Re: Using Hivemind in an existing application

["karthik.nar" <ka...@gmail.com>]

catalin,

were you able to figure a way to use a static method in point#2 below?

2. In point two, I meant some sort of <create-object> that uses a static 
getInstance method instead of calling the constructor.

i have a requirement where i want to pass a new instance of an apache
commons Log object from the Logger in the 
    <invoke-factory>
      <construct class=blah>
         <set-object property="log"
value="instance:@org.apache.log4j.Logger@getLog()" />
      </construct>
    </invoke-factory>


I've not be able to figure out how to do it!

        <set-object property="log"
value="instance:@org.apache.log4j.Logger@getLog()" />

or

        <set-object property="log"
value="instance:org.apache.log4j.Logger.getLog()" />

or anything else?!

RE: Using Hivemind in an existing application

[James Carman <ja...@carmanconsulting.com>]

The idea Knut proposed was that you come up with a single place to ask for
your HiveMind registry...

public class HiveMindRegistry
{
  private static final Regisry instance =
RegistryBuilder.constructDefaultRegistry();

  public static Registry getInstance()
  {   
    return instance;
  }
}

Then, in your singleton service's getInstance() method:

public static MyService 
{
  public static MyService getInstance()
  {
    return ( MyService
)HiveMindRegistry.getInstance().getService(MyService.class);
  }
}

Of course, in a real dependency injection-oriented system, you'd just
declare setters for the MyService and HiveMind would inject it for you
rather than looking up the singleton using a getInstance() method.  But,
Catalin said that she wanted to gradually migrate to HiveMind, so I guess
that's not possible.
