XML - Stream of event Programming Model
Table of Contents
1 - About
Streaming refers to a programming model in which XML infosets
- are transmitted and parsed serially:
- at application runtime,
- often in real time,
- and often from dynamic sources
- whose contents are not precisely known beforehand.
Streaming provides high performance (smaller memory footprint, reduced processor requirements).
As you can only see the XML infosets state at one location at a time in the document, you need to know what processing you want to do before reading the XML document.
Streaming models are particularly useful when your application:
- has strict memory limitations (cellphone, …)
- needs to process several requests simultaneously (application server)
