utils

Our utils package has all libraries required.

HTML

The library used by our application is the one provided in the shared repository. We've made some significant changes to facilitate it's usage, namely:

• extra elements to Html.java;
• added an extra constructor to HtmlPage.java in order to support css;
• all user inputted data passes through HtmlText.java, so we now escape all strings to reduce ambiguity in reserved characters (like ", <, >, etc) and avoid injection;
• created a new class HtmlRaw.java to input elements with no closing tag.

HTTP

This library is also provided by the shared repository. We've made small changes to it:

• We altered the FormsUrlEncoded.java in order to return the decoded query string untouched instead of returning a map of parameters because that mapping is done by us later in the Parameters.java class;
• Added status 409 Conflict to the class HttpStatusCode.java.

JSON

Similar to html library, this library was provided in one of the shared repositories of previous semesters, it consists in json objects, json arrays, and pair key-value.

• Json.java- base class for this library;
• JsonArray.java - responsible for writing json array syntax [json objects...];
• JsonObject.java - responsible for writing json object syntax {json pair key-value...};
• JsonPairKeyValue.java - responsible for pair key value, separated by ':' ;
• JsonText.java - specific class to write values in json syntax ;

We took advantage of the class Writable.java to use as an interface for our views and created Pair.java to use throughout our application.
