Class ValidationEngine

java.lang.Object

com.latitude.validator.spi.impl.ValidationEngine

All Implemented Interfaces:

ValidationOperations

public class ValidationEngine
extends Object
implements ValidationOperations

This class represents a template to execute the validation process. Holds a set of Validator objects able to verify the requirements necessary for a subject to be valid.

When the validation is performed, is elected the first validator able to apply the validation logic for the subject in input and the validation is delegated to the latter. If a ValidationException is thrown, by default, the validation process ends with an ExitStatus.FAILED, ExitStatus.COMPLETED otherwise.

A "non-strict" mode can be activated to allow anyway the execution of all the Validators in the validation chain even if a ValidationException is thrown.
