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 namejava.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
