enum class RelevancyStatus
If the querying node is a participant in a state then it is classed as RELEVANT.
If the querying node is not a participant in a state then it is classed as NOT_RELEVANT. These types of states can still be recorded in the vault if the transaction containing them was recorded with the StatesToRecord.ALL_VISIBLE flag. This will typically happen for things like reference data which can be referenced in transactions as a ReferencedStateAndRef but cannot be modified by any party but the maintainer.
If both RELEVANT and NOT_RELEVANT states are required to be returned from a query, then the ALL flag can be used.
NOTE: Default behaviour is for ALL STATES to be returned as this is how Corda behaved before the introduction of this query criterion.
