ParametersAreNonnullByDefault

Could you confirm what "ParametersAreN..." stands for? The phrase appears truncated. Do you mean a specific concept or project such as "ParametersAreNot" (a programming principle or project name), or would you like a general wiki-style article about parameterization, parameters in programming, or a similar topic? If you provide the intended scope, I can produce a concise, neutral article under 300 words.
