    • Method Detail

      • getDescription

        public String getDescription()
        A description of the io component. The description should contain the file format and the classes that can be managed.

        getDescription in interface IO
        Overrides:
        getDescription in class IOImpl
        Returns:

        public String getName()

        getName in interface IO
        Returns:
        Returns the name of the io component.

        A typical implementation looks like: 

         public boolean isHandlerFor(Class value) {
        if (DataObject.class.isAssignableFrom(value))
                return true;
        return false;
 }
        Specified by:
        isHandlerFor in interface IO
        Parameters:
        value - The class that has to be checked.
        Returns:
        Results true if the class can oeprate with the given class.

      • store

        public void store​(Object value,
                  XMLSchemaBasedWriter writer)
           throws CakeIOException
        To embed xml writers into another one it must be possible to specify the parent XMLSchemaBasedWriter as well as a prefix that should be probably used. If a parent writer is specified, no header will be written.

        If the writer does not support XML writing, the writer should throw an UnsupportedOperationException. 

         public void store(Object value, String prefix, XMLWriter writer) throws CakeIOException {
        throw new UnsupportedOperationException();
 }
        Specified by:
        store in class XMLWriterImpl
        Parameters:
        value - a Object object
        writer - A parent writer that is used.
        Throws:
        CakeIOException - if any.
