Floating-point comparison with tolerance. More... | |
A boolean coordinate.
CoordinateExpr is intended to be used as a temporary in coordinate comparisons:
Point2D a(3.5,1.2); Point2D b(-1.5,4.3); std::cout << all(a.lt(b)) << std::endl; // false std::cout << any(a.lt(b)) << std::endl; // true
CoordinateExpr is not a true lazy-evaluation expression template, as that seems unnecessary when the object is typically only two bools large (smaller than the raw pointers necessary to implement a lazy solution). The consequence is that there's no short-circuiting of logical operators, but I don't think that will even remotely matter for most use cases. The any() and all() functions do support short-circuiting.

Return a fixed-size Eigen representation of the coordinate object.
The fact that this returns by const reference rather than by value should not be considered part of the API; this is merely an optimization enabled by the implementation.
