Detailed Description

Message handler that prints all received messages as JSON to a Print stream.

This class implements the MessageHandler interface and outputs the content of all received messages (float, Coordinate<float>, GPSCoordinate) in JSON format to the provided Print object (e.g., Serial, file, etc). It uses the shared string arrays to print the message type, unit, and source as readable text.

Example usage:

MessageHandlerPrintJSON printer(Serial);
source.subscribe(printer);

This is useful for logging, exporting, or integrating message traffic with systems that consume JSON data.

Member Function Documentation

onMessage() [1/4]

bool onMessage ( const Message< Coordinate< float > > &  msg )

inlineoverridevirtual

Reimplemented from MessageHandler.

onMessage() [2/4]

bool onMessage ( const Message< float > &  msg )

inlineoverridevirtual

Handle an incoming message (pure virtual).

This method should be implemented by derived classes to process messages.

Parameters

msg	The message to handle.

Returns

true if the message was handled successfully, false otherwise.

Implements MessageHandler.

onMessage() [3/4]

bool onMessage ( const Message< GPSCoordinate > &  msg )

inlineoverridevirtual

Reimplemented from MessageHandler.

onMessage() [4/4]

bool onMessage ( const Message< MotionState3D > &  msg )

inlineoverridevirtual

Reimplemented from MessageHandler.
