use of com.querydsl.core.types.dsl.CollectionPathBase in project spring-data-commons by spring-projects.

the class PropertyPathInformation method reifyPath.

private static Path<?> reifyPath(EntityPathResolver resolver, PropertyPath path, Optional<Path<?>> base) {
    Optional<Path<?>> map = // 
    base.filter(it -> it instanceof CollectionPathBase).map(CollectionPathBase.class::cast).map(// 
    CollectionPathBase::any).map(// 
    Path.class::cast).map(it -> reifyPath(resolver, path, Optional.of(it)));
    return map.orElseGet(() -> {
        Path<?> entityPath = base.orElseGet(() -> resolver.createPath(path.getOwningType().getType()));
        Field field = org.springframework.data.util.ReflectionUtils.findRequiredField(entityPath.getClass(), path.getSegment());
        Object value = ReflectionUtils.getField(field, entityPath);
        PropertyPath next = path.next();
        if (next != null) {
            return reifyPath(resolver, next, Optional.of((Path<?>) value));
        }
        return (Path<?>) value;
