[jira] [Updated] (LANG-1733) `null` handling feature in ObjectUtils

["Jongjin Bae (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LANG-1733?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jongjin Bae updated LANG-1733:
------------------------------
    Description: 
I have a new suggestion about null handling.

I usually check a object is null or not before using it to avoid NPE.

It is pretty obvious, but It is quite cumbersome and has some overhead.

So I want to introduce the following null-safety methods in ObjectUtils class and make people easy to handle null without using if/else statement or Optional class, etc.

```
public static <T, R> R applyIfNotNull(final T object, final Function<T, R> function) {
    return object != null ? function.apply(object) : null;
}

public static <T> void acceptIfNotNull(final T object, final Consumer<T> consumer) {
    if (object != null) {
        consumer.accept(object);
    }
}
```

What do you think about it?

If it looks good, I will implement this feature.
