Class ValidationStateFailureCollector

java.lang.Object

net.sf.mmm.util.validation.base.AbstractValidationStateCollector

net.sf.mmm.util.validation.base.ValidationStateFailureCollector

All Implemented Interfaces:

ValidationCollector, ValidationState

public class ValidationStateFailureCollector
extends AbstractValidationStateCollector

This is an implementation of ValidationState that wraps an existing ValidationState and allows to collect the potential failures for a part of the validation process.
Example:

 public boolean validate(ValidationState state) {
 
   if (state == null) {
     state = new ValidationStateImpl();
   }
 
   ValidationStateFailureCollector failureCollector = new ValidationStateFailureCollector(state);
   validateRecursive(failureCollector);
   List<ValidationFailure> childFailureList = failureCollector.getFailureList();
   if (!childFailureList.isEmpty()) {
     applyValidationFailures(childFailureList);
   }
   return failureCollector.isValid();
 }

3.0.0

Constructor Detail

ValidationStateFailureCollector

public ValidationStateFailureCollector(ValidationState delegate)

The constructor.

Parameters:

delegate - is the ValidationState to adapt.

Method Detail

onFailure

public void onFailure(ValidationFailure failure)

This method gets called if a ValidationFailure occurred.

Specified by:

onFailure in interface ValidationCollector

Overrides:

onFailure in class AbstractValidationStateCollector

Parameters:

failure - is the new ValidationFailure.

isValid

public boolean isValid()

This method determines if the validation has been successful.
ATTENTION:
This method only returns false if a ValidationFailure has been collected by this instance. It may therefore return true even if the delegate would return false.

Specified by:

isValid in interface ValidationState

Overrides:

isValid in class AbstractValidationStateCollector

Returns:

true if no ValidationFailure has been collected, false otherwise.

getFailureList

public List<ValidationFailure> getFailureList()

This method gets the List with the ValidationFailures collected during validation.

Returns:

the List of ValidationFailures.

toString

public String toString()

Overrides:

toString in class Object
