Examples with FieldMask com.google.protobuf.FieldMask used on opensource projects

Example 6 with FieldMask

use of com.google.protobuf.FieldMask in project core-java by SpineEventEngine.

the class QueryBuilder method build.

/**
     * Generates a new instance of {@link Query} regarding all the set parameters.
     *
     * @return the built {@link Query}
     */
public Query build() {
    final FieldMask mask = composeMask();
    // Implying AnyPacker.pack to be idempotent
    final Set<Any> entityIds = composeIdPredicate();
    final Query result = queryFactory.composeQuery(targetType, entityIds, columns, mask);
    return result;
}

Example 7 with FieldMask

use of com.google.protobuf.FieldMask in project core-java by SpineEventEngine.

the class QueryFactory method byIdsWithMask.

/**
     * Creates a {@link Query} to read certain entity states by IDs with the {@link FieldMask}
     * applied to each of the results.
     *
     * <p>Allows to specify a set of identifiers to be used during the {@code Query} processing.
     * The processing results will contain only the entities, which IDs are present among
     * the {@code ids}.
     *
     * <p>Allows to set property paths for a {@link FieldMask}, applied to each of the query
     * results. This processing is performed according to the
     * <a href="https://goo.gl/tW5wIU">FieldMask specs</a>.
     *
     * <p>In case the {@code paths} array contains entries inapplicable to the resulting entity
     * (e.g. a {@code path} references a missing field),
     * such invalid paths are silently ignored.
     *
     * @param entityClass the class of a target entity
     * @param ids         the entity IDs of interest
     * @param maskPaths   the property paths for the {@code FieldMask} applied
     *                    to each of results
     * @return an instance of {@code Query} formed according to the passed parameters
     */
