All Implemented Interfaces:

Serializable, Comparable<Validity>

public enum Validity
extends Enum<Validity>

This class encapsulates the possible UTF-8 validities of a sequence of bytes

Enum Constant Detail

ASCII

public static final Validity ASCII

Pure ASCII

UNDERFLOW_R0

public static final Validity UNDERFLOW_R0

Valid UTF-8 that is not necessarily truncated and that is not pure ASCII

UNDERFLOW_R1

public static final Validity UNDERFLOW_R1

Valid UTF-8 that is truncated after the first byte in a multi-byte sequence

UNDERFLOW_R2

public static final Validity UNDERFLOW_R2

Valid UTF-8 that is truncated after the second byte in a multi-byte sequence

UNDERFLOW_R3

public static final Validity UNDERFLOW_R3

Valid UTF-8 that is truncated after the third byte in a multi-byte sequence

Method Detail

values

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

Returns:

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

valueOf

public static Validity 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

isFullyValid
