A coercion function that coerces the array of result (i.e. output argument) values of the OPC UA method call to the result value of the associated Return event (optional).
If not specified, a default coercion takes place: If the array of output
argument values contains just a single value, this value is passed as a
result value. If the array of output argument values is empty,
undefined is passed as result value. Otherwise, the array of output
argument values is passed unchanged.
If the coercion function throws an error, a Return event with a "Bad OPC UA method call" error (error code 1) is published.
An array of mappings for OPC UA method input arguments associated with specific Call event parameters.
The order of mappings must mirror the order of OPC UA input arguments. Superfluous Call event parameters are ignored. If input argument mappings for unknown Call event parameters are specified, the associated OPC UA method is not invoked and a Return event with an InvalidParameters error is published.
The name of the Call event operation to be mapped to an OPC UA method call.
The operation context to be matched against the context filter of the Call event (optional).

Defines a one-to-one mapping from a Call-Return event operation to an OPC UA method call.
