Hi Dan,

we use a dedicated HistoryToken class to transparently parse and
manage history tokens. The constructor takes a history token string,
which in our case is supposed to contain a path followed by any number
of URL-style parameters (e.g. index.html#subpath_1/.../subpath_n?
param_1=value_1&...¶m_m=value_m). Excluding getters and setters
(which always return the object so you can concatenate like this:
token = new HistoryToken("myPlace").addToken("mySubPlace").addParam
("param1", "value1") :)) the relevant portion of the class looks like
follows:
public class HistoryToken {
protected String[] subTokens;
protected Map<String, String> parameterMap;
protected String token;
public HistoryToken(String token) {
this.token = token;
parameterMap = new HashMap<String, String>();
if(token == null || token.isEmpty()) {
subTokens = new String[]{};
return;
}
String[] split = token.split("\\?");
subTokens = split[0].split("/");
if(split.length > 1) {
split = split[1].split("&");
for(int i=0; i<split.length; i++) {
String[] params = split[i].split("=");
parameterMap.put(URL.decodeComponent(params[0]),
URL.decodeComponent(params[1]));
}
}
}
public HistoryToken() {
this.token = null;
parameterMap = new HashMap<String, String>();
subTokens = new String[]{};
}
public void buildToken() {
token = "";
for (int i = 0; i < subTokens.length; i++) {
token += subTokens[i];
if(i<subTokens.length-1) token += "/";
}
if(parameterMap.size() > 0) token += "?";
for (Iterator i = parameterMap.entrySet().iterator();
i.hasNext();)
{
Map.Entry<String, String> param = (Map.Entry<String,
String>) i.next
();
token +=
URL.encodeComponent(param.getKey())+"="+URL.encodeComponent
(param.getValue());
if(i.hasNext()) token += "&";
}
}
/* ... ... ... */
}
This approach has thus far worked pretty well for our product :)
Cheers, Jonas
