Detailed Description

Line class.

An instance of Line represents an instance of the geometric representation "line". A line has the following properties.

• color - the color of the line
• vertex1 - the first vertex of the line
• vertex2 - the second vertex of the line

  The class Line is derived from the classes GeometricObject and Vertex2. See these classes for further information concerning interface and additional methods.

Constructor & Destructor Documentation

BALL::VIEW::Line::Line

(

)

Default Constructor.

Construct new line. The properties of this line are set to:

• color - to the color black
• vertex1 - to the vector (0,0,0)
• vertex2 - to the vector (0,0,0)

  Returns:

  Line new constructed line

Member Function Documentation

virtual void BALL::VIEW::Line::clear

(

)

[virtual]

Explicit default initialization.

Calls GeometricObject::clear. Calls Vertex2::clear.

See also:

GeometricObject::clear

Vertex2::clear

Reimplemented from BALL::VIEW::Vertex2.

virtual void BALL::VIEW::Line::dump	(	std::ostream &	s = std::cout,
		Size	depth = 0
	)			const [virtual]

Internal value dump.

Dump the current value of this line to the output ostream s with dumping depth depth. Calls GeometricObject::dump. Calls Vertex2::dump.

Parameters:

	s	output stream where to output the value of this line
	depth	the dumping depth

See also:

GeometricObject::dump

Vertex2::dump

Reimplemented from BALL::VIEW::Vertex2.

virtual bool BALL::VIEW::Line::isValid

(

)

const [virtual]

Internal state and consistency self-validation.

Initiate self-validation of the internal state and data structure consistencies of this line. If the internal state of this line is correct (self-validated) and consistent true is returned, false otherwise. Calls GeometricObject::isValid. Calls Vertex2::isValid.

Returns:

bool true if the internal state of this line is correct (self-validated) and consistent, false otherwise

See also:

GeometricObject::isValid

Vertex2::isValid

Reimplemented from BALL::VIEW::Vertex2.

const Line& BALL::VIEW::Line::operator=

(

const Line &

line

)

Assignment operator.

Calls set.

void BALL::VIEW::Line::set

(

const Line &

line

)

Assign the line line to this line.

the line line.

void BALL::VIEW::Line::swap

(

Line &

line

)

Swapping of line's.

Swap the value of this line with the line line.

Parameters:

line

the line being swapped with this line
