  oo.Mattress1

All Implemented Interfaces:

HasHLT, PRYable

public class Mattress1
extends java.lang.Object
implements PRYable

A mattress and its orientations; the mattress's state (its orientation) is implemented with three booleans.

		To, after a ...
From		pitch	roll	yaw
FLB	HLT	FRT	HRB
FRT	HRB	FLB	HLT
HLT	FLB	HRB	FRT
HRB	FRT	HLT	FLB

The FLB, FRT, etc. codes in the table above are interpreted as follows:

Code	Meaning
B	Bottom is green
F	Foot is red
H	Head is red
L	Left is blue
R	Right is blue
T	Top is green

Constructor Summary

Mattress1()
Constructs a mattress with red-end at top, blue-end at left, and green-surface at top.

Method Summary

boolean	headRed() True iff the red end is at the top.
boolean	leftBlue() True iff the blue side is at the left.
PRYable	pitch() Pitches the thing a half-turn (180 degrees).
PRYable	roll() Rolls the thing a half-turn (180 degrees).
boolean	topGreen() True iff the green surface is on the top.
java.lang.String	toString() A string representing the orientation, matching [HF][LR][TB]. The string contains H if headRed() and F otherwise; L if leftBlue() and R otherwise; and T if topGreen() and B otherwise.
PRYable	yaw() Yaws the thing a half-turn (180 degrees).
