Constructor Detail

DmlFetcher

protected DmlFetcher(String keyspaceName,
                     io.stargate.bridge.proto.Schema.CqlTable table,
                     NameMapping nameMapping)

Method Detail

buildParameters

protected io.stargate.bridge.proto.QueryOuterClass.QueryParameters buildParameters(graphql.schema.DataFetchingEnvironment environment)

buildConditions

protected List<BuiltCondition> buildConditions(Map<String,Map<String,Object>> columnList)

buildClause

protected List<BuiltCondition> buildClause(io.stargate.bridge.proto.Schema.CqlTable table,
                                           graphql.schema.DataFetchingEnvironment environment)

containsDirective

protected boolean containsDirective(graphql.language.OperationDefinition operation,
                                    String directive)

executeAsyncAccepted

protected CompletableFuture<Map<String,Object>> executeAsyncAccepted(io.stargate.bridge.proto.QueryOuterClass.Query query,
                                                                     Object originalValue,
                                                                     StargateGraphqlContext context)

toAcceptedMutationResult

protected com.google.common.collect.ImmutableMap<String,Object> toAcceptedMutationResult(Object originalValue)

Builds the result for a mutation that was annotated with the @async directive. This is fire-and-forget, so we simply reflect back the input value with an additional "accepted=true" field.

toListOfAcceptedMutationResults

protected CompletionStage<List<Map<String,Object>>> toListOfAcceptedMutationResults(List<Map<String,Object>> originalValues)

Same as toAcceptedMutationResult(Object), but for a list of bulk mutations.

toMutationResult

protected Map<String,Object> toMutationResult(io.stargate.bridge.proto.QueryOuterClass.Response response,
                                              Object originalValue)

Builds the result for a regular non-async, non-batched mutation.

toBatchResult

protected Map<String,Object> toBatchResult(io.stargate.bridge.proto.QueryOuterClass.Response response,
                                           Map<String,Object> originalValue)

Builds the result for a mutation that was annotated with the @atomic directive. As a result, it was executed as part of a CQL batch with other mutations.

toBatchResults

protected List<Map<String,Object>> toBatchResults(io.stargate.bridge.proto.QueryOuterClass.Response response,
                                                  List<Map<String,Object>> originalValues)

Same as #toBatchResult(Response, Map), but for a list of bulk mutations.

toGrpcValue

protected io.stargate.bridge.proto.QueryOuterClass.Value toGrpcValue(io.stargate.bridge.proto.QueryOuterClass.TypeSpec type,
                                                                     Object value)

getTtl

protected Integer getTtl(graphql.schema.DataFetchingEnvironment environment)
