public DefaultFilterChain(FilterChainFactory factory)

Method Detail

execute

public ProcessorResult execute(FilterChainContext ctx)

Execute this FilterChain.

Specified by:

execute in class AbstractFilterChain

Parameters:

ctx - FilterChainContext processing context

Returns:

ProcessorResult

Throws:

Exception

executeChain

protected boolean executeChain(FilterChainContext ctx,
                               DefaultFilterChain.FilterExecutor executor)
                        throws Exception

Sequentially lets each Filter in chain to process IOEvent.

Parameters:

ctx - FilterChainContext processing context

executor - DefaultFilterChain.FilterExecutor, which will call appropriate filter operation to process IOEvent.

Returns:

false to terminate exectution, or true for normal exection process

Throws:

Exception

postExecuteChain

protected boolean postExecuteChain(FilterChainContext ctx,
                                   DefaultFilterChain.FilterExecutor executor)
                            throws Exception

Sequentially lets each executed Filter to post process IOEvent. The Filters will be called in opposite order they were called on processing phase.

Parameters:

ctx - FilterChainContext processing context

executor - DefaultFilterChain.FilterExecutor, which will call appropriate filter operation to post process IOEvent.

Returns:

false to terminate exectution, or true for normal exection process

Throws:

Exception

throwChain

protected void throwChain(FilterChainContext ctx,
                          Throwable exception)

Notify the filters about error.

Parameters:

ctx - FilterChainContext

getCodec

public Codec getCodec()

Get filter chain codec

Returns:

filter chain codec
