LogHandler

public LogHandler()

Method Detail

setConfig

public void setConfig(LogConfig config)

Sets the config object.

Specified by:

setConfig in interface ProtocolHandler

Parameters:

config - The singleton config object

setKey

public void setKey(SelectionKey key)

Sets the selection key for subsequent invocations.

Specified by:

setKey in interface ProtocolHandler

Parameters:

key - The nio selection key

doProcessRequest

public boolean doProcessRequest(ByteBuffer buffer,
                                int count)

Analyzes the buffer and return read active status.

Specified by:

doProcessRequest in interface ProtocolHandler

Parameters:

buffer - The buffer to look at

count - The number of new bytes in the buffer

Returns:

True if still active, false if done processing

doProcessResponse

public boolean doProcessResponse()
                          throws IOException

Creates and writes the response to the channel. Returns write active status. This method should return true if and only if the non-blocking channel cannot take all the response to be written.

Specified by:

doProcessResponse in interface ProtocolHandler

Returns:

True if still active, false if done processing

Throws:

IOException - Cannot write response to channel

doContinueResponse

public boolean doContinueResponse()
                           throws IOException

Continues writing the response to the channel. This method is only called if the initial write did not manage to write everything to the non-blocking channel.

Specified by:

doContinueResponse in interface ProtocolHandler

Returns:

True if still active, false if done processing

Throws:

IOException - Cannot write response to channel

requestPending

public boolean requestPending()

Tests the handler whether it needs to further process this request.

Specified by:

requestPending in interface ProtocolHandler

Returns:

True if the handler still needs to proceed, false if it is done
