If op is the operator you are responsible for, and if the argument internal::DataSource is of the correct type, then return an appropriate DataSource. 
UnaryOperator contains information on some unary operator that operates on one arg of a certain type.
Examples of unary operators are logical not for booleans, unary minus for ints, unary minus for doubles, unary minus for vectors, unary plus for ints (internal::identity operator) etc. We always provide templates that accept a STL style adaptable functor..

virtual base::DataSourceBase* RTT::types::UnaryOp::build  (  const std::string &  op, 
base::DataSourceBase *  a  
)  [pure virtual] 
If op is the operator you are responsible for, and if the argument internal::DataSource is of the correct type, then return an appropriate DataSource.
( i.e. a internal::DataSource that will apply a certain operation on the value it gets from its argument internal::DataSource, and will return that value ). Otherwise, return 0.
Implemented in RTT::types::UnaryOperator< function >.
