A container for storing lists of points.
This class provides a convenient API for storing a list of points and performing some useful operations such as finding correspondences between two point lists. Additionally, though it is named PointList, it, in fact, behaves like a set, i.e., each point appears only once in the list. Thus, attempts to add duplicate points will be silently ignored.

| typedef List::const_reference lobot::PointList::const_reference |
These types are defined for STL compatibility and to allow this class to be used directly in STL algorithms.

| lobot::PointList::PointList | ( | int | n = 0 |
) |
Initalization: creates a point list with enough memory to initially store the specified number of points. If this memory fills up, not to worry, extra memory will be automagically acquired.

| void lobot::PointList::add | ( | int | x, | |
| int | y | |||
| ) |
This method adds a point to the point list. If the point already appears in the list, it will not be added a second time. Thus, this point list actually is a point set.

These functions allow clients to walk through the point list using STL algorithms.

| void lobot::PointList::clear | ( | ) | [inline] |
This function deletes all the entries in the point list.

This method checks if the point list has anything in it or not.
Definition at line 106 of file LoPointList.H.
For each point in this point list, find the closest point in the given point list P and return the resulting point list.
NOTE: If either this point list or the other point list is empty, this function will throw a lobot::misc_error with LOGIC_ERROR as the code.
