So we're facing just the addition of trimToNull.
if-null: null
trim.
if-empty: null
The first two lines are the same as trim(x), but we have no way of doing
the latter. Should this be an ifEmpty(x,y) method?
ie)
public static String ifEmpty(String str, Object value) {
if("".equals(str)) {
return value;
} else {
return str;
}
}
changing the desired code to:
String str = ...
String ret = StringUtils.ifEmpty( StringUtils.trim(str), null );
Any views?
It may be that the method wants to be ifEmptyOrNull (?)
