/** |
|
* 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). |
