Enum Constant Detail

COMPATIBLE_WITH_MODTIME

public static final DataFileVersionStrategy.Characteristic COMPATIBLE_WITH_MODTIME

The default version for a data file is the modtime of the file. Versions can in general be compared against modtimes.

SETTABLE

public static final DataFileVersionStrategy.Characteristic SETTABLE

Version can be explicitly set. If false, `set*` methods will always return false

STRICT

public static final DataFileVersionStrategy.Characteristic STRICT

If a file has been modified and a set* method was not called, `getVersion` will throw an error.

Method Detail

values

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

Returns:

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

valueOf

public static DataFileVersionStrategy.Characteristic 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
