Ex. 8.6: containsPoint one-line solution

[Jemcik]

Code: (Objective-C)

-(BOOL) containsPoint: (XYPoint *) aPoint
{
    return (aPoint.x >= origin.x && aPoint.x <= (origin.x + width) && aPoint.y >= origin.y && aPoint.y <= (origin.y + height) ? TRUE : FALSE);
}

Of course, if you want to check it, you will need to do something like this in main.m:

Code: (Objective-C)

#import <Foundation/Foundation.h>
#import "Rectangle.h"

int main (int argc, const char * argv[])
{
    @autoreleasepool
    {
        Rectangle *rect = [Rectangle new];
        [rect setWidth:30 setHeight:20];
        [rect setOriginX:10 setOriginY:15];

        XYPoint *point = [XYPoint new];
        [point setX:15 setY:20];
        
        if ([rect containsPoint:point])
            printf("Rectangle encloses this point.");
        else
            printf("Rectangle does not enclose this point.");
    }
    return 0;
}
