All Implemented Interfaces:
java.io.Serializable, java.lang.Comparable<ErrorCorrectionLevel>

public enum ErrorCorrectionLevel
extends java.lang.Enum<ErrorCorrectionLevel>

See ISO 18004:2006, 6.5.1. This enum encapsulates the four error correction levels defined by the QR code standard.

Enum Constant Detail

L

public static final ErrorCorrectionLevel L
L = ~7% correction


M

public static final ErrorCorrectionLevel M
M = ~15% correction


Q

public static final ErrorCorrectionLevel Q
Q = ~25% correction


H

public static final ErrorCorrectionLevel H
H = ~30% correction

Method Detail

values

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

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

valueOf

public static ErrorCorrectionLevel 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

getBits

public int getBits()

forBits

public static ErrorCorrectionLevel forBits(int bits)
Parameters:
bits - int containing the two bits encoding a QR Code's error correction level
Returns:
ErrorCorrectionLevel representing the encoded error correction level
