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

## 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 fullfilled or when default behaviors need to be modified.
