    Constructor to set the performative to Performative.REQUEST.
  - public ReservationReq(AgentID recipient)
    
    Constructor to specify the agent which provides Services.MAC.
    Parameters:
    recipient - AgentID.
- Method Detail
  - public float getDuration()
    
    Gets the duration for which the channel will be reserved (in seconds).
    Returns:
    duration
  - public byte[] getPayload()
    
    Gets the payload information in byte[].
    Returns:
    payload information in byte[]
  - public Priority getPriority()
    
    Gets the priority of the reservation request.
    Returns:
    priority
  - public Long getStartTime()
    
    Gets the starting time for the reservation request. The time is in microseconds according to the Physical agent's clock.
    Returns:
    starting time in microseconds, or null if no specified starting time.

    org.arl.unet.phy.PhyscialParam
  - public int getTo()
    
    Gets the NodeInfoParam.address of the destination node.
    Returns:
    to address
  - public float getTtl()
    
    Gets the time-to-live for the reservation request.
    Returns:
    time-to-live, NaN if none defined.
  - public boolean isReliable()
    
    Gets the value of reliable.
    Returns:
    reliable
  - public void setDuration(float duration)
    
    Sets the duration for which the channel will be reserved, with the destination (in seconds).
    Parameters:
    duration - in milliseconds
  - public void setPayload(byte[] payload)
    
    Sets payload with meta information(in a byte[]), that the TX client agent communicates with RX node.
    Parameters:
    payload - info in byte[]
  - public void setPriority(Priority priority)
    
    Sets the priority of the reservation request. A priority are advisory, and an underlying agent may choose to ignore it, if it does not support prioritization.
    Parameters:
    priority - priority assigned to the request.
  - public void setReliable(boolean reliable)
    
    Sets value to specify if current reservation requires reliability (in the form of mac layer acknowledgements), if supported by the underlying MAC agent.
    Parameters:
    reliable - value to set/unset mac layer acknowledgements
  - public void setStartTime(Long time)
    
    Sets the starting time for the reservation request. The time is in microseconds according to the Physical agent's clock.
    Parameters:
    time - starting time in microseconds, or null to disable starting time.

  - public void setTo(int to)
    
    Sets the address of the destination node.
    Parameters:
    to - destination address
  - public void setTtl(float ttl)
    
    Sets the time-to-live for the reservation request. Time-to-live is advisory, and an agent may choose it ignore it. If a reservation request is dropped, a ReservationStatusNtf indicating a FAILURE must be sent for that request.
    Parameters:
    ttl - time-to-live or NaN if no limit defined.
