writeTo

public void writeTo(JsonGenerator generator,
                    Event iLoggingEvent)
             throws IOException

Description copied from interface: JsonProvider

Writes information about the event, to the given generator.

When called, the generator is assumed to be within a JSON object context (i.e. this provider should write fields and their values to the generator). Upon return, the generator should be within the same JSON object context.

Parameters:

generator - the JsonGenerator to produce JSON content

iLoggingEvent - the event to convert into JSON

Throws:

IOException - if an I/O error occurs
