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.
