方法详细资料

file

public abstract File file()

returns a File representation of the QR code. The file is set to be deleted on exit (i.e. File.deleteOnExit()). If you want the file to live beyond the life of the jvm process, you should make a copy.

返回:

qrcode as file

file

public abstract File file(String name)

returns a File representation of the QR code. The file has the given name. The file is set to be deleted on exit (i.e. File.deleteOnExit()). If you want the file to live beyond the life of the jvm process, you should make a copy.

参数:

name - name of the created file

返回:

qrcode as file
