Example 1 with AttributeValidator

use of ddf.catalog.validation.AttributeValidator in project ddf by codice.

the class ReportingMetacardValidatorImpl method validateMetacard.

@Override
public Optional<MetacardValidationReport> validateMetacard(final Metacard metacard) {
    Preconditions.checkArgument(metacard != null, "The metacard cannot be null.");
    final Set<ValidationViolation> violations = new HashSet<>();
    for (final AttributeDescriptor descriptor : metacard.getMetacardType().getAttributeDescriptors()) {
        final String attributeName = descriptor.getName();
        final Attribute attribute = metacard.getAttribute(attributeName);
        if (attribute != null) {
            for (final AttributeValidator validator : validatorRegistry.getValidators(attributeName)) {
                validator.validate(attribute).ifPresent(report -> violations.addAll(report.getAttributeValidationViolations()));
            }
        }
    }
    if (violations.size() > 0) {
        return getReport(violations);
    }
    return Optional.empty();
}

Example 2 with AttributeValidator

use of ddf.catalog.validation.AttributeValidator in project ddf by codice.

        left.addAll(right);

    }).orElse(new HashSet<>());
    Set<String> suggestedValues = new HashSet<>();
    Set<ValidationViolation> violations = new HashSet<>();
    for (AttributeValidator validator : validators) {
        Optional<AttributeValidationReport> validationReport = validator.validate(new AttributeImpl(attribute, value));
        if (validationReport.isPresent()) {
            AttributeValidationReport report = validationReport.get();
            if (!report.getSuggestedValues().isEmpty()) {
                suggestedValues = report.getSuggestedValues();
            }
            violations.addAll(report.getAttributeValidationViolations());
        }
