Examples with AtlasConverter io.atlasmap.spi.AtlasConverter used on opensource projects

Example 1 with AtlasConverter

use of io.atlasmap.spi.AtlasConverter in project atlasmap by atlasmap.

the class DefaultAtlasConversionServiceTest method findMatchingConverterByFieldTypes.

@Test
public void findMatchingConverterByFieldTypes() {
    assertNotNull(service);
    Optional<AtlasConverter<?>> atlasConverter = service.findMatchingConverter(FieldType.STRING, FieldType.BOOLEAN);
    assertTrue(atlasConverter.isPresent());
    assertNotNull(atlasConverter);
    assertEquals(StringConverter.class, atlasConverter.get().getClass());
    StringConverter stringConverter = (StringConverter) atlasConverter.get();
    assertNotNull(stringConverter);
    assertEquals("io.atlasmap.converters.StringConverter", atlasConverter.get().getClass().getCanonicalName());
    Boolean t = stringConverter.toBoolean("T", null, null);
    assertNotNull(t);
    assertTrue(t);
    Boolean f = stringConverter.toBoolean("F", null, null);
    assertNotNull(f);

    FieldType fieldType = null;
    service.findMatchingConverter(fieldType, fieldType);
}

Example 2 with AtlasConverter

use of io.atlasmap.spi.AtlasConverter in project atlasmap by atlasmap.

the class JavaMappingFieldPairValidator method validateClassConversion.

private void validateClassConversion(String mappingId, JavaField inputField, JavaField outField, List<Validation> validations) {
    // skip converter check for COMPLEX source field (possible for conditional mapping)
    if (inputField.getFieldType() == FieldType.COMPLEX) {
        return;
    }
    Optional<AtlasConverter<?>> atlasConverter = conversionService.findMatchingConverter(inputField.getClassName(), outField.getClassName());
    if (!atlasConverter.isPresent()) {
        Validation validation = new Validation();
        validation.setScope(ValidationScope.MAPPING);
        validation.setId(mappingId);
        validation.setMessage(String.format("Conversion from '%s' to '%s' is required but no converter is available", inputField.getClassName(), outField.getClassName()));

        validations.add(validation);
    } else {
        AtlasConversionInfo conversionInfo;

        Method[] methods = atlasConverter.get().getClass().getMethods();
        conversionInfo = Arrays.stream(methods).map(method -> method.getAnnotation(AtlasConversionInfo.class)).filter(atlasConversionInfo -> atlasConversionInfo != null).filter(atlasConversionInfo -> atlasConversionInfo.sourceType().compareTo(inputField.getFieldType()) == 0 && atlasConversionInfo.targetType().compareTo(outField.getFieldType()) == 0).findFirst().orElse(null);
        if (conversionInfo != null) {
            populateConversionConcerns(validations, mappingId, conversionInfo, service.getModuleFieldName(inputField), service.getModuleFieldName(outField));
        }
    }
