/**
|
|
* Matches URLs against patterns and extracts named parameters from the path or the search
|
|
* part of the URL. 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 UrlMatcher#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 '}' - curly placeholder with regexp. 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.
|
|
*
|
|
* @constructor
|
|
* @param {string} pattern the pattern to compile into a matcher.
|
|
*
|
|
* @property {string} prefix A static prefix of this pattern. The matcher guarantees that any
|
|
* URL matching this matcher (i.e. any string for which {@link UrlMatcher#exec exec()} returns
|
|
* non-null) will start with this prefix.
