NAME

6       Math::PlanePath::Base::NSEW -- multi-inheritance mixin for North,
7       South, East, West unit steps
8

SYNOPSIS

10        package Math::PlanePath::Foo;
11        use Math::PlanePath;
12        use Math::PlanePath::Base::NSEW;
13        @ISA = ('Math::PlanePath::Base::NSEW', 'Math::PlanePath');
14

DESCRIPTION

16       This is a multi-inheritance mixin for paths which take only steps
17       North, South, East and West by distance 1 each time.  This includes for
18       example the "SquareSpiral" and also things like the "DragonCurve" or
19       "CCurve".
20
21       The following path descriptive methods are provided
22
23                               value
24           dx_minimum()         -1
25           dx_maximum()          1
26           dy_minimum()         -1
27           dy_maximum()          1
28
29           dsumxy_minimum()     -1
30           dsumxy_maximum()      1
31           ddiffxy_minimum()    -1
32           ddiffxy_maximum()     1
33           dir_maximum_dxdy()   0,-1    # maximum South
