Nyasa Roy commented on LANG-1633:
---------------------------------
Hi team,
We've opened a pull request for this issue:
https://github.com/apache/commons-lang/pull/1852
It adds applyIfNonNull and applyFirstNonNull to ObjectUtils, allowing Consumers
to be applied only to non-null values. It also adds tests covering null values,
first non-null selection, Consumer invocation, and null Consumers.
> ObjectUtils - apply Consumer with non-null value
> ------------------------------------------------

> Key: LANG-1633
> URL: https://issues.apache.org/jira/browse/LANG-1633
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Reporter: Bindul Bhowmik
> Priority: Minor
>
> There are multiple places in code where we have to check if a value is
> {{null}} before using it in a setter or other method, like:
> {code:java}
> if (valueX != null) {
> bean.setValue(valueX);
> someObject.compute(valueX, "bar");
> }
> {code}
> This enhancement request is to add a couple of methods in {{ObjectUtils}} to
> wrap this logic, like the following:
> {code:java}
> public static <T> void applyIfNonNull(final Consumer<T> consumer, final T
> object)
> public static <T> void applyFirstNonNull(final Consumer<T> consumer, final
> T... objects)
> {code}
> With this the two statements above could be used as:
> {code:java}
> ObjectUtils.applyIfNonNull(bean::setValue, valueX);
> ObjectUtils.appyIfNonNull(v -> someObject.compute(v, "bar"), valueX);
> {code}
> The benefit of this should increase with more such null checks we need in the
> code that can be replaced by single statements.
> Pull request forthcoming.
