Introduction

The QR Invoice Library provides a domain model that represents the QR Invoice as a whole as defined in the official specification.

The root entity is ch.codeblock.qrinvoice.model.QrInvoice. Although it is possible to create the QrInvoice object graph by hand we do not recommend to do so. Instead we advise to use the ch.codeblock.qrinvoice.model.builder.QrInvoiceBuilder. The QrInvoiceBuilder does also implicitly perform validation of the given input.

Once the QrInvoice has been built, it can then be used to generate the required product, such as:

  • Swiss Payments Code (String)

  • QR Code (Image)

  • Payment Part (Document)

Please see the Examples.
