Description copied from interface: CommunicationLog

Logs an HTTP message based on an OutputStream.

It does not block i.e. it can return before data is written to the output.

Specified by:

logMessage in interface CommunicationLog

Parameters:

direction - direction used for filename.

transportType - the transport protocol used i.e. udp, http, etc.

messageType - the type of the message i.e. request, response.

communicationContext - communication information such as target address and port

message - the output stream to branch to the log file.

Returns:

an output stream, that streams to the original output stream and optionally streams to another stream similarly to the tee Unix command. The other stream can be a log file stream.

logMessage

public OutputStream logMessage(CommunicationLog.Direction direction,
                               CommunicationLog.TransportType transportType,
                               CommunicationLog.MessageType messageType,
                               CommunicationContext communicationContext)

Description copied from interface: CommunicationLog

Creates an OutputStream to write the log message into.

Specified by:

logMessage in interface CommunicationLog

Parameters:

direction - direction used for filename.

transportType - the transport protocol used i.e. udp, http, etc.

messageType - the type of the message i.e. request, response.

communicationContext - communication information such as target address and port.

Returns:

an output stream to write the log message into.

logMessage

public InputStream logMessage(CommunicationLog.Direction direction,
                              CommunicationLog.TransportType transportType,
                              CommunicationLog.MessageType messageType,
                              CommunicationContext communicationContext,
                              InputStream message)

Description copied from interface: CommunicationLog

Logs an HTTP message based on an InputStream.

It blocks until everything has been read.

Specified by:

logMessage in interface CommunicationLog

Parameters:

direction - direction used for filename.

transportType - the transport protocol used i.e. udp, http, etc.

messageType - the type of the message i.e. request, response.

communicationContext - communication information such as target address and port

message - the message to log as input stream. As the input stream might be unusable after reading, another one is created to be used for further processing; see return value.

Returns:

a new input stream that mirrors the data from the message input data.
