Member Function Documentation

Center()

Point2D< double > Center ( ) const

inlinenoexcept

Gets the center of the circle.

Returns

The center.

Exceptions

Does	not throw any exception.

Contains()

bool Contains ( Point2D< double >  point ) const

inlinenoexcept

Check whether a point is inside or outside a circle.

Parameters

[in]

point

Point to be checked.

Returns

bool True if the point is inside the circle, false otherwise.

Exceptions

Does	not throw any exception.

IsOnRadius()

bool IsOnRadius ( Point2D< double >  point, double  epsilon  ) const

inlinenoexcept

Check whether a point is on the radius of a circle.

Parameters

[in]	point	Point to be checked.
[in]	epsilon	Maximum allowable deviation.

Returns

True if the point lies within the allowable deviation of the circle's radius, false otherwise.

Exceptions

Does	not throw any exception.

operator!=()

bool operator!= ( const Circle &  circle ) const

inlinenoexcept

Compares to an other circle.

Parameters

[in]

circle

Other circle.

Returns

True if not equal, otherwise false.

Exceptions

Does	not throw any exception.

operator==()

bool operator== ( const Circle &  circle ) const

inlinenoexcept

Compares to an other circle.

Parameters

[in]

circle

Other circle.

Returns

True if equal, otherwise false.

Exceptions

Does	not throw any exception.

Radius()

double Radius ( ) const

inlinenoexcept

Gets the radius of the circle.

Returns

The radius.

Exceptions

Does	not throw any exception.

SetCenter()

void SetCenter ( Point2D< double >  center )

inlinenoexcept

Sets the center of the circle.

Parameters

[in]

center

The new center.

Exceptions

Does	not throw any exception.

SetRadius()

void SetRadius ( double  radius )

inlinenoexcept

Sets the radius of the circle.

Parameters

[in]

radius

If the radius is negative, the absolute value is used.

Exceptions
