Method

StringconvertToAbsPath(URI baseURI, String path)
convert To Abs Path 
if (path == null || path.isEmpty()) {
    return path;
File absFile = new File(baseURI.resolve(path));
return absFile.getCanonicalPath();
StringconvertToEncodedURIString(String input)
This method replace non-URI-valid characters with their replacement code counterpart (issue PROACTIVE-1314) 
StringBuilder answer = new StringBuilder();
try {
    input = URLDecoder.decode(input, "UTF8");
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
    return null;
char[] inputChars = new char[] { ' ', '\"', '%', '<', '>', '#', '[', '\\', ']', '^', '`', '{', '|', '}' };

URIextractBaseUriFromRDF(String rdfString)
Parses a RDF/XML-serialization and returns the base-URI if a value for 'xml:base' was set, null otherwise. 
int startPos = -1;
int endPos = -1;
startPos = rdfString.indexOf("xml:base=\"") + 10;
if (startPos > 10) {
    endPos = rdfString.indexOf("\"", startPos + 1);
} else {
    startPos = rdfString.indexOf("xmlns=\"") + 7;
    endPos = rdfString.indexOf("\"", startPos + 1) - 1; 
...
MapextractContentDigest(URI contentDigest)
extract Content Digest 
Map<String, String> ret = new HashMap<>();
if (contentDigest != null) {
    final String[] values = contentDigest.getSchemeSpecificPart().split(":");
    if (values.length == 2) {
        ret.put(values[0], values[1]);
return ret;
...
URIextractForwardURIFrom(URI requestURI)
If no forward URI is given then return null. 
int http = requestURI.toString().indexOf("http", 4);
if (http == -1)
    return null;
return URI.create(requestURI.toString().substring(http));
StringextractFromURIParams(String paramsRule, String uri)
Extract and build a dispatch criteria string from URI parameters 
Map<String, String> criteriaMap = new TreeMap<String, String>();
if (uri.contains("?") && uri.contains("=")) {
    String parameters = uri.substring(uri.indexOf("?") + 1);
    for (String parameter : parameters.split("&")) {
        String[] pair = parameter.split("=");
        try {
            String key = URLDecoder.decode(pair[0], "UTF-8");
            String value = URLDecoder.decode(pair[1], "UTF-8");
...
StringextractHostAddress(String uri)
extract Host Address 
URL url = new URL(uri);
return url.getProtocol() + "://" + url.getHost() + ":" + url.getPort();
StringextractHostname(String uri)
extract Hostname 
try {
    return extractHostname(new URI(uri));
} catch (URISyntaxException e) {
    throw new IllegalArgumentException(e);
StringextractLocalName(String uri)
extract Local Name 
return extractLocalName(URI.create(uri));
URIextractOntologyNameUriFromRDF(String rdfString, boolean generateURI)
Parses a RDF/XML-serialization and returns the base-URI if a value for 'xml:base' was set, null otherwise. 
int startPos = -1;
int endPos = -1;
String uri = null;
startPos = rdfString.indexOf("xml:base=\"") + 10;
endPos = rdfString.indexOf("\"", startPos + 1);
uri = rdfString.substring(startPos, endPos);
if (startPos == 9) {
    startPos = rdfString.indexOf("xmlns=\"") + 7;
