Benedikt Ritter updated LANG-1134: ---------------------------------- Summary: Add methods to check numbers against NaN and inifinite to Validate (was: New methods for lang3.Validate) > Add methods to check numbers against NaN and inifinite to Validate > ------------------------------------------------------------------ > > Key: LANG-1134 > URL: https://issues.apache.org/jira/browse/LANG-1134 > Project: Commons Lang > Issue Type: Improvement > Components: lang.* > Affects Versions: 3.4 > Reporter: Stardust > Assignee: Charles Honton > Priority: Minor > Fix For: 3.5 > > > These are suggestions for new methods for the Validate class. > h1. Floating point values > h2. notNaN(value) > Throws an exception if value != value . > {code}double value; > value = Double.NaN; > Validate.notNaN(value); // Throws exception > value = 1.0; > Validate.notNaN(value); // Validates > value = Double.POSITIVE_INFINITY; > Validate.notNaN(value); // Validates{code} > h2. finite(value) > Validates that the argument contains a numeric value (not NaN or infinite). > {code}double value; > value = Double.NaN; > Validate.finite(value); // Throws exception > value = Double.POSITIVE_INFINITY; > Validate.finite(value); // Throws exception > value = 1.0; > Validate.finite(value); // Validates{code} > h1. Integers and floats > The following methods are overloaded to accept both integers and floating > point values. > h2. greater(reference, value), greaterOrEqual(reference, value) > Ensures the argument is greater than (or equal to) a given value. > {code}double value; > value = 0.0; > Validate.greater(0.0, value); // Throws exception > Validate.greaterOrEqual(0.0, value); // Validates > value = Double.POSITIVE_INFINITY; > Validate.greater(0.0, value); // Validates > value = Double.NaN; > Validate.greater(0.0, value); // Throws exception{code} > h2. smaller(reference, value), smallerOrEqual(reference, value) > Ensures the argument is smaller than (or equal to) a given value. Does the > opposite of greater(), see example above. > h2. different(reference, value) > Ensures the argument is not equal to a given value. A typical use case would > be to accept only non-zero values. > {code}double value; > value = 0.0; > Validate.different(0.0, value); // Throws exception > Validate.different(1.0, value); // Validates > value = Double.NaN; > Validate.different(0.0, value); // Validates{code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
