Constructor Detail

SSLFilter

public SSLFilter()

SSLFilter

public SSLFilter(SSLEngineConfigurator sslEngineConfigurator)

Build SSLFilter with the given SSLEngineConfigurator.

Parameters:

sslEngineConfigurator - SSLEngine configurator

SSLFilter

public SSLFilter(SSLEngineConfigurator sslEngineConfigurator,
                 SSLHandshaker sslHandshaker)

Build SSLFilter with the given SSLEngineConfigurator and custom SSLHandshaker

Parameters:

sslEngineConfigurator - SSLEngine configurator

Method Detail

handleRead

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

Wraps FilterChainContext default StreamReader and StreamWriter with SSL aware ones.

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

postRead

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

Execute any cleanup activities, such as releasing resources that were acquired during the execution of Filter#handleRead(com.sun.grizzly.FilterChainContext) method of this Filter instance.

Specified by:

postRead in interface Filter

Overrides:

postRead 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

Execute a unit of processing work to be performed, when channel will become available for writing. 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 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

postWrite

public NextAction postWrite(FilterChainContext ctx,
                            NextAction nextAction)
