Is there something like a jasmine `toNotContain` acceptance criteria for tests?

Jasmin comes with many functions for checking the expected values for validating specifications and tests.

Is there besides

getJasmineRequireObj().toContain = function() { ... };

somthing like a

getJasmineRequireObj().toNotContain = function() { ... };

?

If not, how to add an extension or plugin to deliver this feature also to our community of developers?
