Class SimpleContainer

java.lang.Object
  grinda.impl.tuplespace.SimpleContainer

All Implemented Interfaces:

TupleContainer

public class SimpleContainer
extends java.lang.Object
implements TupleContainer

This is a simple implementation of a TupleContainer using a vector to store objects. It is used instead of the HashContainer to store few tuples with better memory consumption.
