Method Details

writeTo

void writeTo(JsonGenerator generator,
 Event event)
      throws IOException

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

event - the event to convert into JSON

Throws:

IOException - if an I/O error occurs

prepareForDeferredProcessing

void prepareForDeferredProcessing(Event event)

Gives the provider a chance to perform more deferred processing (in addition to what is already provided by DeferredProcessingAware.prepareForDeferredProcessing()).

Parameters:

event - the event to prepare for deferred processing

start

void start()

Start the provider after all configuration properties are set.

stop

void stop()

Stop the provider

isStarted

boolean isStarted()

Report whether the provider is started or not.

Returns:

true if the provider is started, false otherwise.
