Method Detail

values

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

Returns:

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

valueOf

public static TimeSystem 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

getKey

public String getKey()

Get the key for the system.

Returns:

key for the system

parseTimeSystem

public static TimeSystem parseTimeSystem(String s)
                                  throws OrekitIllegalArgumentException

Parse a string to get the time system.

The string must be the time system.

Parameters:

s - string to parse

Returns:

the time system

Throws:

OrekitIllegalArgumentException - if the string does not correspond to a time system key

getTimeScale

public TimeScale getTimeScale(TimeScales timeScales)

Get the time scale corresponding to time system.

Parameters:

timeScales - the set of time scales to use

Returns:

the time scale corresponding to time system in the set of time scales
