Interface KryoPool

public interface KryoPool

A simple pool interface for Kryo instances. Use the KryoPool.Builder to construct a pool instance. Usage:

 import com.esotericsoftware.kryo.Kryo;
 import com.esotericsoftware.kryo.pool.*;
 
 KryoFactory factory = new KryoFactory() {
   public Kryo create () {
     Kryo kryo = new Kryo();
     // configure kryo instance, customize settings
     return kryo;
   }
 };
 // Simple pool, you might also activate SoftReferences to fight OOMEs.
 KryoPool pool = new KryoPool.Builder(factory).build();
 Kryo kryo = pool.borrow();
 // do s.th. with kryo here, and afterwards release it
 pool.release(kryo);
 
 // or use a callback to work with kryo (pool.run borrows+releases for you)
 String value = pool.run(new KryoCallback() {
   public String execute(Kryo kryo) {
     return kryo.readObject(input, String.class);
   }
 });
