Method Detail

values

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

Returns:

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

valueOf

public static Granularity 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

getInMillis

public int getInMillis()

Duration of a corresponding bin in milliseconds.

Returns:

bin length in milliseconds

getBinId

public int getBinId(long timeMillis)

Bin id for an epoch time is the epoch time in the corresponding granularity.

Parameters:

timeMillis - epoch time in milliseconds

Returns:

the bin id

toString

public String toString()

Overrides:

toString in class Enum<Granularity>

fromMillis

public static Granularity fromMillis(long millis)
