Constructor & Destructor Documentation

◆ RelativePoint() [1/5]

RelativePoint::RelativePoint ( )

Creates a point at the origin.

◆ RelativePoint() [2/5]

RelativePoint::RelativePoint ( Point< float > absolutePoint )

Creates an absolute point, relative to the origin.

◆ RelativePoint() [3/5]

RelativePoint::RelativePoint	(	float	absoluteX,
		float	absoluteY
	)

Creates an absolute point, relative to the origin.

◆ RelativePoint() [4/5]

RelativePoint::RelativePoint	(	const RelativeCoordinate &	x,
		const RelativeCoordinate &	y
	)

Creates an absolute point from two coordinates.

◆ RelativePoint() [5/5]

RelativePoint::RelativePoint ( const String & stringVersion )

Creates a point from a stringified representation.

The string must contain a pair of coordinates, separated by space or a comma. The syntax for the coordinate strings is explained in the RelativeCoordinate class.

Member Function Documentation

◆ operator==()

bool RelativePoint::operator== ( const RelativePoint & ) const

noexcept

◆ operator!=()

bool RelativePoint::operator!= ( const RelativePoint & ) const

noexcept

◆ resolve()

Point<float> RelativePoint::resolve ( const Expression::Scope * evaluationContext ) const

Calculates the absolute position of this point.

You'll need to provide a suitable Expression::Scope for looking up any coordinates that may be needed to calculate the result.

◆ moveToAbsolute()

void RelativePoint::moveToAbsolute	(	Point< float >	newPos,
		const Expression::Scope *	evaluationContext
	)

Changes the values of this point's coordinates to make it resolve to the specified position.

Calling this will leave any anchor points unchanged, but will set any absolute or relative positions to whatever values are necessary to make the resultant position match the position that is provided.

◆ toString()

String RelativePoint::toString ( ) const

Returns a string which represents this point.

This returns a comma-separated pair of coordinates. For details of the string syntax used by the coordinates, see the RelativeCoordinate constructor notes. The string that is returned can be passed to the RelativePoint constructor to recreate the point.
