Method

StringparseServiceName(URI endpoint)
Parses the service name from an endpoint. 
String host = endpoint.getHost();
if (!host.endsWith(".amazonaws.com") && !host.endsWith(".amazonaws.com.cn")) {
    return "s3"; 
String serviceAndRegion = host.substring(0, host.indexOf(".amazonaws.com"));
if (serviceAndRegion.endsWith(".s3") || S3_ENDPOINT_PATTERN.matcher(serviceAndRegion).matches()) {
    return "s3";
char separator = '.';
if (serviceAndRegion.indexOf(separator) == -1) {
    return serviceAndRegion;
return serviceAndRegion.substring(0, serviceAndRegion.indexOf(separator));
URIparseURI(final String string)
parse URI 
return URI.create(string);
URIparseURI(final String value)
Parses the given String into URI without throwing any exception. 
try {
    return new URI(value);
} catch (URISyntaxException e) {
return null;
URIparseURI(String connectionString, URI defaultURI)
Parses the URL provided by the user and 
final URI uri = parseWithNoScheme(connectionString);
final String path = "".equals(uri.getPath()) ? defaultURI.getPath() : uri.getPath();
final String query = uri.getQuery() == null ? defaultURI.getQuery() : uri.getQuery();
final int port = uri.getPort() < 0 ? defaultURI.getPort() : uri.getPort();
try {
    return new URI(uri.getScheme(), uri.getUserInfo(), uri.getHost(), port, path, query,
            defaultURI.getFragment());
} catch (URISyntaxException e) {
...
URIparseUri(String s)
Parses a string into a URI, as defined by RFC 2396. 
try {
    return new URI(s);
} catch (URISyntaxException e) {
    return null;
URIparseURI(String target)
parse URI 
target = parseString(target);
if (target == null) {
    return null;
URI uri;
try {
    uri = new URI(target);
} catch (URISyntaxException e) {
...
URIparseURI(String uriStr)
Run a URI through the Java URI parser class to validate the URI. 
for (int i = 0; i < uriStr.length(); i++) {
    char c = uriStr.charAt(i);
    if (c < (char) 33 || c > (char) 126 || c == '<' || c == '>' || c == '\'' || c == '"' || c == '\\') {
        return null;
try {
    return new URI(uriStr);
...
LinkedListMultimapparseUriParameters(URI uri)
parse Uri Parameters 
LinkedListMultimap<String, String> params = LinkedListMultimap.create();
String query = uri.getQuery();
if (query != null) {
    for (String param : query.split("&")) {
        String[] kv = param.split("=");
        if (kv.length >= 2) {
            params.put(kv[0], param.substring(kv[0].length() + 1));
        } else {
...
MapparseUriQueryParams(URI uri)
parse Uri Query Params 
Map<String, String> params = new HashMap<String, String>();
String query = uri.getQuery();
if (query == null || query.isEmpty()) {
    return params;
String[] keyValuePairs = query.split(URI_QUERY_PARAM_LINK_CHAR);
for (String kvPair : keyValuePairs) {
    String[] kvSplit = kvPair.split(URI_QUERY_PARAM_KV_CHAR);
...
ArrayListparseURIs(String uri)
parse UR Is 
ArrayList<String> uris = new ArrayList<String>();
int pos = 0;
uris.add(uri);
while (pos < uris.size()) {
    String u = uris.get(pos++);
    Matcher m = uri_param.matcher(u);
    while (m.find()) {
        try {
