Method Detail

handleRead

public NextAction handleRead(FilterChainContext ctx)
                      throws IOException

Description copied from class: BaseFilter

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 BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

IOException

handleWrite

public NextAction handleWrite(FilterChainContext ctx)
                       throws IOException

Description copied from class: BaseFilter

Execute a unit of processing work to be performed, when some data should be written on channel. 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:

handleWrite in interface Filter

Overrides:

handleWrite in class BaseFilter

Parameters:

ctx - FilterChainContext

Returns:

NextAction instruction for FilterChain, how it should continue the execution

Throws:

IOException

decode

public MultiStringFilter.DecodeResult decode(Buffer inputBuffer,
                                             MultiStringFilter.DecodeResult decodeResult)

encode

public Buffer encode(MemoryManager mm,
                     List<String> inputStringList)
              throws IOException

Throws:

IOException

parseWithLengthPrefix

protected MultiStringFilter.DecodeResult parseWithLengthPrefix(Buffer input,
                                                               MultiStringFilter.DecodeResult decodeResult)

parseWithTerminatingSeq

protected MultiStringFilter.DecodeResult parseWithTerminatingSeq(Buffer input,
                                                                 MultiStringFilter.DecodeResult decodeResult)
