public abstract class CMSOutputStream
This abstract class is the superclass of all classes that implement an output stream filter for creating CMS Objects. A CMSOutputStream
writes its output in the form of a CMS ContentInfo structure in one pass, eliminating the necessity to accumulate all of the input data before writing any output.
In the case where a CMSOutputConnector
is provided instead of a CMSOutputStream
, only the exposed content i.e. the Content field of the ContentInfo structure minus the explicit [0] tag is written to the underlying output stream.
IMPORTANT: This class generates large CMS Objects more efficiently (Java VM memory usage) than the CMSContentInfo
class.
