FILTER_PUBLIC_PORT_NAME_CHANGES

public static Predicate<org.apache.nifi.registry.flow.diff.FlowDifference> FILTER_PUBLIC_PORT_NAME_CHANGES

Predicate that returns true if the difference is NOT a name change on a public port (i.e. VersionedPort that allows remote access).

FILTER_ADDED_REMOVED_REMOTE_PORTS

public static Predicate<org.apache.nifi.registry.flow.diff.FlowDifference> FILTER_ADDED_REMOVED_REMOTE_PORTS

Predicate that returns true if the difference is NOT a remote port being added, and false if it is.

FILTER_IGNORABLE_VERSIONED_FLOW_COORDINATE_CHANGES

public static Predicate<org.apache.nifi.registry.flow.diff.FlowDifference> FILTER_IGNORABLE_VERSIONED_FLOW_COORDINATE_CHANGES
