- /* Tracing has evolved into two types, packet tracing and event tracing.
- Class Trace essentially supports packet tracing.
- However in addition to the basic tracing properties (that it derives from a BaseTrace class), pkt-tracing also requires to inherit some of the Connector class properties as well.
- Hence Trace should be renamed as ConnectorTrace in the future.
- And it shall have a BaseTrace * variable, where BaseTrace class supporting pure tracing functionalities and should be the parent class for all subsequent trace-related classes.
