Class ListChain<T>

java.lang.Object

oracle.ucp.util.ListChain<T>

Type Parameters:

T - type of a chain element

All Implemented Interfaces:

Chain<T>

public class ListChain<T>
extends Object
implements Chain<T>

Thread-safe stack chain with effectively removable handled atoms from the middle of a chain. Atom addition works like in a stack. Atom removal works like in a double linked list: it is possible to quickly remove any atom from any position, it is just enough to have it's handle, it is not necessary to even have a chain itself (an atom internally refers to a chain). TODO - this class is a candidate for further optimization: it would be nice to lock fragments of a chain (instead of locking a whole one) while adding/removing atoms. That way this class is going to be handled even faster.
