[jboss-dev-forums] [Design the new POJO MicroContainer] - Temp include/exclude filter set in Module
To be able to dynamically (per deployment unit) filter out which resources we check in
Module::visit, I need some extension/hook to the current code.
The issue came up here, where the user explicitly doesn't want to check some apps
libs:

I was thinking of something in this way - in my GenericAnnotationDeployer:
| private ResourceFilter resourceFilter;
| private ClassFilter includedFilter;
| private ClassFilter excludedFilter;
|
| /**
| * Get filter.
| * Try attachment first, then deployer's filter.
| *
| * @param unit the deployment unit
| * @param expectedClass the expected class
| * @param suffix the suffix
| * @param defaultValue the default value
| * @return found filter or null
| */
| protected static <T> T getFilter(DeploymentUnit unit, Class<T>
expectedClass, String suffix, T defaultValue)
| {
| String name = expectedClass.getName() + "." + (suffix != null ? suffix
: "");
| T result = unit.getAttachment(name, expectedClass);
| if (result == null)
| result = defaultValue;
| return result;
| }
|
| protected GenericAnnotationResourceVisitor
createGenericAnnotationResourceVisitor(DeploymentUnit unit, ClassPool pool, ClassLoader
classLoader)
| {
| GenericAnnotationResourceVisitor visitor =
super.createGenericAnnotationResourceVisitor(unit, pool, classLoader);
| ResourceFilter filter = getFilter(unit, ResourceFilter.class, null,
resourceFilter);
| if (filter != null)
| visitor.setResourceFilter(filter);
| return visitor;
| }
|
| protected Module prepareModule(DeploymentUnit unit, Module original)
| {
| ClassFilter included = getFilter(unit, ClassFilter.class, "included",
includedFilter);
| ClassFilter excluded = getFilter(unit, ClassFilter.class, "excluded",
excludedFilter);
| // TODO - temp set this two
| return super.prepareModule(unit, original);
| }
|
Since actual Module::visit is implemented in some impl detail class, I cannot do this via
delegation/wrapper pattern, since I cannot override/delegate all the needed methods to
underlying Module.
What can/should be done?
