Message (I2P Anonymous Network - Java Documentation - Version 1.5.0)

java.lang.Object
- edu.internet2.ndt.Message

```
public class Message
extends Object
```
Class to define Message. Messages are composed of a "type" and a body. Some examples of message types are : COMM_FAILURE, SRV_QUEUE, MSG_LOGIN, TEST_PREPARE. Messages are defined to have a "length" field too. Currently, 2 bytes of the message "body" byte array are often used to store length (For example, second/third array positions)
TODO for a later release: It may be worthwhile exploring whether MessageTypes could be merged here instead of being located in NDTConstants. Message/Type could also be made into an enumeration and checks for the current MessageType being assigned could be incorporated.

public void setType(byte bParamType)
```
    Set Message Type
    
    Parameters:
    
    bParamType - byte indicating Message Type
  - getBody
```
public byte[] getBody()
```
    Get Message body as array
    
    Returns:
    
    byte array message body
  - setBody
```
public void setBody(byte[] baParamBody)
```
    Set Message body, given a byte array input
    
    Parameters:
    
    baParamBody - message body byte array
  - setBody
```
public void setBody(byte[] baParamBody,
                    int iParamSize)
```
    Set Message body, given a byte array and a size parameter. This may be useful if user wants to initialize the message, and then continue to populate it later. This method is unused currently.
    
    Parameters:
    
    iParamSize - byte array size
    
    baParamBody - message body byte array
  - initBodySize
```
public void initBodySize(int iParamSize)
```
    Utility method to initialize Message body
    
    Parameters:
    
    iParamSize - byte array size
