JarCastingnet.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.
}
