All Known Implementing Classes:

DefaultHandlerContext
```
public interface HandlerContext
```
Enables a Handler to interact with its Pipeline and other handlers. Among other things a handler can notify the next Handler in the Pipeline as well as modify the Pipeline it belongs to dynamically.

- Method Detail
  - name
```
String name()
```
    Returns the name of the Handler.
    
    Returns:
    
    the name of the Handler
  - handler
```
Handler handler()
```
    Returns the associated Handler.
    
    Returns:
    
    the associated Handler
  - fireExceptionCaught
```
HandlerContext fireExceptionCaught(Exception cause)
```
    Received an Throwable in one of the inbound operations.
    This will result in having the Handler.exceptionCaught(HandlerContext, Exception) method called of the next Handler contained in the Pipeline.
    Note: It is guaranteed that this method will always be executed inside the dependentScheduler().
    
    Parameters:
    
    cause - the cause
  - fireRead
```
CompletableFuture<Void> fireRead(Address sender,
                                 Object msg,
                                 CompletableFuture<Void> future)
```
    Received a message.
    This will result in having the Handler.read(HandlerContext, Address, Object, CompletableFuture) method called of the next Handler contained in the Pipeline.
    Note: It is guaranteed that this method will always be executed inside the dependentScheduler().
    If an exception occurs during the execution of this method, the given msg is automatically released when it is of type ReferenceCounted.
    
    Parameters:
    
    sender - the sender of the message
    
    msg - the message
    
    future - the future of the message
  - fireEventTriggered
```
CompletableFuture<Void> fireEventTriggered(Event event,
                                           CompletableFuture<Void> future)
```
    Received an event.
    This will result in having the Handler.eventTriggered(HandlerContext, Event, CompletableFuture) method called of the next Handler contained in the Pipeline.
    Note: It is guaranteed that this method will always be executed inside the dependentScheduler().
    
    Parameters:
    
    event - the event
    
    future - the future of the message
  - write
```
CompletableFuture<Void> write(Address recipient,
                              Object msg,
                              CompletableFuture<Void> future)
```
    Request to write a message via this HandlerContext through the Pipeline.
    This will result in having the Handler.write(HandlerContext, Address, Object, CompletableFuture) method called of the next Handler contained in the Pipeline.
    Note: It is guaranteed that this method will always be executed inside the dependentScheduler().
    If an exception occurs during the execution of this method, the given msg is automatically released when it is of type ReferenceCounted.
    
    Parameters:
    
    recipient - the recipient of the message
    
    msg - the message
    
    future - the future of the message
  - config
```
DrasylConfig config()
```
    Returns the corresponding DrasylConfig.
    
    Returns:
    
    the corresponding DrasylConfig
  - pipeline
```
Pipeline pipeline()
```
    Returns the corresponding Pipeline.
    
    Returns:
    
    the corresponding Pipeline
  - independentScheduler
```
DrasylScheduler independentScheduler()
```
    Implementation Note: This method must always return a scheduler, that differs from the normal pipeline scheduler. E.g. the DrasylSchedulerUtil.getInstanceHeavy()
    This method returns an independent scheduler that does not add the given task to the same pool as the normal pipeline thread pool.
    
    Returns:
    
    independent scheduler DrasylScheduler
  - dependentScheduler
```
DrasylScheduler dependentScheduler()
```
    This method returns the same thread pool that is used by the normal pipeline processing. Tasks given to this scheduler should be short living.
    
    Returns:
    
    normal pipeline processing thread pool
  - identity
```
Identity identity()
```
    Returns the identity of this node.
    
    Returns:
    
    the identity of this node
  - peersManager
```
PeersManager peersManager()
```
    Returns the peers manager of this node.
    
    Returns:
    
    the peers manager of this node
  - inboundSerialization
```
Serialization inboundSerialization()
```
    Returns the inbound Serialization of this pipeline.
    
    Returns:
    
    the inbound Serialization
  - outboundSerialization
```
Serialization outboundSerialization()
```
    Returns the outbound Serialization of this pipeline.
    
    Returns:
    
    the outbound Serialization
