Class DescriptorSourceFactory
public final class DescriptorSourceFactory
extends java.lang.Object
Descriptor sources are the only producers of classes implementing
the Descriptor
superinterface. There exist descriptor sources
for obtaining remote descriptor data (DescriptorCollector
) and
descriptor sources for processing local descriptor data
(DescriptorReader
and DescriptorParser
).
By default, this factory returns implementations from the library's own impl package. This may be overridden by setting Java properties, though most users will simply use the default implementations.
These properties can be used for setting the implementation:
descriptor.collector
descriptor.parser
descriptor.reader
Assuming the classpath contains the special implementation referenced, your application classes as well as a descriptor API jar the following is an example for using a different implementation of the descriptor downloader:
java -Ddescriptor.downloader=my.special.descriptorimpl.Downloader \
my.app.Mainclass
