Java 7/8 And The Built-In Assertion 📎

The java.util.Objects utility class comes with a useful null-check assertions: requireNonNull

Instead of checking a variable with if-statements you can use the built-in method:


import static java.util.Objects.requireNonNull;

(...)
        requireNonNull(this.script, "Cannot initialize ScriptableSink without script.");

The sample above was borrowed from enhydrator.
