+ * Methods for an OAuth consumer to request tokens from a service provider.
+ * <p>
+ * This class can also be used to request access to protected resources, in some
+ * cases. But not in all cases. For example, this class can't handle arbitrary
+ * HTTP headers.
+ * <p>
+ * Methods of this class return a response as an OAuthMessage, from which you
+ * can get a body or parameters but not both. Calling a getParameter method will
+ * read and close the body (like readBodyAsString), so you can't read it later.
+ * If you read or close the body first, then getParameter can't read it. The
+ * response headers should tell you whether the response contains encoded
+ * parameters, that is whether you should call getParameter or not.
+ * <p>
+ * Methods of this class don't follow redirects. When they receive a redirect
+ * response, they throw an OAuthProblemException, with properties
+ * HttpResponseMessage.STATUS_CODE = the redirect code
+ * HttpResponseMessage.LOCATION = the redirect URL. Such a redirect can't be
+ * handled at the HTTP level, if the second request must carry another OAuth
+ * signature (with different parameters). For example, Google's Service Provider
+ * routinely redirects requests for access to protected resources, and requires
+ * the redirected request to be signed.

+ *
+ * A service provider that wishes to verify signatures made by such a
+ * consumer does not need a shared secret with the consumer, but it needs

+ * public key. You create the necessary OAuthConsumer object (on the service
+ * provider's side) like this:
+ *
+ * OAuthConsumer c = new OAuthConsumer(callback_url, consumer_key,

+ *
+ * consumer_cert must be a X509 Certificate containing the consumer's public

+// Autocompleter.Base handles all the autocompletion functionality
+// that's independent of the data source for autocompletion. This
+// includes drawing the autocompletion menu, observing keyboard
+// and mouse events, and similar.
+//
+// Specific autocompleters need to provide, at the very least,
+// a getUpdatedChoices function that will be invoked every time
+// the text inside the monitored textbox changes. This method
+// should get the text for which to provide autocompletion by
+// invoking this.getToken(), NOT by directly accessing
+// this.element.value. This is to allow incremental tokenized
+// autocompletion. Specific auto-completion logic (AJAX, etc)
+// belongs in getUpdatedChoices.
+//
+// Tokenized incremental autocompletion is enabled automatically
+// when an autocompleter is instantiated with the 'tokens' option
+// in the options parameter, e.g.:
+// new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
+// will incrementally autocomplete with a comma as the token.
+// Additionally, ',' in the above example can be replaced with
+// a token array, e.g. { tokens: [',', '\n'] } which
+// enables autocompletion on multiple tokens. This is most
+// useful when one of the tokens is \n (a newline), as it
+// allows smart autocompletion after linebreaks.

+// The third is the array you want to autocomplete from, and the fourth
+// is the options block.
+//
+// Extra local autocompletion options:
+// - choices - How many autocompletion choices to offer
+//
+// - partialSearch - If false, the autocompleter will match entered
+// text only at the beginning of strings in the
+// autocomplete array. Defaults to true, which will
+// match text at the beginning of any *word* in the
+// strings in the autocomplete array. If you want to
+// search anywhere in the string, additionally set
+// the option fullSearch to true (default: off).
+//
+// - fullSsearch - Search anywhere in autocomplete array strings.
+//
+// - partialChars - How many characters to enter before triggering
+// a partial match (unlike minChars, which defines
+// how many characters are required to do any match
+// at all). Defaults to 2.
+//
+// - ignoreCase - Whether to ignore case when autocompleting.
+// Defaults to true.
