------------------------------------
Summary: AXIS 2 Doc correction
Key: AXIS2-5660
URL: https://issues.apache.org/jira/browse/AXIS2-5660
Project: Axis2
Issue Type: Bug
Components: documentation
Affects Versions: 1.6.2
Reporter: Martin Gainty
Handlers and Chains can be defined to have 'per-access', 'per-request', or
'singleton' scope although the registry currently only distinguishes between
these by constructing non-singleton scope objects when requested and
constructing singleton scope objects once and holding on to them for use on
subsequent creation requests.
There are NO singleton implementations of Handlers ..here is proof:
public class FactoryRegistry {
private static volatile Map<Class, Object> table;
private static Object lockbox = new Object();
private static final Log log = LogFactory.getLog(FactoryRegistry.class);
static {
try {
init();
} catch (Throwable t){
log.error(t.getMessage(), t);
}
}
private static final void init() {
// An unsynchronized Map is used to ensure that gets are fast.
table = new HashMap<Class, Object>(64, .5f);
,,,,
table.put(HandlerInvokerFactory.class, new HandlerInvokerFactoryImpl());
}
//later on when you access HandlerInvokerFactory you get the
//SAME HandlerInvokerFactoryImpl that you instantated:
/**
* Get the factory. This may be called frequently.
* @param intface of the Factory
* @return Object that is the factory implementation for the intface
*/
public static Object getFactory(Class intface) {
Map m = table;
return m.get(intface);
}
//so the RegistryFactory exhibits Singleton like behaviour
//but what happens when I create a HandlerInvokeFactory?
package org.apache.axis2.jaxws.handler.factory.impl;
/**
* This is the default implementation of the HandlerInvokerFactory,
* and it will be registered with the FactoryRegistry.
*/
public class HandlerInvokerFactoryImpl implements HandlerInvokerFactory {
public HandlerInvoker createHandlerInvoker(MessageContext messageContext) {
return new HandlerInvokerImpl();
}
}
If this is NOT singleton which clearly it is not then you need to
correct this documentation asap
