Member Function Documentation

Cubic* Cubic::copy

(

)

const [virtual]

Returns a copy of this Object.

The copy is an exact copy. Changes to the copy don't affect the original.

Implements Curve.

const ObjectType* Cubic::type

(

)

const [virtual]

Returns the lowermost ObjectType that this object is an instantiation of.

E.g. if you want to get a string containing the internal name of the type of an object, you can do:

 tn = object.type().internalName()

Implements Object.

bool Cubic::equals

(

const Object &

rhs

)

const [virtual]

Returns true if this Object is equal to rhs.

This function checks whether rhs is of the same Object type, and whether it contains the same data as this Object.

Implements Object.

bool Cubic::containsPoint	(	const Coordinate &	p,
		const KigDocument &
	)			const [virtual]

Return whether this Curve contains the given point.

This is implemented as a numerical approximation. lementations can/should use the value test_threshold in common.h as a threshold value.

Implements Curve.
