Examples with Optionals org.springframework.data.util.Optionals used on opensource projects

Example 1 with Optionals

use of org.springframework.data.util.Optionals in project spring-data-commons by spring-projects.

the class RepositoryBeanDefinitionBuilder method registerRepositoryFragmentsImplementation.

private Stream<RepositoryFragmentConfiguration> registerRepositoryFragmentsImplementation(RepositoryConfiguration<?> configuration) {
    ClassMetadata classMetadata = getClassMetadata(configuration.getRepositoryInterface());
    RepositoryFragmentDiscovery fragmentConfiguration = new DefaultRepositoryFragmentDiscovery(configuration);
    return // 
    Arrays.stream(classMetadata.getInterfaceNames()).filter(// 
    it -> FragmentMetadata.isCandidate(it, metadataReaderFactory)).map(// 
    it -> FragmentMetadata.of(it, fragmentConfiguration)).map(// 
    it -> detectRepositoryFragmentConfiguration(it, configuration.getConfigurationSource())).flatMap(// 
    Optionals::toStream).peek(// 
    it -> potentiallyRegisterFragmentImplementation(configuration, it)).peek(it -> potentiallyRegisterRepositoryFragment(configuration, it));
}

Example 2 with Optionals

use of org.springframework.data.util.Optionals in project spring-data-commons by spring-projects.

the class CdiRepositoryContext method getRepositoryFragments.

 *
 * @param configuration must not be {@literal null}.
 * @param repositoryInterface must not be {@literal null}.
