      • getConstraintMoniker

        java.lang.String getConstraintMoniker()

        UUID getBackingIndexUUID()
        Allocates a UUID if one doesn't already exist for the index backing this constraint. This allows Replication logic to agree with the core compiler on what the UUIDs of indices are.

        a UUID for the constraint. allocates one if this is the first time this method is called.

      • getBackingIndexName
