Member Function Documentation

BaseType * rvalue::bvalue ( const string &  dataset,
DDS dds 
)

Return the BaseType * for a given rvalue. If the rvalue is a func_rvalue, evaluates the func_rvalue and returns the result. The functions referenced by func_rvalues must encapsulate their return values in BaseType *s.

Parameters:
dataset The dataset name to pass to a function (which may call BaseType::read() using that arguemnt).
dds The dds to pass to a function.
