Enum Constant Detail

TIMESTAMPS

public static final BinaryFormatFlag TIMESTAMPS

Include timestamps in the packed data.

NO_COMPACT

public static final BinaryFormatFlag NO_COMPACT

Do not use compact user and item IDs. This can make packing more efficient if you know that some user or item IDs do not fit in ints.

Method Detail

values

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

Returns:

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

valueOf

public static BinaryFormatFlag 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
