Method Detail

getRotationAngle

public final int getRotationAngle()

Returns the rotation angle of this vertex.

Specified by:

getRotationAngle in interface JaxoRotationObject

Returns:

The rotation angle of this vertex (in degrees).

setRotationAngle

public final void setRotationAngle(int angle)

Sets the rotation angle of this vertex, this only acts on P2.

Specified by:

setRotationAngle in interface JaxoRotationObject

Parameters:

angle - The rotation angle of this vertex (in degrees).

copy

public final JaxoObject copy(JaxoVertex temp)

Returns an exact copy of this JaxoVertex.

Parameters:

temp - An instance of the vertex to copy to.

Returns:

A copy of this JaxoVertex.

isCopy

public boolean isCopy(JaxoObject comp)

Determines if this JaxoObject is a copy of the specified one.

Overrides:

isCopy in class JaxoExtendedObject

Parameters:

comp - The JaxoObject to compare against.

Returns:

True if the JaxoObjects are identical.

paintVisualAid

public final void paintVisualAid(JaxoGraphics2D g2)

Paints a visual aid for the user during dragging (moving or resizing) of this JaxoObject.

Overrides:

paintVisualAid in class JaxoObject

Parameters:

g2 - The graphics context to paint the visual aid.

rescaleObject

public final void rescaleObject(int orx,
                                int ory,
                                float scale)

Specified by:

rescaleObject in class JaxoObject

Parameters:

orx - The x-coordinate of the fixed point.

ory - The y-coordinate of the fixed point.

scale - The scale parameter.
