Subject Re: svn commit: r771942 - in /geronimo/sandbox/blueprint/blueprint-core/src: main/java/org/apache/geronimo/blueprint/context/ test/java/org/apache/geronimo/blueprint/ test/resources/
Date Wed, 06 May 2009 03:39:53 GMT
I ran into a problem with ObjectGraph and 'prototype' scoped
components where it was creating too many instances unnecessarily. If
a component was in the repository, was in 'prototype' scope, and it
was referenced by some other component, an instance of it was
unnecessary pre-created by the ObjectGraph. ObjectGraph was really
designed to work with 'singleton' scoped components and the
'prototype' scope didn't really mix. Now, everything is done on
demand, in the right order, and just the right number of instances is
created.
As to circular dependencies, they are still caught but slightly later
at creation/injection time. See
org.apache.xbean.recipe.DefaultExecutionContext. Either way, we will
need to allow for some circular dependencies in the future so I'm sure
there will be more changes in this area in our or xbean-reflect code.
