Method Detail

values

public static KeplerianCoordinate[] 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 (KeplerianCoordinate c : KeplerianCoordinate.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static KeplerianCoordinate valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getStateVectorIndex

public int getStateVectorIndex()

Gets the index of the coordinate in the state vector array.

Specified by:

getStateVectorIndex in interface OrbitalCoordinate

Returns:

the index of the coordinate in the state vector array.

getOrbitType

public OrbitType getOrbitType()

Gets the orbit type to which this orbital coordinate is related.

Specified by:

getOrbitType in interface OrbitalCoordinate

Returns:

the orbit type to which this orbital coordinate is related

valueOf

public static KeplerianCoordinate valueOf(int stateVectorIndex,
                                          PositionAngle positionAngle)

Gets the coordinate type associated with a given state vector index.

Parameters:

stateVectorIndex - the state vector index

positionAngle - the position angle type (only used for the anomaly)

Returns:

the coordinate type associated with the provided state vector index

Throws:

IllegalArgumentException - if the provided state vector index is not between 0 and 5 (included)
