Method Details

process

public ProcessorResult process(DictionaryValidationResult result,
 Object value,
 RangeConstraint constraint,
 AttributeValueReader attributeValueReader)
                        throws AttributeValidationException

Description copied from interface: ConstraintProcessor

process the provided constraint

Parameters:

result - - holds dictionary validation results

value - - the value of the attribute

constraint - - the constraint to process

attributeValueReader - - - provides access to the attribute being validated

Returns:

the result of the constraint processing

Throws:

AttributeValidationException

getName

public String getName()

Description copied from interface: ConstraintProcessor

gets a descriptive name of this constraint processor

e.g. @see CollectionSizeConstraintProcessor.CONSTRAINT_NAME

Returns:

a descriptive name

getConstraintType

public Class<? extends Constraint> getConstraintType()

Description copied from interface: ConstraintProcessor

gets the java class type of the constraint that this contraint processor handles

Returns:

an instance of Constraint

processSingleRangeConstraint

protected ConstraintValidationResult processSingleRangeConstraint(DictionaryValidationResult result,
 Object value,
 RangeConstraint constraint,
 AttributeValueReader attributeValueReader)

Parameters:

result - - a holder for any already run validation results

value - - the value to validate

constraint - - the range constraint to use

attributeValueReader - - provides access to the attribute being validated

Returns:

Parameters:

result - - a holder for any already run validation results

value - - the value to validate

constraint - - the range constraint to use

attributeValueReader - - provides access to the attribute being validated

Returns:

the passed in result, updated with the results of the processing

Throws:

IllegalArgumentException

validateRange

protected ConstraintValidationResult validateRange(DictionaryValidationResult result,
 Number value,
 RangeConstraint constraint,
 AttributeValueReader attributeValueReader)
                                            throws IllegalArgumentException

validates the number value using the range constraint provided

Parameters:

result - - a holder for any already run validation results

value - - the value to validate

constraint - - the range constraint to use

attributeValueReader - - provides access to the attribute being validated

Returns:

the passed in result, updated with the results of the processing
