Method Detail

writeTo

public void writeTo(JsonGenerator generator,
                    ILoggingEvent event)
             throws IOException

Description copied from interface: JsonProvider

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

event - the event to convert into JSON

Throws:

IOException - if an I/O error occurs

getThrowable

protected abstract IThrowableProxy getThrowable(ILoggingEvent event)

Parameters:

event - the event being logged, never null

Returns:

the throwable to use, or null if no appropriate throwable is available

Throws:

NullPointerException - if event is null
