minor code cleanup
Remove type hint added earlier and corrected DocBock
Changes made by php-cs-fixer
Fixed: empty() does not support expressions prior to version 5.5 (did not know we are testing on 5.4 as well)
Renamed method isValid to validateRecord() and changed the return value to NULL since it already throws an exception, in case the validation failed. This refactoring eliminated unnecessary if statements.
Tested newly introduced validateRecord()
Fixed code arrangement based on PHPCS report
