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

Example 1 with EntityValue

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

the class TwoStepsConversions method applyEntityValueBuilder.

private EntityValue applyEntityValueBuilder(Object val, String kindName, Consumer<Builder> consumer, boolean createKey) {
    FullEntity.Builder<IncompleteKey> builder;
    if (!createKey) {
        builder = FullEntity.newBuilder();
    } else {
        /* The following does 3 sequential null checks. We only want an ID value if the object isn't null,
				has an ID property, and the ID property isn't null.
			* */
        Optional idProp = Optional.ofNullable(val).map(v -> this.datastoreMappingContext.getPersistentEntity(v.getClass())).map(datastorePersistentEntity -> datastorePersistentEntity.getIdProperty()).map(id -> this.datastoreMappingContext.getPersistentEntity(val.getClass()).getPropertyAccessor(val).getProperty(id));
        IncompleteKey key = idProp.isPresent() ? this.objectToKeyFactory.getKeyFromId(idProp.get(), kindName) : this.objectToKeyFactory.getIncompleteKey(kindName);
        builder = FullEntity.newBuilder(key);
    }
    consumer.accept(builder);
    return EntityValue.of(builder.build());
}

Example 2 with EntityValue

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