Document

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:EventFilterExample.java

public static void main(String[] args) throws Exception {
    File file = new File("text.xml");

    XMLInputFactory inputFactory = XMLInputFactory.newInstance();
    XMLEventReader reader = inputFactory.createXMLEventReader(new FileInputStream(file));

    System.out.println("Unfiltered Count = " + countEvents(reader));

    reader = inputFactory.createXMLEventReader(new FileInputStream(file));

    EventFilter filter = new ElementOnlyFilter();
    reader = inputFactory.createFilteredReader(reader, filter);

    System.out.println("Filtered Count = " + countEvents(reader));
}

From source file:MainClass.java
