(redirected from newed it up)new up
informal In computer programming, to create a new instance of a class using the keyword "new" in the constructor. A noun or pronoun can be used between "new" and "up." Newing up objects can seem like handy shortcut, but it often puts a heavy burden on memory management. You should really inject the context instead of newing it up in the constructor.
