General Validation library, _(*1)

Overview and structure

The library provides a collection of interfaces and some default implementations for the task of validation., _(*2)

ValidationUtils is an interface of common functions that can be shared through validating classes (typically implementing for example TypeValidation), _(*3)

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)., _(*4)

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., _(*5)

TypeValidation is a general interface for a simple validation., _(*6)

Implementing base class is AbstractTypeValidation, _(*7)
- Common validation functions injected as ValidationUtils interface
- Default values injected as ValidationDefaultValues interface
ArrayValidation, StringValidation etc typically extend AbstractTypeValidation, _(*8)
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., _(*9)

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., _(*10)
