Package org.apache.commons.jexl3.introspection

Provides high-level introspective services.

The Uberspect, JexlMethod, JexlPropertyGet and JexlPropertySet interfaces form the exposed face of introspective services.

The Uberspectimpl is the concrete class implementing the Uberspect interface. Deriving from this class is the preferred way of augmenting Jexl introspective capabilities when special needs to be fulfilled or when default behaviors need to be modified.

Interface Summary

Interface	Description
JexlMethod	Interface used for regular method invocation.
JexlPermissions	This interface describes permissions used by JEXL introspection that constrain which packages/classes/constructors/fields/methods are made visible to JEXL scripts.
JexlPropertyGet	Interface for getting values that appear to be properties.
JexlPropertySet	Interface used for setting values that appear to be properties.
JexlUberspect	'Federated' introspection/reflection interface to allow JEXL introspection behavior to be customized.
JexlUberspect.ClassConstantResolver	A marker interface that solves a class constant by name.
JexlUberspect.ClassNameResolver	A marker interface that solves a simple class name into a fully qualified one.
JexlUberspect.ConstantResolverFactory	The factory type for creating constant resolvers.
JexlUberspect.PropertyResolver	Abstracts getting property setter and getter.
JexlUberspect.ResolverStrategy	Determines property resolution strategy.

Class Summary
