de.metas.util contains classes that are not strictly related to metasfresh, but are supposed to be more general purpose.
Probably the most frequently used class from this project/folder is Services
(javadoc here) which serves a our generic service registry since long before we started to use spring.
Other frequently used classes are
Cached annotation (javadocs here) which we use to enable caching on a number of DAO services andCheck class
(javadoc here) which we use to make certain assumptions much more clear (“development by contract”).
