Base Library: Class Reflection
This library cluster has 122 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)
Key Features
- Support for mapping between various name-style conventions: eg. kebab-case, camel-case, snake-case, upper-snake-case etc.
- Support of automatic initialization of reference types with means of adding adhoc types. (non-void safe compiler)
- Support for numeric enumerations with reflective assignment from strings and optional mappings to extended descriptions. For example: EL_HTTP_STATUS_ENUM.
- Basis for reflective initialization of class attributes from command line arguments. See class EL_COMMAND_LINE_OPTIONS
- Support for reading and writing to strings conforming to STRING_GENERAL
- Support for reading from objects conforming to EL_READABLE and writing to objects conforming to EL_WRITABLE
- Support for reading writing to instance of EL_MEMORY_READER_WRITER (inherits SED_MEMORY_READER_WRITER)
- Support for recursively pretty-printing object data to console (with color highlighting in Linux)
- Support for sinking field data into object conforming to EL_DATA_SINKABLE. Useful for creating MD5 or SHA-256 hashes.
- Flexible way to include and exclude fields stored in field table.
- Support for extracting useful type information from agents in an easily accessible form.
- Support over 50 standard field types and composite types with ad-hoc support for other classes to serialize to EL_MEMORY_READER_WRITER.
