* Value object representing a single route. |

|
|
|
* Routes are a combination of path, middleware, and HTTP methods; two routes |
|
29

|
* representing the same path and overlapping HTTP methods are not allowed, |
|
30
|
|
|

31
|
|
|
* can be used (and should typically resolve to different middleware). |
|
32
|
|
|
* |
|
33
|
|
|
* Internally, only those three properties are required. However, underlying |
|
34
|
|
|
* router implementations may allow or require additional information, such as |
|
35
|
|
|
* information defining how to generate a URL from the given route, qualifiers |
|
36
|
|
|
* for how segments of a route match, or even default values to use. These may |
|
37
|
|
|
* be provided after instantiation via the "defaults" property and related |
|
38
|
|
|
* addDefaults() method. |
