All Implemented Interfaces:

Serializable

public class BarcodeException
extends Exception

Thrown when a barcode object is assigned an invalid content that cannot be encoded by the given barcode type.

Returns an exception ID from one of the three categories: Content, Checksum and Add-On. Some IDs are for general use, while others are reserved for specific barcode types.

Content related exceptions:

• CONTENT_EMPTY - Indicates empty content.
• CONTENT_INVALID - States a general invalidity of the content.
• CONTENT_NOT_DIGITS - Indicates that the content contains non-digit characters.
• CONTENT_NOT_ASCII - Indicates that the content contains non-ASCII characters.
• CONTENT_LENGTH_INVALID - Indicates an invalid content length.
• CONTENT_LENGTH_NOT_EVEN - Indicates that the content length is not even.

Checksum related exceptions:

• CHECKSUM_INVALID - Indicates an invalid checksum.

Add-On related exceptions:

• ADDON_EMPTY - Indicates empty add-on content.
• ADDON_LENGTH_INVALID - Indicates an invalid add-on length.
• ADDON_NOT_DIGITS - Indicates that the add-on content contains non-digit characters.

If you prefer to determine which of the three categories an exception belongs to, rather than handle each exception ID separately, you can use the three corresponding methods isContentRelated(), isChecksumRelated() and isAddOnRelated() provided in this class.
