A URL pattern consists of a path pattern, optionally followed by '?' and a list + * of search parameters. Multiple search parameter names are separated by '&'. Search parameters + * do not influence whether or not a URL is matched, but their values are passed through into + * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}. + * + * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace + * syntax, which optionally allows a regular expression for the parameter to be specified: + * + * * `':'` name - colon placeholder + * * `'*'` name - catch-all placeholder + * * `'{' name '}'` - curly placeholder + * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the + * regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash. + * + * Parameter names may contain only word characters (latin letters, digits, and underscore) and + * must be unique within the pattern (across both path and search parameters). For colon + * placeholders or curly placeholders without an explicit regexp, a path parameter matches any + * number of characters other than '/'. For catch-all placeholders the path parameter matches + * any number of characters. + * + * Examples: + * + * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for + * trailing slashes, and patterns have to match the entire path, not just a prefix. + * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or + * '/user/bob/details'. The second path segment will be captured as the parameter 'id'. + * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax. + * * `'/user/{id:[^/]*}'` - Same as the previous example. + * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id + * parameter consists of 1 to 8 hex digits. + * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the + * path into the parameter 'path'. + * * `'/files/*path'` - ditto. + * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined + * in the built-in `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start + * + * @param {string} pattern The pattern to compile into a matcher. + * @param {Object} config A configuration object hash: + * @param {Object=} parentMatcher Used to concatenate the pattern/config onto + * an existing UrlMatcher + * + * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`. + * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`. + * + * @property {string} prefix A static prefix of this pattern.
