- * The <code>StreamGenerator</code> is a class that reads XML from a request
InputStream
- * and generates SAX Events.
- * For the POST requests with mimetype of application/x-www-form-urlencoded the xml
data is
- * expected to be associated with the name specified in the sitemap parameter.
- * For the POST requests with mimetypes: text/plain, text/xml, application/xml the
xml data is in the body of teh POST
- * request and its length is specified by the value returned by getContentLength()
method.
- * The StreamGenerator uses helper org.apache.cocoon.util.PostInputStream class for
InputStream reading operations.
- * At the time that Parser is reading the data out of InputStream - Parser has no
knowledge about the length of data to be read.
- * The only way to signal to the Parser that all data was read from the InputStream
is to control reading operation - PostInputStream- and to return to
- * the requestor -1 when the number of bytes read is equal to the
getContentLength() value.
