```
public class HopConfig
extends Object
```
Defines the general configuration for a hop in a tunnel. This is used for both participating tunnels and tunnels we create. Data only stored for tunnels we create should be in TunnelCreatorConfig to save space.

  - HopConfig
```
public HopConfig()
```
    Creates a new HopConfig with default values
- Method Detail
  - getAllocatedBW
```
public int getAllocatedBW()
```
    Get the allocated bandwidth for this hop.
    Returns:
    Bps
  - getAndResetRecentMessagesCount
```
int getAndResetRecentMessagesCount()
```
    This returns the number of processed messages since the last time this was called, and resets the count. It should only be called by code that updates the router stats. See TunnelDispatcher.updateParticipatingStats().
  - getCreation
```
public long getCreation()
```
    when was this tunnel created (in ms since the epoch)?
  - getExpiration
```
public long getExpiration()
```
    when does this tunnel expire (in ms since the epoch)?
  - getIVKey
```
public SessionKey getIVKey()
```
    what key should we use to encrypt the preIV before passing it on?
  - getLayerKey
```
public SessionKey getLayerKey()
```
    what key should we use to encrypt the layer before passing it on?
  - getProcessedMessagesCount
```
public int getProcessedMessagesCount()
```
    Returns:
    the processed messages count
  - getReceiveFrom
```
public Hash getReceiveFrom()
```
    what is the previous peer in the tunnel (null if gateway)
  - getReceiveTunnel
```
public TunnelId getReceiveTunnel()
```
    What tunnel ID are we receiving on? (null if uninitialized)
    Returns:
    the receive tunnel or null
  - getReceiveTunnelId
```
public long getReceiveTunnelId()
```
    What tunnel ID are we receiving on? (0 if uninitialized)
    Returns:
    the receive tunnel ID or 0
  - getRecentMessagesCount
```
public int getRecentMessagesCount()
```
    This returns the number of processed messages since the last time getAndResetRecentMessagesCount() was called. As of 0.9.23, does NOT reset the count, see getAndResetRecentMessagesCount().
    Returns:
    the recent messages count
  - getSendTo
```
public Hash getSendTo()
```
    what is the next peer in the tunnel (null if endpoint)
  - getSendTunnel
```
public TunnelId getSendTunnel()
```
    What is the next tunnel ID we are sending to? (null if endpoint)
    Returns:
    the send tunnel or null
  - getSendTunnelId
```
public long getSendTunnelId()
```
    What is the next tunnel ID we are sending to? (0 if endpoint)
    Returns:
    the send tunnel ID or 0
  - incrementProcessedMessages
```
public void incrementProcessedMessages()
```
    Take note of a message being pumped through this tunnel. "processed" is for incoming and "sent" is for outgoing (could be dropped in between) We use synchronization instead of an AtomicInteger here to save space.
  - setAllocatedBW
```
public void setAllocatedBW(int bw)
```
    Set the allocated bandwidth for this hop.
    Parameters:
    bw - Bps
  - setCreation
```
public void setCreation(long when)
```
    Set the tunnel creation time
  - setExpiration
```
public void setExpiration(long when)
```
    Set the tunnel expiration time
  - setIVKey
```
public void setIVKey(SessionKey key)
```
    Set the IV encryption key
  - setLayerKey
```
public void setLayerKey(SessionKey key)
```
    Set the layer encryption key
  - setReceiveFrom
```
public void setReceiveFrom(Hash from)
```
    Do not set for gateway
    Parameters:
    from - the previous peer hash
  - setReceiveTunnelId
```
public void setReceiveTunnelId(long id)

```
public void setSendTunnelId(TunnelId id)
```
    Set the send tunnel ID. Do not set for endpoint
    Parameters:

```
    Overrides:
    toString in class Object
