Method Detail

apply

public boolean apply(MappedField mappedField,
                     FilterOperator operator,
                     Object value,
                     List<ValidationFailure> validationFailures)

Apply validation for the given operator. If the operator does not match the operator required by the implementing class, then this method will return false to show validation was not applied. If the operator is the one being validated, this method will return true, and any failures in validation will be added to the list of validationFailures.

Parameters:

mappedField - the field being queried

operator - any FilterOperator for a query

value - the query value, to apply the operator to

validationFailures - the list to add any failures to. If validation passes or appliesTo returned false, this list will not change.

Returns:

true if validation was applied, false if this validation doesn't apply to this operator.
