Class QrSegment

java.lang.Object

eu.webtoolkit.jwt.thirdparty.qrcodegen.QrSegment

public final class QrSegment
extends Object

A segment of character/binary/control data in a QR Code symbol. Instances of this class are immutable. The mid-level way to create a segment is to take the payload data and call a static factory function such as QrSegment::makeNumeric(). The low-level way to create a segment is to custom-make the bit buffer and call the QrSegment() constructor with appropriate values. This segment class imposes no length restrictions, but QR Codes have restrictions. Even in the most favorable conditions, a QR Code can only hold 7089 characters of data. Any segment longer than this is meaningless for the purpose of generating QR Codes.
