REST Normalizer

This class can validate and filter parameters based on JSON rules.

It can take a list of request parameters passed as an array or as a JSON string and validates it according to rules defined in an external files in the JSON format.

The class can traverse the parameter data and check if the entries match the types and validation rules defined in the rules file for the specific type of request.

Invalid values may be discard and logged to a given log file.

The class may also call callback functions before and after the normalization process.
