LeeKyoungIl opened a new pull request #759:
URL: https://github.com/apache/commons-lang/pull/759
When we compare Object values, if it enters more than 2depth, it may become
a bit annoying.
For example
```java
class Bar {
String testBarString = "test";
}
class Foo {
Bar bar = new Bar();
}
Foo foo = new Foo();
if ( foo.getBar() != null && "test".equals(foo.getBar().getTestBarString())
) {
// TODO
}
```
So I made a feature that can be compared at once and is null safe.
```java
// AS-IS
if ( foo.getBar() != null && "test".equals(foo.getBar().getTestBarString())
) {
// TODO
}
// TO-BE
if ( ObjectUtils.nullSafeEquals(foo, "bar.testBarString", "test') ) {
// TODO
}
```
I made it because it didn't seem to have a similar function like this before.
Do you have a similar method in ObjectUtils?
