Constructor Details

ScopeEventingFunctionManager

@Internal
public ScopeEventingFunctionManager(AsyncScopeEventingFunctionManager asyncManager)

Creates a new ScopeEventingFunctionManager.

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

Parameters:

asyncManager - the underlying async manager that performs the ops.

Method Details

upsertFunction

public 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.

Throws:

com.couchbase.client.core.error.EventingFunctionCompilationFailureException - if the function body cannot be compiled.

com.couchbase.client.core.error.CollectionNotFoundException - if the specified collection or scope does not exist.

com.couchbase.client.core.error.BucketNotFoundException - if the specified bucket does not exist.

com.couchbase.client.core.error.EventingFunctionIdenticalKeyspaceException - if the source and metadata keyspace are the same.

com.couchbase.client.core.error.CouchbaseException - if any other generic unhandled/unexpected errors.

upsertFunction

public void upsertFunction(EventingFunction function,
 UpsertFunctionOptions options)
