create()

std::unique_ptr< Variable > Variable::create ( const std::string &  name, const std::string &  type = "float", int  index = -1  )

staticinherited

create and return a new Variable of a given name & type.

If type is a vector an index can be specified : the variable will behave as a non-vector Variable corresponding to the value at the given index
