Member Function Documentation

◆ processEventImpl()

Logger::LoggerAppenderNull::processEventImpl ( int  type,
auto  params 
)
virtual

Processes the event to the physical target.

Must be implemented by non-abstract subclasses

serializeImpl()
Parameters
typesee "EVENT_xxx" constants
paramsprocessing parameters

Implements Logger::LoggerAppender.

◆ serializeImpl()

auto Logger::LoggerAppenderNull::serializeImpl ( LoggerEvent  event)
privatevirtual

Serializes the given event to put in the queue or write to the target device.

The appender implementaion can define any format for serialization. The data are passed to processEvent() method in the params argument when type is EVENT_LOG.

Returns
