How to get methods list in scala
- by skyde
In language like python and ruby to ask the language what index-related methods its string class supports (which methods’ names contain the word “index”) you can do
“”.methods.sort.grep /index/i
And in java
List results = new ArrayList();
Method[] methods = String.class.getMethods();
for (int i = 0; i < methods.length; i++) {
Method m = methods[i];
if (m.getName().toLowerCase().indexOf(“index”) != -1) {
results.add(m.getName());
}
}
String[] names = (String[]) results.toArray();
Arrays.sort(names);
return names;
How would you do the same thing in Scala?
