Overview (Javolution Core (Java) 6.0.0 API)

Packages
Package	Description
javolution.context	Run-time `contexts` to facilitate separation of concerns and achieve higher level of performance and flexibility.
javolution.io	Utility classes for input and output such as `Struct` and `Union` for direct interoperability with C/C++.
javolution.lang	Fundamental classes, interfaces and annotations.
javolution.test	Testing tools for validation and performance.
javolution.text	Text handling package.
javolution.util	High-performance collection classes with `worst case execution time behavior` documented.
javolution.util.function	Basic functions for lambda expressions and method references.
javolution.util.service	Service interfaces to be implemented by `javolution.util.*` collections and collections views.
javolution.xml	Support for the encoding of objects, and the objects reachable from them, into `XML`; and the complementary reconstruction of the object graph from `XML`.
javolution.xml.sax	`SAX2` and high-performance `SAX2-Like` parsers.
javolution.xml.stream	StAX-like XML readers/writers which do not require object creation (such as String) and are consequently faster than standard StAX.
javolution.xml.ws	Classes and interfaces to create and handle web services.

Overview:

Although Java^TM has been very successful on the server-side; It has few shortcomings limiting its adoption for others domains such as real-time, embedded or high-performance applications. For these, the Javolution library provides important "pieces" missing from the Java^TM core library and making the Java^TM platform even more attractive.

Usage:

Javolution can be used as a standard OSGi bundle.

import org.osgi.framework.*;
import org.osgi.util.tracker.ServiceTracker;
public class MyActivator implements BundleActivator { 
    ServiceTracker<XMLInputFactory, XMLInputFactory> tracker; 
    public void start(BundleContext bc) throws Exception {
        tracker = new ServiceTracker<>(bc, XMLInputFactory.class, null);
        tracker.open();
        parse();
    }
    public void stop(BundleContext bc) throws Exception {
        tracker.close();
    }
    public void parse() throws XMLStreamException {
        XMLInputFactory factory = tracker.getService();  
        factory.setProperty(XMLInputFactory.IS_COALESCING, true); // Configures.

        // Instantiates a new reader.
        String xml = "<test>This is a test</test>";
        CharSequenceReader in = new CharSequenceReader().setInput(xml);
        XMLStreamReader reader = factory.createXMLStreamReader(in);
       
        // Parses XML.
       while (reader.hasNext()) {
          int eventType = reader.next();
          if (eventType == XMLStreamConstants.CHARACTERS) {
              System.out.println(reader.getText());
          }
       }
 
       // Closes the reader which may be recycled back to the factory.
      reader.close();
   }          
}

Or as a standard Java library (does not require OSGi runtime).

import javolution.osgi.internal.OSGiServices;
public class Main {
    public static void main(String[] args) throws XMLStreamException {
        XMLInputFactory factory = OSGiServices.getXMLInputFactory();  
        factory.setProperty(XMLInputFactory.IS_COALESCING, true); // Configures.
        
        // Instantiates a reader.
        String xml = "<test>This is a test</test>";
        CharSequenceReader in = new CharSequenceReader().setInput(xml);
        XMLStreamReader reader = factory.createXMLStreamReader(in);
        
        // Parses XML.
        while (reader.hasNext()) {
           int eventType = reader.next();
           if (eventType == XMLStreamConstants.CHARACTERS) {
              System.out.println(reader.getText());
           }
        }
 
        // Closes the reader which may be recycled back to the factory.
        reader.close();
    }
}

Services:

Javolution publishes the following OSGi services.

Published Service	Description
`XMLInputFactory`	StAX-like version of javax.xml.stream.XMLInputFactory avoiding `String` allocations.
`XMLOutputFactory`	StAX-like version of javax.xml.stream.XMLOutputFactory using `CharSequence` instead of `String`

These services can be accessed through the standard OSGi registry or using javolution.osgi.internal.OSGiServices when running outside OSGi.

Javolution listen to the following OSGi services.

Subscribed Service	Description
`org.osgi.service.log.LogService`	OSGi service to log messages.
`LogContext`	Service to support asynchronous logging.
`ConcurrentContext`	Service to support concurrent executions.
`LocalContext`	Service to support locally scoped settings.
`SecurityContext`	Service granting security authorizations.
`TextContext`	Service to support text parsing/formatting.
`XMLContext`	Service to support XML serialization/deserialization.
