Detailed Description
The most generic interface to a position/turn counter, for encoding positions.
Within one turn, there are resolution() position increments. After a turn-increment, the position will be exactly zero or resolution(). An upcounting() == true encoder will count from zero to resolution() between two turn increments. An upcounting() == false encoder will count from resolution() to zero between two turn increments.

Constructor & Destructor Documentation
| RTT::EncoderInterface::EncoderInterface | ( | const std::string & | name | ) | [inline] |
Create a EncoderInterface with a name.
When name is not "", and unique, it can be retrieved through EncoderInterface::nameserver .
Definition at line 74 of file EncoderInterface.hpp.
Member Function Documentation
| virtual int RTT::EncoderInterface::resolution | ( | ) | const [pure virtual] |
Return the position resolution.
This number can be negative or positive and denotes the the maximal or minimal value positionGet().
| virtual bool RTT::EncoderInterface::upcounting | ( | ) | const [pure virtual] |
Returns true if after a positive turn increment, position increments positively.
Meaning from 0 to |resolution()| or from resolution() to zero if resolution() < 0
