PUFilter

public PUFilter()

Method Detail

register

public PUProtocol register(ProtocolFinder protocolFinder,
                           FilterChain filterChain)

Registers new ProtocolFinder - FilterChain pair, which defines the protocol.

Parameters:

protocolFinder - ProtocolFinder

filterChain - FilterChain

Returns:

PUProtocol, which wraps passed ProtocolFinder and FilterChain.

register

public void register(PUProtocol puProtocol)

Registers new PUProtocol.

Parameters:

puProtocol - PUProtocol

deregister

public void deregister(PUProtocol puProtocol)

Deregisters the PUProtocol.

Parameters:

puProtocol - PUProtocol

getProtocols

public java.util.Set<PUProtocol> getProtocols()

Get registered port unification protocols - PUProtocols.

Returns:

PUProtocol Set.

getBackChannelFilter

public Filter getBackChannelFilter()

Get the back channel Filter implementation, which should connect the custom protocol FilterChain with the main FilterChain. Usually developers shouldn't use this method, if they build custom protocol chains using getPUFilterChainBuilder(), otherwise they have to make sure there custom protocol FilterChain contains back channel Filter (usually first Filter in the custom protocol filter chain).

Returns:

back channel Filter.

getPUFilterChainBuilder

public FilterChainBuilder getPUFilterChainBuilder()

Returns the FilterChainBuilder, developers may use to build there custom protocol filter chain. The returned FilterChainBuilder may have some Filters pre-added.

Returns:

FilterChainBuilder.

                      throws java.io.IOException

Specified by:

handleEvent

public NextAction handleEvent(FilterChainContext ctx,
                              FilterChainEvent event)
                       throws java.io.IOException

Specified by:

handleEvent in interface Filter

Overrides:

handleEvent in class BaseFilter

Throws:
