Constructor Detail

XArrowTip

public XArrowTip()

Constructor. Angle: 0.4, radius: 8

XArrowTip

public XArrowTip(double angle,
                 double outerRadius,
                 double innerRadius)

Value constructor.

Parameters:

angle - Pointiness of arrow

outerRadius - Outer radius

innerRadius - Inner radius

Method Detail

outline

public java.awt.Polygon outline(int x1,
                                int y1,
                                int x2,
                                int y2)

Calculates the outline of an arrow tip.

Specified by:

outline in class CH.ifa.draw.figures.AbstractLineDecoration

Parameters:

x1 - Arrow tip

y1 - Arrow tip

x2 - Arrow base

y2 - Arrow base

Returns:

The polygon describing the outline

getAngle

public double getAngle()

Gets the pointiness of arrow. A smaller angle leads to a pointier arrow. The angle is measured between the arrow line and one of the points at the side of the arrow. Thus, the total angle at the arrow tip is the double of the angle specified.

setAngle

public void setAngle(double angle)

Sets the pointiness of arrow. A smaller angle leads to a pointier arrow. The angle is measured between the arrow line and one of the points at the side of the arrow. Thus, the total angle at the arrow tip is the double of the angle specified.

getOuterRadius

public double getOuterRadius()

Gets the outer radius.

setOuterRadius

public void setOuterRadius(double outerRadius)

Sets the outer radius.

getInnerRadius

public double getInnerRadius()

Gets the inner radius.

setInnerRadius

public void setInnerRadius(double innerRadius)

Sets the inner radius.

write

public void write(CH.ifa.draw.util.StorableOutput dw)

Stores the arrow tip to a StorableOutput.

Specified by:

write in interface CH.ifa.draw.util.Storable

Overrides:

write in class CH.ifa.draw.figures.AbstractLineDecoration

read

public void read(CH.ifa.draw.util.StorableInput dr)
          throws java.io.IOException

Reads the arrow tip from a StorableInput.

Specified by:

read in interface CH.ifa.draw.util.Storable

Overrides:

read in class CH.ifa.draw.figures.AbstractLineDecoration

Throws:

java.io.IOException
