Constructor Details

ReactiveEventingFunctionManager

@Internal
public ReactiveEventingFunctionManager(AsyncEventingFunctionManager asyncManager)

Creates a new ReactiveEventingFunctionManager.

This API is not intended to be called by the user directly, use ReactiveCluster.eventingFunctions() instead.

Parameters:

asyncManager - the underlying async manager that performs the ops.

Method Details

upsertFunction

public Mono<Void> upsertFunction(EventingFunction function)

Inserts or replaces a EventingFunction.

The eventing management API defines that if a function is stored which name does not exist yet, it will be inserted. If the name already exists, the function will be replaced with its new equivalent and the properties changed.

Operations which change the runtime-state of a function (i.e. deploy / undeploy / pause / resume) should not be modified through this method, but rather by using those methods directly (i.e. deployFunction(String)).

Parameters:

function - the function to be inserted or replaced.

Returns:

a Mono completing when the operation is applied or failed with an error.

Throws:

EventingFunctionCompilationFailureException - (async) if the function body cannot be compiled.

CollectionNotFoundException - (async) if the specified collection or scope does not exist.

BucketNotFoundException - (async) if the specified bucket does not exist.

EventingFunctionIdenticalKeyspaceException - (async) if the source and metadata keyspace are the same.

CouchbaseException - (async) if any other generic unhandled/unexpected errors.
