Class ExtendableQRCodeSchemeParser

java.lang.Object

net.glxn.qrgen.core.scheme.ExtendableQRCodeSchemeParser

All Implemented Interfaces:

QRCodeSchemeParser

public class ExtendableQRCodeSchemeParser
extends Object
implements QRCodeSchemeParser

An implementation of QRCodeSchemeParser which supports the types Wifi, VCard, Girocode and URL, and may be extended by additional parsers for custom types.

In order to add a parser, you have to put a properties file named qrcode.meta into your META-INF folder, containing a comma-separated list of your parser class names assigned to the key net.glxn.qrgen.core.scheme.QRCodeSchemeParser. Let's say you have additional parsers with the full qualified names org.me.FooSchemeParser and org.me.BarSchemeParser, your qrcode.meta must have the following entry.

META-INF/qrcode.meta:

 net.glxn.qrgen.core.scheme.QRCodeSchemeParser=\
 org.me.FooSchemeParser,\
 org.me.BarSchemeParser
 

TODO: does this parser stuff make sense at all?
