Classes

class  Gcs_log_event
 Entry or element in the circular buffer maintained by the Gcs_async_buffer responsible for storing a message that will eventually be asynchronously written to a sink. More...
 
class  Gcs_async_buffer
 Circular buffer that can be used to asynchronously feed a sink. More...
 
class  Gcs_output_sink
 Standard output sink. More...
 
class  Gcs_default_logger
 Default logger which is internally used by GCS and XCOM if nothing else is injected by Group Replication. More...
 
class  Gcs_default_debugger
 Default debugger which is used only by GCS and XCOM. More...
 
class  Gcs_debug_manager
 This class sets up and configures the debugging infrastructure, storing the debugger to be used by the application as a singleton. More...
 
class  Gcs_file_sink
