Constructor Detail

Nutation

public Nutation(double longitude,
                double obliquity,
                double omega)

Initializes a new Nutation with specified angles in longitude and in obliquity.

Parameters:

longitude - The nutation in longitude, in radians

obliquity - The nutation in obliquity, in radians

omega - The longitude of the mean ascending node of the lunar orbit on the ecliptic plane measured from the mean equinox of date, in radians

Method Detail

getLongitude

public final double getLongitude()

Gets the nutation in longitude, in radians.

getObliquity

public final double getObliquity()

Gets the nutation in obliquity, in radians.

getOmega

public final double getOmega()

Gets the longitude of the mean ascending node of the lunar orbit on the ecliptic plane measured from the mean equinox of date.

equalsType

public final boolean equalsType(Nutation other)

Indicates whether another instance of this type is exactly equal to this instance.

Specified by:

equalsType in interface IEquatable<Nutation>

Parameters:

other - The instance to compare to this instance.

Returns:

true if other represents the same value as this instance; otherwise false.

equals

public boolean equals(Object obj)

Indicates whether another object is exactly equal to this instance.

Overrides:

equals in class Object

Parameters:

obj - The object to compare to this instance.

Returns:

true if obj is an instance of this type and represents the same value as this instance; otherwise false.

hashCode

public int hashCode()

Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table.

Overrides:

hashCode in class Object

Returns:

A hash code for the current object.

equals

public static boolean equals(Nutation left,
                             Nutation right)

Returns true if the two instances are exactly equal.

Parameters:

left - The instance to compare to right.

right - The instance to compare to left.

Returns:

true if left represents the same value as right; otherwise false.

notEquals

public static boolean notEquals(Nutation left,
                                Nutation right)

Returns true if the two instances are not exactly equal.

Parameters:

left - The instance to compare to right.

right - The instance to compare to left.

Returns:

true if left does not represent the same value as right; otherwise false.
