General Validation library

Overview and structure

The library provides a collection of interfaces and some default implementations for the task of validation.

ValidationUtils is an interface of common functions that can be shared through validating classes (typically implementing for example TypeValidation)

ValidationDefaultValues is an interface providding a list of default values for validation constraints so if the constraint x is not set for field y, the constraint x will be validated against default value for field y (this way only the values differing from default need to be confed).

• ValidationDefaultValuesImpl is an implementing class that takes it's values from ini file that is injected as a path to constructor of the class.

ValidationCollection is a collection of TypeValidations.

TypeValidation is a general interface for a simple validation.

• Implementing base class is AbstractTypeValidation

• • Common validation functions injected as ValidationUtils interface
• • Default values injected as ValidationDefaultValues interface

• ArrayValidation, StringValidation etc typically extend AbstractTypeValidation

• GeneralValidation is an implementation that coordinates a group of TypeValidation implementations injected to it in ValidationCollection through constructor. The TypeValidation implementation of given type is used for validating, unless not defined whereas the default type is used.

Validation is a general interface for taking an array of fields and validating them with constructor injected TypeValidation against the field constraint configuration also injected into constructor.

Example usage

Contribution guidelines

• Implementation classes must be unit tested
