MvcPropertyMappingConfigurationService
class MvcPropertyMappingConfigurationService (View source)
This is a Service which can generate a request hash and check whether the currently given arguments fit to the request hash.
It is used when forms are generated and submitted: After a form has been generated, the method "generateRequestHash" is called with the names of all form fields. It cleans up the array of form fields and creates another representation of it, which is then serialized and hashed.
Both serialized form field list and the added hash form the request hash, which will be sent over the wire (as an argument __hmac).
On the validation side, the validation happens in two steps: 1) Check if the request hash is consistent (the hash value fits to the serialized string) 2) Check that all GET/POST parameters submitted occur inside the form field list of the request hash.
Note: It is crucially important that a private key is computed into the hash value! This is done inside the HashService.

Methods
Generate a request hash for a list of form fields
Serialize and hash the form field array
Initialize the property mapping configuration in $controllerArguments if the trusted properties are set inside the request.
Modify the passed $propertyMappingConfiguration according to the $propertyConfiguration which has been generated by e.g. Fluid. In detail, if the $propertyConfiguration contains an __identity field, we allow modification of objects; else we allow creation.
