fkConstraintNames
- the foreign key constraint namesschemaName
- the name of the schema of the table being modifiedtableName
- the name of the table being modifiedstmtType
- the type of the statement: e.g. StatementType.INSERTtype
- either FKInfo.REFERENCED_KEY or FKInfo.FOREIGN_KEYrefUUID
- UUID of the referenced constraint's supporting indexrefConglomNumber
- conglomerate number of the referenced keyrefConstraintID
- UUID of the referenced constraintrefConstraintIsDeferrable
- true
iff the referenced key
constraint is deferrablefkUUIDs
- an array of fkUUIDs of backing indexes. if
FOREIGN_KEY, then just one element, the backing
index of the referenced keys. if REFERENCED_KEY,
then all the foreign keysfkConglomNumbers
- array of conglomerate numbers, corresponds
to fkUUIDsfkIsSelfReferencing
- array of conglomerate booleans indicating
whether the foreign key references a key in the same tablecolArray
- map of columns to the base row that DML
is changing. 1 based. Note that this maps the
constraint index to a row in the target table of
the current DML operation.rowLocation
- a row location template for the target table
used to pass in a template row to tc.openScan()raRules
- referential action rulesdeferrable
- the corresponding constraint is deferrablefkIds
- the foreign key constraints' uuids.public static FKInfo[] chooseRelevantFKInfos(FKInfo[] fkInfo, int[] cols, boolean addAllTypeIsFK)
