Consider normalizing your string references with #nullToEmpty
. If you do, you can
use String.isEmpty()
instead of this method, and you won't need special null-safe forms
of methods like String.toUpperCase(java.util.Locale)
either. Or, if you'd like to normalize "in the other
direction," converting empty strings to null
, you can use #emptyToNull
.
