A location in the 2D plane freely positioned on a street.
This class restricts the Position class in the way that it must be a position on a street. As a consequence, this position can be described either by x and y coordinates or by a street and its distance to the beginning of the street (the relative position).
Should this class be derived from Position?

| AGPosition::AGPosition | ( | const AGStreet & | str, |
| SUMOReal | pos | ||
| ) | throw () |
Constructs an AGPosition at a certain point on a street.
An AGPosition is determined by a street and the relative position on the street. This relative position is the distance from the from node of the street.
param[in] str the street on which the AGPosition is located param[in] pos the distance from the from node of the street
Definition at line 43 of file AGPosition.cpp.
| AGPosition::AGPosition | ( | const AGStreet & | str | ) | throw () |
Constructs an AGPosition at a random point on a street.
This constructor determines the distance from the from node with a random number based on a uniform density.
param[in] str the street on which the AGPosition is located
Definition at line 48 of file AGPosition.cpp.
| Position AGPosition::compute2dPosition | ( | ) | const throw () [private] |
Creates a Position object to the street and position attribute of this class.
This method may only be called when street and position are initialised!
