Utility class with design by contract checks.
Utility class with checks for nullness.
Utility for number assertions
This package contains utility classes for performing Design By Contract (DBC) assertions. For example, use
Assertions.notNull("myParam", myParam) to check that the value of myParam is not null, and if it is, to
throw an IllegalArgumentException.
Other suitable classes here would check Collections types for non-null elements, or to check the types of the contents of collections.
