view accumulator.h @ 421:166312a124bc api-inversion

Code spaghettification continues.

Include accumulator.h in audioDB.h.  This means we also need
audioDB_API.h in there, to get the definition of adb_result_t.  Use
preprocessor defines to prevent audioDB_API.h from being included
multiple times.

Include an accumulator field in class audioDB.

class Accumulator {
public:
  virtual ~Accumulator() {};
  virtual void add_point(adb_result_t *r) = 0;
  virtual adb_query_results_t *get_points() = 0;
};
