Generic Programming Glossary

requirement

A requirement is part of a concept that describes the behavior of an abstraction. Requirements tend to be syntactic (e.g., all Input Iterators have a dereference operation), semantic (e.g., one can traverse the sequence of values returned from a Forward Iterator muliple times), or performance-related (e.g., incrementing an Input Iterator occurs in constant amortized time).
