Request (OpenNMS 29.0.9 API)

All Superinterfaces:

Comparable<Delayed>, Delayed

All Known Implementing Classes:

JnaPingRequest, Jni6PingRequest, JniPingRequest
```
public interface Request<RequestIdT,RequestT extends Request<RequestIdT,RequestT,ResponseT>,ResponseT>
extends Delayed
```
A Request intended to be sent via a Messenger. This interfaces only provides for retrieving the id for the request so it can be matched against any replies. It also has methods that are using to indicate if an error has occurred or a timeout has occured.

Modifier and Type	Method	Description
`long`	`getDelay(TimeUnit unit)`	Indicates how many units of time are remaining until this request times out.
`RequestIdT`	`getId()`	Returns the id of this request.
`boolean`	`isProcessed()`	Returns true if this request has already been processed.
`void`	`processError(Throwable t)`	If an error or exception occurs during processing of this request then processError is called with the error or exception object.
`boolean`	`processResponse(ResponseT reply)`	Tell the request about a reply that come in with matched ids.

- Method Detail
  - getId
```
RequestIdT getId()
```
    Returns the id of this request. This is is matched against the id of a reply in order to associate replies with requests.
  - getDelay
```
long getDelay(TimeUnit unit)
```
    Indicates how many units of time are remaining until this request times out. Please note that this is the time REMAINING not the total timeout time. This method is inherited from Delayed
    
    Specified by:
    
    getDelay in interface Delayed
  - processResponse
```
boolean processResponse(ResponseT reply)
```
    Tell the request about a reply that come in with matched ids. Further processing is left to the request.
  - processTimeout
```
RequestT processTimeout()
```
    Notify this request that no reply has come in before its timeout has elapsed. (The timeout is indiciated using the getDelay method). If a retry should be attempted then a new request should be returned that can be retried, otherwise null should be returned.
  - processError
```
void processError(Throwable t)
```
    If an error or exception occurs during processing of this request then processError is called with the error or exception object.
  - isProcessed
```
boolean isProcessed()
```
    Returns true if this request has already been processed. This method should return true if and only if one of the process method has been called.
