This is a copy of the Xerces-2J class org.apache.xerces.dom.DOMOutputImpl.java
This class represents an output destination for data.
This interface allows an application to encapsulate information about an
output destination in a single object, which may include a URI, a byte stream
(possibly with a specifiedencoding), a base URI, and/or a character stream.
The exact definitions of a byte stream and a character stream are binding
dependent.
The application is expected to provide objects that implement this interface
whenever such objects are needed. The application can either provide its
own objects that implement this interface, or it can use the generic factory
method DOMImplementationLS.createLSOutput() to create objects that
implement this interface.
The DOMSerializer will use the LSOutput object to determine where to
serialize the output to. The DOMSerializer will look at the different
outputs specified in the LSOutput in the following order to know which one
to output to, the first one that data can be output to will be used:
1.LSOutput.characterStream
2.LSOutput.byteStream
3.LSOutput.systemId
LSOutput objects belong to the application. The DOM implementation will
never modify them (though it may make copies and modify the copies,
if necessary).
