- * The host/port combination is specified as followed - *

- * 

- * hostname[:[-]port[-[port]]]
- *
- *

- * The hostname portion can be either a hostname or IP address. If it is - * a hostname, a wildcard is allowed in hostnames. This wildcard is a "*" - * and matches one or more characters. Only one "*" may appear in the - * host and it must be the leftmost character. For example, - * "*.urbanophile.com" matches all hosts in the "urbanophile.com" domain. - *

- * The port portion can be either a single value, or a range of values - * treated as inclusive. The first or the last port value in the range - * can be omitted in which case either the minimum or maximum legal - * value for a port (respectively) is used by default.

  • -4000 - Represents ports 0 through 4000 inclusive
    • - *
  • 1024- - Represents ports 1024 through 65535 inclusive

- * The permission list is a comma separated list of individual permissions. - * These individual permissions are: - *

- * 

- * accept
- * connect
- * listen
- * resolve

- *

- * The "listen" permission is only relevant if the host is localhost. If - * any permission at all is specified, then resolve permission is implied to - * exist. - *

- * SocketPermission("www.urbanophile.com", "connect");

- * SocketPermission("localhost:1024-", "listen,accept,connect");
- *   Can connect to, accept from, an listen on any local port number 1024
- *   and up.
- * SocketPermission("*.edu", "connect");
- *   Can connect to any host in the edu domain
- * SocketPermission("197.197.20.1", "accept");

- * A URI instance represents that defined by - * RFC3986, - * with some deviations. - *

- *

- * At its highest level, a URI consists of: - *

- * [scheme:]scheme-specific-part - * [#fragment] - *

- *

- * where # and : are literal characters, - * and those parts enclosed in square brackets are optional. - *

- *

- * There are two main types of URI. An opaque URI is one - * which just consists of the above three parts, and is not further - * defined. An example of such a URI would be mailto: URI. - * In contrast, hierarchical URIs give further definition - * to the scheme-specific part, so as represent some part of a hierarchical - * structure. - *

- *

- * [//authority][path] - * [?query] - *

- *

- * with / and ? being literal characters. - * When server-based, the authority section is further subdivided into: - *

- *

- * [user-info@]host - * [:port] - *

- *

- * with @ and : as literal characters. - * Authority sections that are not server-based are said to be registry-based. - *

- *

- * Hierarchical URIs can be either relative or absolute. Absolute URIs - * always start with a `/', while relative URIs don't - * specify a scheme. Opaque URIs are always absolute. - *

- *

- * Each part of the URI may have one of three states: undefined, empty - * or containing some content. The former two of these are represented - * by null and the empty string in Java, respectively. - * The scheme-specific part may never be undefined. It also follows from - * this that the path sub-part may also not be undefined, so as to ensure - * the former. - *

- *

Character Escaping and Quoting

- *

- * The characters that can be used within a valid URI are restricted. - * There are two main classes of characters which can't be used as is - * within the URI: - *

- *
    - *
  1. Characters outside the US-ASCII character set. - * These have to be escaped in order to create - * an RFC-compliant URI; this means replacing the character with the - * appropriate hexadecimal value, preceded by a `%'.
    2. - *
  2. Illegal characters (e.g. space characters, - * control characters) are quoted, which results in them being encoded - * in the same way as non-US-ASCII characters.
    3. - *
- *

- * The set of valid characters differs depending on the section of the URI: - *

- *
    - *
  • Scheme: Must be an alphanumeric, `-', `.' or '+'.
    • - *
  • Authority:Composed of the username, host, port, `@' - * and `:'.
    • - *
  • Username: Allows unreserved or percent-encoded - * characters, sub-delimiters and `:'.
    • - *
  • Host: Allows unreserved or percent-encoded - * characters, sub-delimiters and square brackets (`[' and `]') for IPv6 - * addresses.
    • - *
  • Port: Digits only.

  • Path: Allows the path characters and `/'. - *

- * These definitions reference the following sets of characters: - *

    - *
  • Unreserved characters: The alphanumerics plus - * `-', `.', `_', and `~'.
    • - *
  • Sub-delimiters: `!', `$', `&', `(', `)', `*', - * `+', `,', `;', `=' and the single-quote itself.

  • Path characters: Unreserved and percent-encoded - * characters and the sub-delimiters along with `@' and `:'.
    • - *

- * The constructors and accessor methods allow the use and retrieval of - * URI components which contain non-US-ASCII characters directly. - * They are only escaped when the toASCIIString() method - * is used. In contrast, illegal characters are always quoted, with the - * exception of the return values of the non-raw accessors. - *

- * There are a great many protocols supported by URL's such as "http", - * "ftp", and "file". This object can handle any arbitrary URL for which - * a URLStreamHandler object can be written. Default protocol handlers - * are provided for the "http" and "ftp" protocols. Additional protocols - * handler implementations may be provided in the future. In any case, - * an application or applet can install its own protocol handlers that - * can be "chained" with other protocol hanlders in the system to extend - * the base functionality provided with this class. (Note, however, that - * unsigned applets cannot access properties by default or install their - * own protocol handlers). - *

- * This chaining is done via the system property java.protocol.handler.pkgs - * If this property is set, it is assumed to be a "|" separated list of - * package names in which to attempt locating protocol handlers. The - * protocol handler is searched for by appending the string - * ".<protocol>.Handler" to each packed in the list until a hander is - * found. If a protocol handler is not found in this list of packages, or if - * the property does not exist, then the default protocol handler of - * "gnu.java.net.<protocol>.Handler" is tried. If this is - * unsuccessful, a MalformedURLException is thrown. - *

- * All of the constructor methods of URL attempt to load a protocol - * handler and so any needed protocol handlers must be installed when - * the URL is constructed. - *

- * Here is an example of how URL searches for protocol handlers. Assume - * the value of java.protocol.handler.pkgs is "com.foo|com.bar" and the - * URL is "news://comp.lang.java.programmer". URL would looking the - * following places for protocol handlers: - * 

-  * com.foo.news.Handler
-  * com.bar.news.Handler
-  * gnu.java.net.news.Handler
-  *

- * If the protocol handler is not found in any of those locations, a - * MalformedURLException would be thrown. - *

- * Please note that a protocol handler must be a subclass of - * URLStreamHandler. - *

- * Normally, this class caches protocol handlers. Once it finds a handler - * for a particular protocol, it never tries to look up a new handler - * again. However, if the system property - * gnu.java.net.nocache_protocol_handlers is set, then this - * caching behavior is disabled. This property is specific to this - * implementation. Sun's JDK may or may not do protocol caching, but it - * almost certainly does not examine this property. - *

- * Please also note that an application can install its own factory for - * loading protocol handlers (see setURLStreamHandlerFactory). If this is - * done, then the above information is superseded and the behavior of this - * class in loading protocol handlers is dependent on that factory. - * - * @author Aaron M.

Given an array of URLs this class - * loader will retrieve classes and resources by fetching them from - * possible remote locations. Each URL is searched in - * order in which it was added. If the file portion of the - * URL ends with a '/' character then it is interpreted - * as a base directory, otherwise it is interpreted as a jar file from - * which the classes/resources are resolved. - * - *

New instances can be created by two static - * newInstance() methods or by three public - * contructors. Both ways give the option to supply an initial array - * of URLs and (optionally) a parent classloader (that is - * different from the standard system class loader).

- * - *

Normally creating a URLClassLoader throws a - * SecurityException if a SecurityManager is - * installed and the checkCreateClassLoader() method does - * not return true. But the newInstance() methods may be - * used by any code as long as it has permission to acces the given - * URLs. URLClassLoaders created by the - * newInstance() methods also explicitly call the - * checkPackageAccess() method of - * SecurityManager if one is installed before trying to - * load a class. Note that only subclasses of - * URLClassLoader can add new URLs after the - * URLClassLoader had been created. But it is always possible to get - * an array of all URLs that the class loader uses to resolve classes - * and resources by way of the getURLs() method.

- * - *

Open issues: - *

    - * - *
  • Should the URLClassLoader actually add the locations found in - * the manifest or is this the responsibility of some other - * loader/(sub)class? (see - * Extension Mechanism Architecture - Bundles Extensions)
    • - * - *
  • How does definePackage() and sealing work - * precisely?
    • - * - *
  • We save and use the security context (when a created by - * newInstance() but do we have to use it in more - * places?
    • - * - *
  • The use of URLStreamHandlers has not been tested.

- * A URLConnection object is normally created by calling the openConnection() - * method of a URL object. This method is somewhat misnamed because it does - * not actually open the connection. Instead, it return an unconnected - * instance of this object. The caller then has the opportunity to set - * various connection options prior to calling the actual connect() method. - *

- * After the connection has been opened, there are a number of methods in - * this class that access various attributes of the data, typically - * represented by headers sent in advance of the actual data itself. - *

- * Also of note are the getInputStream and getContent() methods which allow - * the caller to retrieve the actual data from the connection. Note that - * for some types of connections, writing is also allowed. The setDoOutput() - * method must be called prior to connecing in order to enable this, then - * the getOutputStream method called after the connection in order to - * obtain a stream to write the output to. - *

- * The getContent() method is of particular note. This method returns an - * Object that encapsulates the data returned.
