Method Detail

handleRead

public NextAction handleRead(FilterChainContext ctx,
                             NextAction nextAction)
                      throws IOException

Description copied from class: FilterAdapter

Execute a unit of processing work to be performed, when channel will become available for reading. This Filter may either complete the required processing and return false, or delegate remaining processing to the next Filter in a FilterChain containing this Filter by returning true.

Specified by:

handleRead in interface Filter

Overrides:

handleRead in class FilterAdapter

Parameters:

ctx - FilterChainContext

nextAction - default NextAction, which Filter could change in order to control how FilterChain will continue the execution

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

IOException

handleWrite

public NextAction handleWrite(FilterChainContext ctx,
                              NextAction nextAction)
                       throws IOException

exceptionOccurred

public void exceptionOccurred(FilterChainContext ctx,
                              Throwable error)

Description copied from class: FilterAdapter

Notification about exception, occured on the FilterChain

Specified by:

exceptionOccurred in interface Filter

Overrides:

exceptionOccurred in class FilterAdapter

Parameters:

ctx - event processing FilterChainContext

error - error, which occurred during FilterChain execution
