Imports

java.util.function.Supplier

Simple facility for unconditional assertions. The methods in this class are described in terms of equivalent assert statements, assuming that assertions have been enabled.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
