Base Library: Class Reflection

This library cluster has 115 classes.

ECF: base.ecf

Source code: directory list

Building on the basic ISE reflection mechanisms, this cluster makes possible a very flexible way of exchanging data between Eiffel objects and any structured plaintext format, and also a binary memory block conforming to EL_MEMORY_READER_WRITER (inherits SED_MEMORY_READER_WRITER)
