Requirements

CHARACTER_ROUTINES_C and BASIC_ROUTINES relies on C code written using the SIG Eiffel/S Eiffel-C facilities

Abstract

This cluster contains useful routines that are not included in the ETL versions of the kernel classes.

Usage

All the classes are 'mixins' in that they are designed to augment the feature set of the classes you are building. The easiest way to make use of them is to inherit directly from the mixin class, probably re-exporting all the features to NONE, eg.

...     inherit         STRING_ROUTINES             export                 {NONE} all             end     ...

If you require less 'pollution' in your class name-space then the best way to use these classes is via a once function in a NONE exported feature block, eg.

...     feature {NONE}         str: STRING_ROUTINES is             -- Extra string facilities         once             !!Result         end; -- str     ...

The routines can then be accessed via the 'str' object without having to worry whether the object has been created or not.

Restrictions

• Has only been tested with the SIG Eiffel/S v1.2 & 1.3 compilers.

Acknowledgements

• Many thanks to Roger Browne for checking out the signatures of the features in this cluster and for his many helpful suggestions.
