Class AtomicChainsSet<T extends Transaction>

java.lang.Object
nxt.blockchain.atomictxs.AtomicChainsSet<T>
public class AtomicChainsSet<T extends Transaction> extends Object
Set of transactions that tracks the atomic chains formed by the transactions in the set.

The priority order of the chains in the set is according to a comparator provided in the constructor of this class. The highest priority ones are in the beginning of the set, the lowest priority ones are in the end and can be removed with removeLastChain()

Public access is synchronized except from the getAllChains(). Users of this method should synchronize by locking the AtomicChainsSet instance

      public AtomicChainsSet(Comparator<AtomicChain<T>> comparator)
      Construct a new set of atomic chains
      Parameters:
      comparator -

      Order of the chains, the less significant ones being stored last.

      If null, the natural ordering of the AtomicChains is used.

      This comparator must be consistent with equals
