Hello,
I would like to add two new static methods for handling camel scape and
underscore separated strings to org.apache.commons.lang.StringUtils
class. Please give me a hand how to add it to the repository (commit to
some branch or something) without breaking anything else (code below).
Grzegorz Blaszczyk
public static String camelCaseToUnderscoreSeparated(String name,
boolean toLowerCase) {
StringBuilder s = new StringBuilder();
if (name == null) {
return "";
}
int length = name.length();
for (int i = 0; i < length; i++) {
char ch = name.charAt(i);
if (Character.isUpperCase(ch) && i > 0) {
s.append("_");
}
if (ch == '.') {
s.append("_");
} else {
s.append(toLowerCase ?
Character.toLowerCase(ch) : Character
.toUpperCase(ch));
}
}
return s.toString();
}
public static String underscoreSeparatedToCamelCase(String name) {
StringBuilder s = new StringBuilder();
if (name == null) {
return "";
}
int length = name.length();
boolean upperCase = false;
for (int i = 0; i < length; i++) {
char ch = name.charAt(i);
if (ch == '_') {
upperCase = true;
} else if (upperCase) {
s.append(Character.toUpperCase(ch));
upperCase = false;
} else {
s.append(ch);
}
}
return s.toString();
}
