package org.jppf.server.nio.classloader.node

Support for NIO-based communication with the nodes, for the class loader channel. The possible states for these channels, and the possible transitions from these states are as follows:

• WAITING_INITIAL_NODE_REQUEST
  --> WAITING_INITIAL_NODE_REQUEST
  --> SENDING_INITIAL_NODE_RESPONSE
  
  
• SENDING_INITIAL_NODE_RESPONSE
  --> SENDING_INITIAL_NODE_RESPONSE
  --> WAITING_NODE_REQUEST
  
  
• WAITING_NODE_REQUEST
  --> WAITING_NODE_REQUEST
  --> IDLE_NODE
  --> SENDING_NODE_RESPONSE
  
  
• IDLE_NODE
  --> NODE_WAITING_PROVIDER_RESPONSE (by client channel)
