MessageInfo (Java EE 8)

```
public interface MessageInfo
```
A message processing runtime uses this interface to pass messages and message processing state to authentication contexts for processing by authentication modules.
This interface encapsulates a request message object and a response message object for a message exchange. This interface may also be used to associate additional context in the form of key/value pairs, with the encapsulated messages.
Every implementation of this interface should provide a zero argument constructor, and a constructor which takes a single Map argument. Additional constructors may also be provided.

- Method Detail
  - getRequestMessage
```
java.lang.Object getRequestMessage()
```
    Get the request message object from this MessageInfo.
    
    Returns:
    
    An object representing the request message, or null if no request message is set within the MessageInfo.
  - getResponseMessage
```
java.lang.Object getResponseMessage()
```
    Get the response message object from this MessageInfo.
    
    Returns:
    
    an object representing the response message, or null if no response message is set within the MessageInfo.
  - setRequestMessage
```
void setRequestMessage(java.lang.Object request)
```
    Set the request message object in this MessageInfo.
    
    Parameters:
    
    request - An object representing the request message.
  - setResponseMessage
```
void setResponseMessage(java.lang.Object response)
```
    Set the response message object in this MessageInfo.
    
    Parameters:
    
    response - An object representing the response message.
  - getMap
```
java.util.Map getMap()
```
    Get (a reference to) the Map object of this MessageInfo. Operations performed on the acquired Map must effect the Map within the MessageInfo.
    
    Returns:
    
    the Map object of this MessageInfo. This method never returns null. If a Map has not been associated with the MessageInfo, this method instantiates a Map, associates it with this MessageInfo, and then returns it.
