Class MetaDataReader

- org.apache.felix.metatype.MetaDataReader
-
@Deprecated(since="2021-05-27") public class MetaDataReader extends Object
Deprecated.The Apache Felix metatype API is deprecated, please use the OSGi metatype API instead.TheMetaDataReader
provides two methods to read meta type documents according to the MetaType schema (105.8 XML Schema). Theparse(URL)
andparse(InputStream)
methods may be called multiple times to parse such documents.While reading the XML document java objects are created to hold the data. These objects are created by factory methods. Users of this may extend this class by overwriting the the factory methods to create specialized versions. One notable use of this is the extension of the
AD
class to overwrite theAD.validate(String)
method. In this case, thecreateAD()
method would be overwritten to return an instance of the extending class.This class is not thread safe. Using instances of this class in multiple threads concurrently is not supported and will fail.
