net.cscott.sdr.calls

This package contains the square dance choreography engine, and the basic types and interfaces required to communicate with it.

Uses of Rotation in net.cscott.sdr.calls

Subclasses of Rotation in net.cscott.sdr.calls

class

ExactRotation Rotations are represented as fractions, where '0' is facing north (away from the caller), and '1/4' is facing east.

Fields in net.cscott.sdr.calls declared as Rotation

Rotation	Position.facing Facing direction.
Rotation	DancerPath.rollDir The rollDir and sweepDir may be zero.
Rotation	DancerPath.sweepDir The rollDir and sweepDir may be zero.

Methods in net.cscott.sdr.calls that return Rotation

Rotation	Rotation.add(Fraction f) Add the given amount to this rotation direction.
static Rotation	Rotation.create(Fraction amount, Fraction modulo)
static Rotation	Rotation.fromAbsoluteString(String s) Converts a string (one of n/s/e/w, ne/nw/se/sw) to the appropriate rotation object.
Rotation	Rotation.negate() Negate this rotation (mirror image).
Rotation	Rotation.normalize() Normalize rotation to the range 0-modulus.
Rotation	Rotation.subtract(Fraction f) Subtract the given amount from this rotation direction.

Methods in net.cscott.sdr.calls with parameters of type Rotation

boolean

Rotation.includes(Rotation r) Returns true iff all the rotations possible with the given r are included within the set of rotations possible with this.

Constructors in net.cscott.sdr.calls with parameters of type Rotation
