| Ray (const Coordinate &a, const Coordinate &b) |
| Construct a ray, starting at a, and going through b.
|
|
| Ray (const LineData &d) |
| Construct a ray from a LineData.
|
|
Object * | transform (const Transformation &) const |
| Return this Object, transformed by the transformation t.
|
|
Ray * | copy () const |
| Returns a copy of this Object. More...
|
|
const ObjectType * | type () const |
| Returns the lowermost ObjectType that this object is an instantiation of. More...
|
|
bool | containsPoint (const Coordinate &p, const KigDocument &doc) const |
| Return whether this Curve contains the given point. More...
|
|
double | slope () const |
| Get the slope of this AbstractLine. More...
|
|
const TQString | equationString () const |
| Get a string containing the equation of this line in the form "y
= a * x + b ".
|
|
LineData | data () const |
| Get the LineData for this AbstractLine.
|
|
bool | equals (const Object &rhs) const |
| Returns true if this Object is equal to rhs. More...
|
|
Coordinate | attachPoint () const |
| Returns a reference point where to attach labels; when this returns an invalidCoord then the attachment is either not done at all, or done in a specific way (like for curves, or for points) The treatment of points could also take advantage of this attachment mechanism. More...
|
|
virtual Curve * | copy () const =0 |
| Returns a copy of this Object. More...
|
|
virtual bool | containsPoint (const Coordinate &p, const KigDocument &) const =0 |
| Return whether this Curve contains the given point. More...
|
|
bool | inherits (const ObjectType *t) const |
| Returns true if this Object inherits the Object type represented by t. More...
|
|
virtual Coordinate | attachPoint () const =0 |
| Returns a reference point where to attach labels; when this returns an invalidCoord then the attachment is either not done at all, or done in a specific way (like for curves, or for points) The treatment of points could also take advantage of this attachment mechanism. More...
|
|
virtual Object * | transform (const Transformation &t) const =0 |
| Return this Object, transformed by the transformation t.
|
|
bool | valid () const |
| Returns true if this is a valid Object. More...
|
|
virtual const ObjectType * | type () const =0 |
| Returns the lowermost ObjectType that this object is an instantiation of. More...
|
|
virtual Object * | copy () const =0 |
| Returns a copy of this Object. More...
|
|
virtual bool | equals (const Object &rhs) const =0 |
| Returns true if this Object is equal to rhs. More...

|
An Object representing a ray.
This means half of a line, it is infinite in one direction, but ends at a certain point in the other direction..
