Member Function Documentation

virtual vector<Point*> Region::discrete

(

double

resolution

)

[pure virtual]

Turn the defined region into a discrete set of points, using resolution to describe the level of detail.

Parameters:

resolution

Level of spacing (detail) between the discrete points to be created. Value in kilometers.

Returns:

List of points that describe this region using the level of resolution requested

Implemented in RegionArea, and RegionLine.

virtual bool Region::contains

(

Point *

p

)

[pure virtual]

Check if this region contains the given point.

Parameters:

p

Point to check against

Returns:

True if point is inside this region, false otherwise

Implemented in RegionArea, and RegionLine.

virtual void Region::add

(

Point *

p

)

[pure virtual]

Add the given Point to this Region, expanding the region as needed so that contains(p) returns true.

Parameters:

p

The point to include in this region

Implemented in RegionArea, and RegionLine.
