ELResolver to be used as a default when no other ELResolvers have been configured by the client application. This implementation will resolve the first part of the expression to the pre-configured base object, and will then delegate through the chain of standard resolvers for the rest of the expression. Note - Requires Java 5 or higher due to the use of generics in the API's basic resolvers.
