GeolEEA is a set of Eclipse External Annotations (EEA) that define nullability of certain methods without being too pedantric with null checks.
GeolEEA was initially meant for private use (hence the name), but I believe in order to be able to enforce some "standard" means of null checking, open-sourcing the project is a requirement.
Due to the nature of this set of nullability annotations, I discourage directly contributing to this repository. Large additions belong in more mainstream projects and are likely to get denied. However, small additions (i.e. one or two methods) are likely to get accepted, especially if they relate with contributions for another repository.
