* Stores all metadata needed for validating a class property via its getter

|
|
* A property getter is any method that is equal to the property's name,
|
|
* prefixed with "get", "is" or "has". That method will be used to access the
|
|
* property's value.
|
|
*
|

* The getter will be invoked by reflection, so the access of private and
|
|
* protected getters is supported.
|
|
*
|
|
* This class supports serialization and cloning.
