2.4.2 FileConsumer

class eprosima::fastdds::dds::FileConsumer : public eprosima::fastdds::dds::OStreamConsumerFileConsumer()
Default constructor: filename = “output.log”, append = false.FileConsumer(const std::string &filename, bool append = false)
Constructor with parameters.Parameters:
* filename – path of the output file where the log will be wrote.
* append – indicates if the consumer must append the content in the filename.

2.4.3 Log

class eprosima::fastdds::dds::Log

Logging utilities. Logging is accessed through the three macros above, and configuration on the log output can be achieved through static methods on the class. Logging at various levels can be disabled dynamically (through the Verbosity level) or statically (through the LOG_NO_[VERB] macros) for maximum performance.

2.4.4 LogConsumer

class LogConsumer
Consumes a log entry to output it somewhere.Subclassed by eprosima::fastdds::dds::OStreamConsumer
