java.lang.Object
- javax.faces.event.ExceptionQueuedEventContext

All Implemented Interfaces:

SystemEventListenerHolder
```
public class ExceptionQueuedEventContext
extends Object
implements SystemEventListenerHolder
```
This helper class provides context to the ExceptionQueuedEvent regarding the state of the system at the point in time when the ExceptionQueuedEvent occurs and links the ExceptionQueuedEvent to the ExceptionHandler by virtue of implementing SystemEventListener.

Since:

2.0

Field Summary

Fields
Modifier and Type	Field and Description
`static String`	`IN_AFTER_PHASE_KEY` The presence of an entry under this key in the `Map` returned from `getAttributes()` indicates the event occurred during the “after phase” part of the current lifecycle phase.
`static String`	`IN_BEFORE_PHASE_KEY` The presence of an entry under this key in the `Map` returned from `getAttributes()` indicates the event occurred during the “before phase” part of the current lifecycle phase.
