Class DroppedTransactionStore

java.lang.Object
nxt.blockchain.DroppedTransactionStore
public class DroppedTransactionStore extends Object
The `DroppedTransactionStore` class handles a collection of comparable data for transactions that have been dropped. It offers functionality to add, retrieve, and clean up entries once the transactions have expired.

This class uses a concurrent map to store known dropped transactions' data and a priority queue to manage its expiration. The priority queue ensures that expired data is cleaned up

The store has a maximum size limit, and if the number of transactions exceeds this limit, the oldest transactions (those closest to expiration) are removed during cleanup.
