Interface Summary

Interface	Description
Flow	A reference to the Flow object attached to the current invocation context.
FlowFuture<T>	This class exposes operations (with a similar API to CompletionStage) that allow asynchronous computation to be chained into the current execution graph of a Flow.
Flows.FlowSource	Defines a supplier for the current runtime-
Flows.SerBiConsumer<T,U>	Version of BiConsumer that is implicitly serializable.
Flows.SerBiFunction<T,U,R>	Version of BiFunction that is implicitly serializable.
Flows.SerCallable<V>	Version of Callable that is implicitly serializable.
Flows.SerConsumer<V>	Version of Consumer that is implicitly serializable.
Flows.SerFunction<T,V>	Version of Function that is implicitly serializable.
Flows.SerRunnable	Version of Runnable that is implicitly serializable.
Flows.SerSupplier<V>	Version of Supplier that is implicitly serializable.
HttpRequest	An abstract HTTP request details (without location)
HttpResponse	A FunctionResponse represents the HTTP response from an external function invocation (e.g.

Class Summary

Class	Description
Flows	Fn Flow API entry point class - this provides access to the current Flow for the current function invocation.

Enum Summary

Enum	Description
Flow.FlowState	Represents the possible end states of a Flow object, i.e.
HttpMethod	Enum representing the different HTTP types that can be used to invoke an external function

Exception Summary

Exception	Description
FlowCompletionException	Exception thrown when a blocking operation on a flow fails - this corresponds to a CompletionException in CompletableFuture calls
FunctionInvocationException	Exception thrown when an external function invocation returns a failure.
FunctionInvokeFailedException	Exception thrown when a function call failed within the fn platform - the function may or may not have been invoked and that invocation may or may not have completed.
FunctionTimeoutException	Exception thrown when a function execution exceeds its configured timeout.
InvalidStageResponseException	Exception thrown when a completion stage responds with an incompatible datum type for its corresponding completion graph stage.
LambdaSerializationException	Exception thrown when a lambda or any referenced objects fail to be serialized.
PlatformException	Exception thrown when the completion facility fails to operate on a completion graph
ResultSerializationException	Exception thrown when a result returned by a completion stage fails to be serialized.
StageInvokeFailedException	Exception thrown when a a completion stage invocation failed within Fn - the stage may or may not have been invoked and that invocation may or may not have completed.
StageLostException	Exception thrown when a stage failed after an internal error in the flow server, the stage may or may not have been invoked and that invocation may or may not have completed.
StageTimeoutException	Exception thrown when a completion stage function execution exceeds it configured timeout - the stage may or may not have completed normally.
WrappedFunctionException	Wrapped exception where the root cause of a function failure was not serializable.
