public static Direction[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (Direction c : Direction.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Direction valueOf(java.lang.String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - closest
```
public static Direction closest(Vector3d vector)
```
    Gets the closest direction from the given vector. If the vector is the 0-Vector, this method returns NONE. If the vector has the same horizontal and vertical length, a horizontal direction will be returned. If the vector is halfway between two directions the clockwise next will be selected.
    
    Parameters:
    
    vector - The vector to convert to a direction
    
    Returns:
    
    The closest horizontal direction.
  - closest
```
public static Direction closest(Vector3d vector,
                                Direction.Division smallestDivision)
```
    Gets the closest direction from the given vector. If the vector is the 0-Vector, this method returns NONE. If the vector has the same horizontal and vertical length, a horizontal direction will be returned. If the vector is halfway between two directions the clockwise next will be selected.
    
    Parameters:
    
    vector - The vector to convert to a direction
    
    smallestDivision - The smallest compass division that can be returned
    
    Returns:
    
    The closest horizontal direction.
  - closestHorizontal
```
public static Direction closestHorizontal(Vector3d vector)
```
    Gets the closest horizontal direction from the given vector. If the vector is the 0-Vector (ignoring y), this method returns NONE. If the vector is halfway between two directions the clockwise next will be selected.
    
    Parameters:
    
    vector - The vector to convert to a direction
    
    Returns:
    
    The closest horizontal direction.
  - closestHorizontal
```
public static Direction closestHorizontal(Vector3d vector,
                                          Direction.Division smallestDivision)
```
    Gets the closest horizontal direction from the given vector. If the vector is the 0-Vector (ignoring y), this method returns NONE. If the vector is halfway between two directions the clockwise next will be selected.
    
    Parameters:
    
    vector - The vector to convert to a direction
    
    smallestDivision - The smallest compass division that can be returned
    
    Returns:
    
    The closest horizontal direction.
  - fromAxis
```
public static Direction fromAxis(Axis axis)
```
    Gets the direction associated with the given axis.
    
    Parameters:
    
    axis - The axis
    
    Returns:
    
    The direction

```
    Gets the direction of the axis along the given AxisDirection.
    
    Parameters:
    
    axis - The axis
    
    direction - The direction along the axis
    
    Returns:
    
    The direction
  - opposite
```
public Direction opposite()
```
    Gets the opposite direction i.e. 180 degrees from this direction.
    
    Returns:
    
    The opposite direction
  - isOpposite
```
public boolean isOpposite(Direction d)
```
    Returns whether the given direction is opposite this.
    
    Parameters:
    
    d - Direction to test
    
    Returns:
    
    True if it is opposite
  - isCardinal
```
public boolean isCardinal()
```
    Return true if the direction is of a cardinal direction (north, west east, and south).
    This evaluates as false for directions that have a non-zero Y-component.
    
    Returns:
    
    True if cardinal
  - isOrdinal
```
public boolean isOrdinal()
```
    Return true if the direction is of an ordinal direction (northwest, southwest, southeast, northeast).
    
    Returns:
    
    True if ordinal
  - isSecondaryOrdinal
```
public boolean isSecondaryOrdinal()
```
    Return true if the direction is of a secondary ordinal direction (north-northwest, north-northeast, south-southwest, etc.).
    
    Returns:
    
    True if secondary ordinal
  - isUpright
```
public boolean isUpright()
```
    Return whether Y component is non-zero.
    
    Returns:
    
    True if the Y component is non-zero
  - asOffset
```
public Vector3d asOffset()
```
    Returns the direction as a unit offset vector. This vector is also suitable as a unit direction vector.
    
    Returns:
    
    The direction as an offset
  - asBlockOffset
```
public Vector3i asBlockOffset()
```
    Returns the direction as a block offset vector. For secondary ordinals the results are approximated to the nearest block.
    The difference between this offset and asOffset() is that a block offset has unit components instead of unit length.
    
    Returns:
    
    The direction as a block offset
