Examples with BaseEntity com.google.cloud.datastore.BaseEntity used on opensource projects

Example 1 with BaseEntity

use of com.google.cloud.datastore.BaseEntity in project spring-cloud-gcp by spring-cloud.

the class DatastoreTemplate method convertEntityResolveDescendantsAndReferences.

private <T> T convertEntityResolveDescendantsAndReferences(Class<T> entityClass, DatastorePersistentEntity datastorePersistentEntity, BaseKey key, ReadContext context) {
    T convertedObject;
    if (context.converted(key)) {
        convertedObject = (T) context.getConvertedEntity(key);
    } else {
        BaseEntity readEntity = context.getReadEntity(key);
        convertedObject = this.datastoreEntityConverter.read(entityClass, readEntity);
        // the parent entity should be put into context BEFORE referenced and descendant entities
        // are being resolved to avoid infinite loops
        context.putConvertedEntity(key, convertedObject);
        // raw Datastore entity is no longer needed
        context.removeReadEntity(key);
        if (convertedObject != null) {
            resolveDescendantProperties(datastorePersistentEntity, readEntity, convertedObject, context);
            resolveReferenceProperties(datastorePersistentEntity, readEntity, convertedObject, context);
        }
    }
    return convertedObject;
}

Example 2 with BaseEntity

use of com.google.cloud.datastore.BaseEntity in project spring-cloud-gcp by spring-cloud.

the class GqlDatastoreQuery method getNonEntityObjectFromRow.

private static Object getNonEntityObjectFromRow(Object x) {
    Object mappedResult;
    if (x instanceof Key) {
        mappedResult = x;
    } else {
        BaseEntity entity = (BaseEntity) x;
        Set<String> colNames = entity.getNames();
        if (colNames.size() > 1) {
            throw new DatastoreDataException("The query method returns non-entity types, but the query result has " + "more than one column. Use a Projection entity type instead.");
        }
        mappedResult = entity.getValue((String) colNames.toArray()[0]).get();
    }
    return mappedResult;
