Method Details
-
copy
Returns an exact copy of this JaxoLoop.- Parameters:
temp
- An instance of the loop to copy to (since this is an abstract class, we have to provide an instance of a sub-class).- Returns:
- A copy of this JaxoLoop.
-
isCopy
Determines if this JaxoObject is a copy of the specified one.- Overrides:
isCopy
in classJaxoParticleObject
- Parameters:
comp
- The JaxoObject to compare against.- Returns:
- True if the JaxoObjects are identical.
-
paint
The method that paints the JaxoObject.- Specified by:
paint
in classJaxoObject
- Parameters:
g2
- The graphics context where the object has to be painted.
-
getBounds
Returns the bounding box of this object.- Returns:
- the bounding box of this object.
-
latexCommand
The LaTeX command that is necessary to draw the given JaxoObject using the axodraw.sty package.- Specified by:
latexCommand
in classJaxoObject
- Parameters:
scale
- A scale factor to translate Java coordinates to LaTeX coordinates.canvasDim
- The current dimension of the canvas.- Returns:
- The corresponding axodraw LaTeX command.
-
paintVisualAid
Paints a visual aid for the user during dragging (moving or resizing) of this JaxoObject.- Overrides:
paintVisualAid
in classJaxoObject
- Parameters:
g2
- The graphics context to paint the visual aid.
-
arrowCoordinates
Returns the coordinates of the arrow of the current object.- Specified by:
arrowCoordinates
in classJaxoParticleObject
- Returns:
- The coordinates of the arrow of the current object.
-
rescaleObject
public final void rescaleObject(int orx, int ory, float scale) Rescale this JaxoObject by the scale factor scale, keeping the point (orx, ory) fixed.- Specified by:
rescaleObject
in classJaxoObject
- Parameters:
orx
- The x-coordinate of the fixed point.ory
- The y-coordinate of the fixed point.scale
- The scale parameter.
-
getLaTexCenter
Returns a center point which is used by the latexCommand method.- Parameters:
scaleFactor
- A scale factor.canvasHeight
- The height of the current canvas.- Returns:
- A Point2D object holding the center point.
-
getEquidistantPoints
Dividing the loop into n equidistant segments of length d, so n * d = 2 * r * PI is the circumference of the loop, this routine returns the n + 1 loop points that are i * d away from P1, where 0 invalid input: '<'= i invalid input: '<'= n.- Parameters:
n
- The number of segments to divide the loop.- Returns:
- The equidistant points of the loop.
-
getLaTexRadius
protected float getLaTexRadius(float scaleFactor) Returns a radius which is used by the latexCommand method.- Parameters:
scaleFactor
- A scale factor.- Returns:
- The latex radius.
-
getLaTexAngles
Returns an angle which is used by the latexCommand method. This is basically the relative angle between the center and the second (release) point of the loop.- Returns:
- A Point2D object with x-component the starting angle and y-component the starting angle + 360.
-
getObjectPath
Get the GeneralPath that paints this loop.- Returns:
- GeneralPath. May be null for an object that cannot be painted.
-
getAxo4JOptions
Return the option part of the LaTeX command for this line.- Parameters:
scale
- the axodraw4j scale factor.- Returns:
- the option String.
