Method Detail

values

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

Returns:

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

valueOf

public static TimeResolution 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

toMillis

public static long toMillis(TimeSpan timeSpan)

Converts to milliseconds the given timeSpan.

Parameters:

timeSpan - time duration to convert

Returns:

time duration in milliseconds

toMillis

public static long toMillis(long val,
                            TimeResolution resolution)

Converts to milliseconds the duration val, given at the TimeResolution resolution.

Parameters:

val - the duration

resolution - the precision

Returns:

time duration in milliseconds

toDate

public static Date toDate(TimeSpan timestamp)

Converts to Date the given timestamp.

Parameters:

timestamp - time duration since epoch

Returns:

the Date corresponding to the given timestamp

toDate

public static Date toDate(long timestamp,
                          TimeResolution resolution)

Converts to Date the timestamp, given at the TimeResolution resolution.

Parameters:

timestamp - time duration since epoch

resolution - the timestamp precision

Returns:

the Date corresponding to the given timestamp
