Arpad Boda created MINIFICPP-1457:
-------------------------------------
Summary: Implement InputRequirements
Key: MINIFICPP-1457
URL: https://issues.apache.org/jira/browse/MINIFICPP-1457
Project: Apache NiFi MiNiFi C++
Issue Type: New Feature
Reporter: Arpad Boda
InputRequirements already exist in NiFi.
Processors can have the following "annotations":
{code}
enum Requirement {
/**
* This value is used to indicate that the Processor requires input
from other Processors
* in order to run. As a result, the Processor will not be valid if it
does not have any
* incoming connections.
*/
INPUT_REQUIRED,
/**
* This value is used to indicate that the Processor will consume data
from an incoming
* connection but does not require an incoming connection in order to
perform its task.
* If the {@link InputRequirement} annotation is not present, this is
the default value
* that is used.
*/
INPUT_ALLOWED,
/**
* This value is used to indicate that the Processor is a "Source
Processor" and does
* not accept incoming connections. Because the Processor does not pull
FlowFiles from
* an incoming connection, it can be very confusing for users who
create incoming connections
* to the Processor. As a result, this value can be used in order to
clarify that incoming
* connections will not be used. This prevents the user from even
creating such a connection.
*/
INPUT_FORBIDDEN;
}
{code}
Should be used both in yaml config validation and population of C2 manifest
