Method Detail

getType

int getType()

Return an integer indicating the congruence class of rhomb.

Returns:

The congruence class of the shape this represents. It is the smallest angle in the rhomb, expressed as an integer multiple of pi/Point.N().

getAngle

int getAngle()

Return an integer indicating the angle of the rhomb.

Returns:

The angle of rotation of this.

getPoint

Point getPoint()

Getter method.

Returns:

The point.

onEdge

boolean onEdge()

Determine if this Rhomb is on the edge of the patch.

Returns:

true if it's on the edge of the patch.

collapse

void collapse()

Remove this Rhomb. This method should only be used if this is on an edge.

shift

void shift(Point vector)

Shift the Rhomb by a given vector.

Parameters:

vector - The vector by which we shift this.

getRhomb

SimplePolygon2D getRhomb()

Getter method.

Returns:

A list of polygon objects containing the 2d rhomb that this Rhomb represents. (2 coordinates.)

setScale

void setScale(double s)

Set the scale for drawing.

Parameters:

s - The new scale used to draw this rhomb.

getScale

double getScale()

Get the scale for drawing.

Returns:

The scale for drawing.

createSimpleRhomb

SimpleRhomb createSimpleRhomb()

Produce a lightweight version of this.

Returns:

A SimpleRhomb containing all the essential data from this.

gapString

java.lang.String gapString()

String representation for gap.

Returns:

A String containing various internal variables, formatted for use in gap.

postscriptString

java.lang.String postscriptString()

String representation for postscript.

Returns:

A String giving instructions for how to draw this in Postscript.
