Interface TransactionOp

All Known Implementing Classes:

TransactionOp.MapDelete, TransactionOp.MapPut, TransactionOp.MapPutIfAbsent, TransactionOp.MultiMapPut, TransactionOp.MultiMapRemove, TransactionOp.QueueOffer, TransactionOp.QueuePoll, TransactionOp.SetAdd, TransactionOp.SetRemove

public sealed interface TransactionOp
permits TransactionOp.MapPut, TransactionOp.MapDelete, TransactionOp.MapPutIfAbsent, TransactionOp.SetAdd, TransactionOp.SetRemove, TransactionOp.QueueOffer, TransactionOp.QueuePoll, TransactionOp.MultiMapPut, TransactionOp.MultiMapRemove

Sealed interface representing operations that can be buffered in a transaction.

Purpose: TransactionOp is the base type for all transactional operations. Each operation is strongly typed for type safety, efficient pattern matching, and correct serialization across the network.

Design: Uses sealed classes and pattern matching to ensure type safety and enable exhaustive switch expressions during transaction execution.

Operations Supported:

• Map operations: Put, Delete, PutIfAbsent
• Set operations: Add, Remove
• Queue operations: Offer, Poll
• MultiMap operations: Put, Remove

Since:

1.0
