Method Detail

tryConvert

public static boolean tryConvert(@Nonnull
                                 JulianDate value,
                                 @Nonnull
                                 TimeStandard to,
                                 @Nonnull
                                 JulianDate[] result)

Tries to convert the specified JulianDate to the specified TimeStandard, returning success or failure.

Parameters:

value - The JulianDate to convert.

to - The TimeStandard to convert value to.

result - On input, an array with one element. On return, the array is populated with the resulting JulianDate equivalent to value in the new TimeStandard.

Returns:

true if value could be converted to the requested TimeStandard to; otherwise false.

convert

@Nonnull
public static JulianDate convert(@Nonnull
                                           JulianDate value,
                                           @Nonnull
                                           TimeStandard to)

Converts the specified JulianDate to the specified TimeStandard.

Parameters:

value - The JulianDate to convert.

to - The TimeStandard to convert value to.

Returns:

A JulianDate equivalent to value in the new TimeStandard.

getConversionDistance

public static int getConversionDistance(@Nonnull
                                        TimeStandard from,
                                        @Nonnull
                                        TimeStandard to)

Gets the number of intermediate conversions that must be done to convert from from to to. For example, if a conversion function is defined to directly convert between the time standards, 1 will be returned. If the two standards are identical, 0 will be returned. If no conversion exists at all, Integer.MAX_VALUE will be returned.

Parameters:

from - The source time standard.

to - The destination time standard.

Returns:

The number of conversion functions that must be invoked to convert between the formats.

registerConversion

public static void registerConversion(@Nonnull
                                      TimeStandard from,
                                      @Nonnull
                                      TimeStandard to,
                                      @Nonnull
                                      FormatConversionCallback<JulianDate,TimeStandard> conversion)

Registers a new conversion between time standards.

Parameters:

from - The time standard that the conversion method converts from.

to - The time standard that the conversion method converts to.

conversion - The conversion method.

isConversionDefined

public static boolean isConversionDefined(@Nonnull
                                          TimeStandard from,
                                          @Nonnull
                                          TimeStandard to)

Determines if a conversion between two TimeStandards has been defined.

Parameters:

from - The source time standard.

to - The destination time standard.

Returns:

true if a conversion is defined; otherwise false.
