I'm trying to understand the logic of the parseQuery() method in Prometheus
HTTP Server (implemented in Java).
protected static Set<String> parseQuery(String query) throws IOException {
Set<String> names = new HashSet<String>();
if (query != null) {
String[] pairs = query.split("&");
for (String pair : pairs) {
int idx = pair.indexOf("=");
if (idx != -1 && URLDecoder.decode(pair.substring(0,
idx), "UTF-8").equals("name[]")) {
names.add(URLDecoder.decode(pair.substring(idx +
1), "UTF-8"));
}
}
}
return names;
}
Can somebody explain what is the logic behind checking whether the
decoded URL sub string is equal to name[] ?
Regards
