* 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.
