public final class ToUnknownStream

extends SerializerBase

This class wraps another SerializationHandler. The wrapped object will either handler XML or HTML, which is not known until a little later when the first XML tag is seen. If the first tag is then the wrapped object is an HTML handler, otherwise it is an XML handler. This class effectively caches the first few calls to it then passes them on to the wrapped handler (once it exists). After that subsequent calls a simply passed directly to the wrapped handler. The user of this class doesn't know if the output is ultimatley XML or HTML. This class is not a public API, it is public because it is used within Xalan.

Usage:

**For internal use only**
