public class EpollHandler
extends Object
implements IoHandler
```
IoHandler which uses epoll under the covers. Only works on Linux!

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`deregister(IoHandle handle)`	Deregister a `IoHandle` for IO.
`void`	`destroy()`	Destroy the `IoHandler` and free all its resources.
`boolean`	`isCompatible(Class<? extends IoHandle> handleType)`	Returns `true` if the given type is compatible with this `IoHandler` and so can be registered, `false` otherwise.
`static IoHandlerFactory`	`newFactory()`	Returns a new `IoHandlerFactory` that creates `EpollHandler` instances.
`static IoHandlerFactory`	`newFactory(int maxEvents, SelectStrategyFactory selectStrategyFactory)`	Returns a new `IoHandlerFactory` that creates `EpollHandler` instances.
`void`	`prepareToDestroy()`	Prepare to destroy this `IoHandler`.
`void`	`register(IoHandle handle)`	Register a `Channel` for IO.
`int`	`run(IoExecutionContext context)`	Run the IO handled by this `IoHandler`.
`void`	`wakeup(boolean inEventLoop)`	Wakeup the `IoHandler`, which means if any operation blocks it should be unblocked and return as soon as possible.

  - newFactory
```
public static IoHandlerFactory newFactory()
```
    Returns a new IoHandlerFactory that creates EpollHandler instances.
  - newFactory
```
public static IoHandlerFactory newFactory(int maxEvents,
                                          SelectStrategyFactory selectStrategyFactory)
```
    Returns a new IoHandlerFactory that creates EpollHandler instances.
  - register
```
public final void register(IoHandle handle)
                    throws Exception
```
    Description copied from interface: IoHandler
    
    Register a Channel for IO.
    
    Specified by:
    
    register in interface IoHandler
    
    Parameters:
    
    handle - the Channel to register..
    
    Throws:
    
    Exception - thrown if an error happens during registration.
  - deregister
```
public final void deregister(IoHandle handle)
                      throws Exception
```
    Description copied from interface: IoHandler
    
    Deregister a IoHandle for IO.
    
    Specified by:
    
    deregister in interface IoHandler
    
    Parameters:
    
    handle - the IoHandle to deregister..
    
    Throws:
    
    Exception - thrown if an error happens during deregistration.
  - wakeup
```
public final void wakeup(boolean inEventLoop)
```
    Description copied from interface: IoHandler
    
    Wakeup the IoHandler, which means if any operation blocks it should be unblocked and return as soon as possible.
    
    Specified by:
    
    wakeup in interface IoHandler
  - run
```
public final int run(IoExecutionContext context)
```
    Description copied from interface: IoHandler
    
    Run the IO handled by this IoHandler. The IoExecutionContext should be used to ensure we not execute too long and so block the processing of other task that are scheduled on the EventLoop. This is done by taking IoExecutionContext.delayNanos(long) or IoExecutionContext.deadlineNanos() into account.
    
    Specified by:
    
    run in interface IoHandler
    
    Returns:
    
    the number of IoHandle for which I/O was handled.
  - prepareToDestroy
```
public void prepareToDestroy()
```
    Description copied from interface: IoHandler
    
    Prepare to destroy this IoHandler. This method will be called before IoHandler.destroy() and may be called multiple times.
    
    Specified by:
    
    prepareToDestroy in interface IoHandler
  - destroy
```
public final void destroy()
```
    Description copied from interface: IoHandler
    
    Destroy the IoHandler and free all its resources.
    
    Specified by:
    
    destroy in interface IoHandler
  - isCompatible
```
public boolean isCompatible(Class<? extends IoHandle> handleType)
```
    Description copied from interface: IoHandler
    
    Returns true if the given type is compatible with this IoHandler and so can be registered, false otherwise.
    
    Specified by:
    
    isCompatible in interface IoHandler
    
    Parameters:
    
    handleType - the type of the IoHandle.
    
    Returns:
    
    if compatible of not.
