ChannelProcessingFrame (EventMaid - Core Library 0.9.18 API)

java.lang.Object
- de.quantummaid.eventmaid.channel.ChannelProcessingFrame<T>

Type Parameters:

T - the type of messages of the Channel
```
public final class ChannelProcessingFrame<T>
extends Object
```
The ProcessingContext object stores the history of the traversed Channels in form of a linked list of ChannelProcessingFrames. For each Channel one ChannelProcessingFrame is added to the end of the list.
Each ProcessingContext stores the corresponding Channel, the Action that was executed as well as its preceding and succeeding frame. In case of the first frame in the list, the ChannelProcessingFrame.getPreviousFrame() returns null. Respective for the last frame the ChannelProcessingFrame#getNextFrame() ChannelStatistics.getNextFrame() returns null.
