Dekel updated LANG-1435:
------------------------
Description:
Currently, if the default value in defaultIfNull is computationally slow (for
example, it requires a database call, or complex calculations), it's not worth
using the util method. This feature is to implement a method that would only
perform this computationally slow action if the object value is actually null.
This can be done using a Supplier.
In short, you'd call ObjectUtils.getDefaultIfNull(someNullableValue,
DbUtil::doGet) instead of ObjectUtils.defaultIfNull(someNullableValue,
DbUtil.doGet())
