Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

Usage

From source file:MainClass.java

public static void main(String[] args) throws Exception {
    XMLInputFactory inputFactory = XMLInputFactory.newInstance();

        public boolean accept(XMLEvent event) {
            return false;
        }//from  w ww  .  j  a  v  a2  s .  com
