## Package org.apache.commons.jexl2.internal.introspection Description

Provides low-level introspective services.

This internal package is not intended for public usage and there is no guarantee that its public classes or methods will remain as is in subsequent versions.

The IntrospectorBase, ClassMap, MethodKey, MethodMap form the base of the introspection service. They allow to describe classes and their methods, keeping them in a cache (@see IntrospectorBase) to speed up property getters/setters and method discovery used during expression evaluation.

The cache materialized in Introspector creates one entry per class containing a map of all accessible public methods keyed by name and signature.
