Processing IOEvent

processingHandler

protected IOEventProcessingHandler processingHandler

IOEventProcessingHandler is called to notify about IOEvent processing life-cycle events like suspend, resume, complete.

wasSuspended

Method Detail

create

public static Context create(Connection connection)

create

public static Context create(Connection connection,
                             Processor processor,
                             IOEvent ioEvent,
                             IOEventProcessingHandler processingHandler)

suspend

public void suspend()

Notify Context its processing will be suspended in the current thread.

resume

public void resume()

Notify Context its processing will be resumed in the current thread.

wasSuspended

public boolean wasSuspended()

Returns:

true if this IOEvent processing was suspended during its processing, or false otherwise.

setManualIOEventControl

public void setManualIOEventControl()

Switches processing to the manual IOEvent control. Connection.enableIOEvent(org.glassfish.grizzly.IOEvent) or Connection.disableIOEvent(org.glassfish.grizzly.IOEvent) might be explicitly called.

isManualIOEventControl

public boolean isManualIOEventControl()

Returns:

true, if processing was switched to the manual IOEvent control, or false otherwise.

getIoEvent

public IOEvent getIoEvent()

Get the processing IOEvent.

Returns:

the processing IOEvent.

setIoEvent

public void setIoEvent(IOEvent ioEvent)

Set the processing IOEvent.

Parameters:

ioEvent - the processing IOEvent.

getConnection

public Connection getConnection()

Get the processing Connection.

Returns:

the processing Connection.

setConnection

public void setConnection(Connection connection)

Set the processing Connection.

Parameters:

connection - the processing Connection.

getProcessor

public Processor getProcessor()

Get the Processor, which is responsible to process the IOEvent.

Returns:

the Processor, which is responsible to process the IOEvent.

setProcessor

public void setProcessor(Processor processor)

Set the Processor, which is responsible to process the IOEvent.

Parameters:

processor - the Processor, which is responsible to process the IOEvent.

getProcessingHandler

public IOEventProcessingHandler getProcessingHandler()

setProcessingHandler

public void setProcessingHandler(IOEventProcessingHandler processingHandler)

getAttributes

public AttributeHolder getAttributes()

Get attributes (AttributeHolder), associated with the processing Context. AttributeHolder is cleared after each I/O event processing. Method may return null, if there were no attributes added before.

Specified by:

getAttributes in interface AttributeStorage

Returns:

attributes (AttributeHolder), associated with the processing Context.

reset

public void reset()

If implementation uses ObjectPool to store and reuse Context instances - this method will be called before Context will be offered to pool.

recycle

public void recycle()

Recycle this Context

Specified by:

recycle in interface Cacheable
