Nyx
Nyx Collections is an experimental Java library that offers an implementation of standard Java Collections API with collection elements allocated in the off-heap memory. It is designed to support an XL-size collections which makes it ideal choice for implementing memory and computationally intensive applications.
###Features
- Thread-safe high-speed implementation of List, Set, Map and Queue collections with data elements allocated in off-heap memory.
- Specifically designed for XL size collections it ensures high throughput and memory conservation.
- Extended Nyx Collections API allows for easy and efficient implementation of various computation scenarios with operations like #foreach, #filter, #mapTo.
###Examples
/* Create Nyx List collection */
List<MyObject> nyx = new NyxList<>();
/* Filters out null elements */
List<Integer> list1 = Fn.on(list).filter(Fn.<Integer>notNull()).get();
/* Filters out elements outside given range */
list1 = Fn.on(list1).filter(Fn.<Integer>range(0, 5)).get();
/* A field of an anonymous class can be used to accumulate and return computation result */
int sum = Fn.on(list1).forEach(new Fn.NoRet<Integer>() {
int counter = 0;
@Override public void func(Integer t) { counter += t; }
}).counter;
Requirements
Nyx collections can be used with Java 9/10 platform.
