Method Detail

hasNext

public boolean hasNext()

Description copied from interface: IncrementalExecutionResult

Indicates whether there are pending incremental data.

Specified by:

hasNext in interface IncrementalExecutionResult

Returns:

"true" if there are incremental data, "false" otherwise.

getIncremental

@Nullable
public @Nullable java.util.List<IncrementalPayload> getIncremental()

Description copied from interface: IncrementalExecutionResult

Returns a list of defer and/or stream payloads that the execution engine decided (for whatever reason) to resolve at the same time as the initial payload.

(...)this field may appear on both the initial and subsequent values.

source

Specified by:

getIncremental in interface IncrementalExecutionResult

Returns:

a list of Stream and/or Defer payloads that were resolved at the same time as the initial payload.

getIncrementalItemPublisher

public org.reactivestreams.Publisher<DelayedIncrementalPartialResult> getIncrementalItemPublisher()

Description copied from interface: IncrementalExecutionResult

This method will return a Publisher of deferred results. No field processing will be done until a Subscriber is attached to this publisher.

Once a Subscriber is attached the deferred field result processing will be started and published as a series of events.

Specified by:

getIncrementalItemPublisher in interface IncrementalExecutionResult

Returns:

a Publisher that clients can subscribe to receive incremental payloads.

newIncrementalExecutionResult

public static IncrementalExecutionResultImpl.Builder newIncrementalExecutionResult()

Returns:

a IncrementalExecutionResultImpl.Builder that can be used to create an instance of IncrementalExecutionResultImpl

fromExecutionResult

public static IncrementalExecutionResultImpl.Builder fromExecutionResult(ExecutionResult executionResult)

toSpecification

public java.util.Map<java.lang.String,java.lang.Object> toSpecification()

Description copied from interface: ExecutionResult

The graphql specification says that result of a call should be a map that follows certain rules on what items should be present. Certain JSON serializers may or may interpret ExecutionResult to spec, so this method is provided to produce a map that strictly follows the specification. See : https://spec.graphql.org/October2021/#sec-Response-Format

Specified by:

toSpecification in interface ExecutionResult

Overrides:

toSpecification in class ExecutionResultImpl

Returns:

a map of the result that strictly follows the spec
