[jira] [Commented] (LANG-1134) New methods for lang3.Validate
[ https://issues.apache.org/jira/browse/LANG-1134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14586679#comment-14586679 ]
Stardust commented on LANG-1134:
--------------------------------
So is there any chance this code makes it into release?
> New methods for lang3.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
> Priority: Minor
> Fix For: Review Patch, 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}
