| Line | | public Line(Report report, Section section, double thickness, Color color, boolean visible)(Code) | | Constructor.
Parameters:
report - the report containing this line
Parameters:
section - the section containing this line
Parameters:
thickness - the line thickness
Parameters:
color - may be null
Parameters:

| Line | | public Line(Report report, Section section, double thickness, Color color, boolean visible, Point p0, Point p1)(Code) | | Constructor.
Parameters:
report - the report containing this line
Parameters:
section - the section containing this line
Parameters:
thickness - the line thickness
Parameters:
color - may be null
Parameters:
visible - show/hide flag
Parameters:
p0 - one end point of the line
Parameters:
p1 - the other end point of the line |
| addEndPoint | | public void addEndPoint(double x, double y)(Code) | | Adds an end point to the line. Used when constructing a line from XML,
where we don't see the point until after creating this line.
Parameters:
x - the x coordinate
Parameters:
y - the y coordinate |
| getColor | | public Color getColor()(Code) | | Returns the line's color. The return value will never be
null.
the line's color |
| getPoint | | public Point getPoint(int index)(Code) | | Returns one of the two end points of the line.
Parameters:
index - either 0 or 1 a point |
| getThickness | | public double getThickness()(Code) | | Returns the line thickness.
the line thickness |
| length | | public double length()(Code) | | Returns the length of the line.
the distance between the two end points |
| setColor | | public void setColor(Color c)(Code) | | Sets the line's color. If c is null, then the
color is set to DEFAULT_COLOR.
Parameters:
c - new line color; if null, color is set toDEFAULT_COLOR |
| setPoint | | public void setPoint(Point newPoint, int index)(Code) | | Sets one of the two end points.
Parameters:
newPoint - a point
Parameters:
index - either 0 or 1 |
| setThickness | | public void setThickness(double newThickness)(Code) | | Sets the line thickness.
Parameters:
newThickness - the new line thickness |
| toString | | public String toString()(Code) | | Returns a string representation of this line.
a string representing this line |
| writeXML | | public void writeXML(XMLWriter out)(Code) | | Writes this line as an XML tag.
Parameters:
out - a writer that knows how to write XML |
