## Detailed Description

### template<class TRADER_LOCK_TYPE, class MAP_LOCK_TYPE>
class TAO_Trader< TRADER_LOCK_TYPE, MAP_LOCK_TYPE >

This class packages together all the various pieces that provide functionality specified in COS Trading specification.

TAO_Trader contains all the components that together represent a single trader. Based on its constructor arguments, TAO_Trader creates instances of appropriate interface implementations as well as instances of objects common to more than one interface (offers, attributes, etc.). TAO_Trader also enforces the proper order on all initializations. TAO_Trader acts like a "glue" class that creates appropriate components, holds everything together, and enforces order. TAO_Trader is parameterized by two types of locks: one for its service service offers, one for its state (configuration).
