Method Detail

values

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

Returns:

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

valueOf

public static TimeUnit valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

getShortName

public java.lang.String getShortName()

Returns the short name representing this unit in a string specifying a time duration.

Returns:

the short name of this time unit.

getLongName

public java.lang.String getLongName()

Returns the long name of this time unit.

Returns:

the long name of this time unit.

toString

public java.lang.String toString()

Calls getLongName.

Overrides:

toString in class java.lang.Enum<TimeUnit>

Returns:

the result of getLongName.

getHours

public double getHours()

Returns this time unit represented in hours. This returns the number of hours corresponding to one unit.

Returns:

the time unit represented in hours.

convert

public static double convert(double value,
             TimeUnit srcUnit,
             TimeUnit dstUnit)

Converts value expressed in time unit srcUnit to a time duration expressed in dstUnit and returns the result of the conversion.

Parameters:

value - the value being converted.

srcUnit - the source time unit.

dstUnit - the destination time unit.

Returns:

the converted value.

Throws:

java.lang.NullPointerException - if srcUnit or dstUnit are null.
