Class PUReadFilter

java.lang.Object
  com.sun.grizzly.filter.ReadFilter
      com.sun.grizzly.portunif.PUReadFilter

All Implemented Interfaces:

ProtocolFilter, ReinvokeAware

public class PUReadFilter
extends ReadFilter

Port unification ReadFilter. Could be used for usecases, where on one TCP/UDP/... port several higher level protocols should be served (for example HTTP, HTTPS, IIOP). If input ByteBuffer is empty - ReadFilter logic will be executed in order to read request data.

configure

public void configure(Properties props)

Configures port unification depending on passed Properties

Parameters:

props - Properties

configure

public void configure(List<ProtocolFinder> protocolFinders,
                      List<ProtocolHandler> protocolHandlers,
                      List<PUPreProcessor> preProcessors)

Configures port unification depending on passed Lists

Parameters:

protocolFinders - ProtocolFinders

protocolHandlers - ProtocolHandlers

preProcessors - PUPreProcessors

addProtocolFinder

public void addProtocolFinder(ProtocolFinder protocolFinder)

Add an instance of ProtocolFinder

removeProtocolFinder

public void removeProtocolFinder(ProtocolFinder protocolFinder)

Remove a ProtocolFinder

addProtocolHandler

public void addProtocolHandler(ProtocolHandler protocolHandler)

Add an instance of ProtocolHandler

removeProtocolHandler

public void removeProtocolHandler(ProtocolHandler protocolHandler)

Remove a ProtocolHandler

addPreProcessor

public void addPreProcessor(PUPreProcessor preProcessor)

Add PUPreProcessor to preprocess income request

removePreProcessor

public void removePreProcessor(PUPreProcessor preProcessor)

Remove PUPreProcessor from preprocess queue

setReadTimeout

public void setReadTimeout(long readTimeout)

Set readTimeout. Time interval PUReadFilter will expect more data on channel. If no ProtocolFinder found - Filter tries to read more data and rerun finders.

Parameters:

readTimeout - new timeout value

getReadTimeout

public long getReadTimeout()

Get readTimeout. Time interval PUReadFilter will expect more data on channel. If no ProtocolFinder found - Filter tries to read more data and rerun finders.

Returns:

read timeout value
