Whereas goog.Uri adds several kilobytes to the binary regardless - * of how much of its functionality you use, this is designed to be a set of - * mostly-independent utilities so that the compiler includes only what is - * necessary for the task. Estimated savings of porting is 5k pre-gzip and - * 1.5k post-gzip. To ensure the savings remain, future developers should - * avoid adding new functionality to existing functions, but instead create - * new ones and factor out shared code. - * - * Many of these utilities have limited functionality, tailored to common - * cases. The query parameter utilities assume that the parameter keys are - * already encoded, since most keys are compile-time alphanumeric strings. The - * query parameter mutation utilities also do not tolerate fragment identifiers. - * - * By design, these functions can be slower than goog.Uri equivalents. - * Repeated calls to some of functions may be quadratic in behavior for IE, - * although the effect is somewhat limited given the 2kb limit. - * - * One advantage of the limited functionality here is that this approach is - * less sensitive to differences in URI encodings than goog.Uri, since these - * functions operate on strings directly, rather than decoding them and - * then re-encoding. - * - * Uses features of RFC 3986 for parsing/formatting URIs: - * http://www.ietf.org/rfc/rfc3986.txt - * - * @author gboyer@google.com (Garrett Boyer) - The "lightened" design. - * @author msamuel@google.com (Mike Samuel) - Domain knowledge and regexes. - */ - -goog.provide('goog.uri.utils'); -goog.provide('goog.uri.utils.ComponentIndex'); -goog.provide('goog.uri.utils.QueryArray'); -goog.provide('goog.uri.utils.QueryValue'); -goog.provide('goog.uri.utils.StandardQueryParam'); - -goog.require('goog.array'); -goog.require('goog.asserts'); -goog.require('goog.string'); - - -/** - * Character codes inlined to avoid object allocations due to charCode. - * @enum {number} - * @private - */ -goog.uri.utils.CharCode_ = { - AMPERSAND: 38, - EQUAL: 61, - HASH: 35, - QUESTION: 63 -}; - - -/** - * Builds a URI string from already-encoded parts. - * - * No encoding is performed.
