- - net.i2p.router.dummy.VMCommSystem

All Implemented Interfaces:

Service
```
public class VMCommSystem
extends CommSystemFacade
```
Hacked up in-VM comm system for talking between contexts. It doesn't even generate any routerAddresses, but instead tracks the peers through a singleton. Currently, the comm system doesn't even inject any lag, though it could (later). It does honor the standard transport stats though, but not the TCP specific ones. FOR DEBUGGING AND LOCAL TESTING ONLY.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`countActivePeers()`	How many peers are we currently connected to, that we have sent a message to or received a message from in the last five minutes.
`int`	`countActiveSendPeers()`	How many peers are we currently connected to, that we have sent a message to in the last minute.
`Set<Hash>`	`getEstablished()`	Get all the peers we are connected to.
`boolean`	`isEstablished(Hash peer)`
`void`	`processMessage(OutNetMessage msg)`	The router wants us to send the given message to the peer.
`void`	`receive(byte[] message, Hash fromPeer)`	We send messages between comms as bytes so that we strip any router-local info.
`void`	`renderStatusHTML(Writer out, String urlBase, int sortFlags)`
`void`	`restart()`	Perform a soft restart.
`void`	`shutdown()`	Instruct the service that the router is shutting down and that it should do whatever is necessary to go down gracefully.
`void`	`startup()`	Instruct the service that it should start normal operation.

```
public VMCommSystem(RouterContext context)
```
- Method Detail
  - countActivePeers
```
public int countActivePeers()
```
    Description copied from class: CommSystemFacade
    
    How many peers are we currently connected to, that we have sent a message to or received a message from in the last five minutes.
    
    Specified by:
    
    countActivePeers in class CommSystemFacade
  - countActiveSendPeers
```
public int countActiveSendPeers()
```
    Description copied from class: CommSystemFacade
    
    How many peers are we currently connected to, that we have sent a message to in the last minute. Unused for anything, to be removed.
    
    Specified by:
    
    countActiveSendPeers in class CommSystemFacade
  - isEstablished
```
public boolean isEstablished(Hash peer)
```
    Specified by:
    
    isEstablished in class CommSystemFacade
  - getEstablished
```
public Set<Hash> getEstablished()
```
    Description copied from class: CommSystemFacade
    
    Get all the peers we are connected to. This should be more efficient than repeated calls to isEstablished() if you have to check a lot.
    
    Specified by:
    
    getEstablished in class CommSystemFacade
    
    Returns:
    
    the hashes of all the routers we are connected to, non-null
  - processMessage
```
public void processMessage(OutNetMessage msg)
```
    The router wants us to send the given message to the peer. Do so, or fire off the failing job.
    
    Specified by:
    
    processMessage in class CommSystemFacade
  - receive
```
public void receive(byte[] message,
                    Hash fromPeer)
```
    We send messages between comms as bytes so that we strip any router-local info. For example, a router tags the # attempts to send through a leaseSet, what type of tunnel a tunnelId is bound to, etc.
  - shutdown
```
public void shutdown()
```
    Description copied from interface: Service
    
    Instruct the service that the router is shutting down and that it should do whatever is necessary to go down gracefully. It should not depend on other components at this point. This call DOES block.
  - startup
```
public void startup()
```
    Description copied from interface: Service
    
    Instruct the service that it should start normal operation. This call DOES block until the service is ready.
  - restart
```
public void restart()
```
    Description copied from interface: Service
    
    Perform a soft restart.
  - renderStatusHTML
```
public void renderStatusHTML(Writer out,
                             String urlBase,
                             int sortFlags)
                      throws IOException
```
    Overrides:
    
    renderStatusHTML in class CommSystemFacade
    
    Throws:
    
    IOException
