#expand(behavior = nil, values = {}) ⇒ String
This method is only implemented by certain subclasses.
Expanding is supported by almost all patterns (notable exceptions are Shell, Regular and Simple).
Union Mustermann::Composite patterns (with the | operator) support expanding if all patterns they are composed of also support it.

#to_templates ⇒ Array<String>
This method is only implemented by certain subclasses.
Generates a list of URI template strings representing the pattern.
Note that this transformation is lossy and the strings matching these templates might not match the pattern (and vice versa).
This comes in quite handy since URI templates are not made for pattern matching. That way you can easily use a more precise template syntax and have it automatically generate hypermedia links for you.
Template generation is supported by almost all patterns (notable exceptions are Shell, Regular and Simple). Union Mustermann::Composite patterns (with the | operator) support template generation if all patterns they are composed of also support it.
