ArrowTip

public ArrowTip()

ArrowTip

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

Constructs an arrow tip with the given angle and 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 AbstractLineDecoration

write

public void write(StorableOutput dw)

Stores the arrow tip to a StorableOutput.

Specified by:

write in interface Storable

Overrides:

write in class AbstractLineDecoration

read

public void read(StorableInput dr)
          throws java.io.IOException

Reads the arrow tip from a StorableInput.

Specified by:

read in interface Storable

Overrides:

read in class AbstractLineDecoration

Throws:

java.io.IOException

setAngle

protected void setAngle(double newAngle)

Sets point angle 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.

getAngle

protected double getAngle()

Returns point angle 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.

setInnerRadius

protected void setInnerRadius(double newInnerRadius)

Sets the inner radius

getInnerRadius

protected double getInnerRadius()

Returns the inner radius

setOuterRadius

protected void setOuterRadius(double newOuterRadius)

Sets the outer radius

getOuterRadius

protected double getOuterRadius()

Returns the outer radius
