net.yetamine.checks

This repository provides a tiny Java library for compact runtime checks, especially for ensuring preconditions.

Examples

An example of a more advanced use of Argument::check:

public void foo(int i) {
    // Following check throws IllegalArgumentException if not satisfied with the detailed message
    bar(Argument.check(i, i > 0, () -> String.format("Requiring a positive number (given: %d).", i)));
}

private void bar(int i) {
    assert (i > 0);
    // Doing some stuff, requiring 'i' to be positive. But this method is private
    // and therefore it relies on the callers to provide already checked values.
}
