Packages that use Rotation

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.

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.
static Rotation	Rotation.union(List<Rotation> rots)
Rotation	Rotation.union(Rotation r) Return a Rotation which includes all the directions represented by this and the specified Rotation.

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

static Position	Position.getGrid(int x, int y, Rotation r, Position.Flag... flags) Returns a position corresponding to the standard square dance grid. 0,0 is the center of the set, and odd coordinates between -3 and 3 correspond to the standard 4x4 grid.
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.
Position	Position.relocate(Fraction x, Fraction y, Rotation facing) Move a Position, preserving its flags.
Rotation	Rotation.union(Rotation r) Return a Rotation which includes all the directions represented by this and the specified Rotation.

Position(Fraction x, Fraction y, Rotation facing, Set<Position.Flag> flags)
Create a Position object from the given x and y coordinates, facing Rotation, and the given Set of Position.Flags.

Position(int x, int y, Rotation facing, Position.Flag... flags)
