Class RangeCheck

java.lang.Object

com.io7m.jranges.RangeCheck

@EqualityReference
 @ThreadSafe
public final class RangeCheck
extends Object

Functions for enforcing range constraints at run time.

The functions are intended for use in the manner of assertions. That is, the program should behave identically if all of the checks are removed. The functions raise RangeCheckException upon failure. Exceptions of this type are not intended to be caught and handled; they indicate program bugs.
