Constructor Detail

LineSegment

public LineSegment(Vector startPoint,
                   Vector endPoint)

Creates a new line segment.

Parameters:

startPoint - the start point of a line segment.

endPoint - the end point of a line segment.

Method Detail

getStartPoint

public Vector getStartPoint()

Returns:

the start point

getEndPoint

public Vector getEndPoint()

Returns:

the end point

getLength

public float getLength()

Returns:

the length of this line segment

getBoundingRectangle

public Rectangle getBoundingRectangle()

Computes the bounding rectangle for this line segment. The rectangle has a rotation 0 degrees with respect to the coordinate system that the line system is in. For example, if a line segment is 5 unit long and sits at a 37 degree angle from horizontal, the bounding rectangle will have origin of the lower left hand end point of the segment, with width = 4 and height = 3.

Returns:

the bounding rectangle

transformBy

public LineSegment transformBy(Matrix m)

Transforms the segment by the specified matrix

Parameters:

m - the matrix for the transformation

Returns:

the transformed segment

containsSegment

public boolean containsSegment(LineSegment other)

Checks if a segment contains another segment in itself

Parameters:

other - a segment to be checked

Returns:

true if this segment contains other one, false otherwise

containsPoint

public boolean containsPoint(Vector point)

Checks if a segment contains a given point in itself

Parameters:

point - a point to be checked

Returns:

true if this segment contains given point, false otherwise
