Member Function Documentation

IlvPos IlvPoint::getX

(

)

const

Retrieves the current x coordinate.

Returns:

The current x coordinate of this object.

IlvPos IlvPoint::getY

(

)

const

Retrieves the current y coordinate.

Returns:

The current y coordinate of this object.

void IlvPoint::move	(	IlvPos	x,
		IlvPos	y
	)

Sets the new position.

Parameters:

	x	The new x coordinate of this object.
	y	The new y coordinate of this object.

int IlvPoint::operator!=

(

const IlvPoint &

p

)

const

Inequality operator.

Parameters:

p

The point to compare to.

Returns:

1 if p is different than the current object.

IlvPoint& IlvPoint::operator=

(

const IlvPoint &

p

)

Assignment operator.

Parameters:

p

The point that is copied to the current object.

int IlvPoint::operator==

(

const IlvPoint &

p

)

const

Equality operator.

Parameters:

p

The point to compare to.

Returns:

0 if p is different than the current object.

void IlvPoint::set	(	IlvPos	x,
		IlvPos	y
	)

Sets the new position.

Parameters:

	x	The new x coordinate of this object.
	y	The new y coordinate of this object.

void IlvPoint::setX

(

IlvPos

newX

)

Sets the x coordinate.

Parameters:

newX

The new x coordinate of this object.

void IlvPoint::setY

(

IlvPos

yy

)

Sets the y coordinate.

Parameters:

newY

The new y coordinate of this object.

void IlvPoint::translate

(

const IlvPoint &

delta

)

Translates to a new position.

Shifts an existing point to another location by means of a vector. You indicate the x and y translation values that represent the distance between the current position of the point and the target future position.

Parameters:

delta

The translation vector that is applied.

void IlvPoint::translate	(	IlvPos	dx,
		IlvPos	dy
	)

Translates to a new position.

Shifts an existing point to another location by means of a vector. You indicate the x and y translation values that represent the distance between the current position of the point and the target future position.

Parameters:

	dx	The x translation to be applied to the object.
	dy	The y translation to be applied to the object.

void IlvPoint::x

(

IlvPos

newX

)

Sets the x coordinate.

Parameters:

newX

The new x coordinate of this object.

IlvPos IlvPoint::x

(

)

const

Retrieves the current x coordinate.

Returns:

The current x coordinate of this object.

void IlvPoint::y

(

IlvPos

newY

)

Sets the y coordinate.

Parameters:

newY

The new y coordinate of this object.

IlvPos IlvPoint::y

(

)

const

Retrieves the current y coordinate.

Returns:

The current y coordinate of this object.
