Re: [eclipse-dev] Registering Extensions dynamically to eclipse extensio

["Thomas Watson" <tjwatson@xxxxxxxxxx>]

I have not really used the dynamic contributions
stuff in the extension registry.  But I do know there is a testcase
that "tests" it at:

http://git.eclipse.org/c/platform/eclipse.platform.runtime.git/tree/tests/org.eclipse.core.tests.runtime/src/org/eclipse/core/tests/internal/registry/ContributorsTest.java

Perhaps having a look at that may help.
 I'm fairly certain you should not be using reflection to do this.

Registering Extensions dynamically to eclipse        extension
registry

Hello devs,

Im trying to do subject as follows,

InputStream inputStream = generateInputStream(displayName,
bundle);
String bundleIdStr = String.valueOf(bundle.getBundleId());
String bundleName = bundle.getSymbolicName();
IContributor contributor = new RegistryContributor(bundleIdStr,
bundleName, null, null);
@SuppressWarnings("restriction")
ExtensionRegistry extensionRegistry = (ExtensionRegistry)
Platform.getExtensionRegistry();

@SuppressWarnings("restriction")
Field declaredField = ExtensionRegistry.class.getDeclaredField("masterToken");
declaredField.setAccessible(true);
Object masterToken = declaredField.get(extensionRegistry);

@SuppressWarnings("restriction")
boolean addContribution = extensionRegistry.addContribution(inputStream,
ContributorFactoryOSGi.createContributor(bundle42), false,
null, null, masterToken);

The method "extensionRegistry.addContribution"
return true, but when I iterate over the registered items for the particular
extensions point after this method, I'm unable to find
this registration I did dynamically.

If it returns true does not that mean that the dynamic
registration was successful?
Why am I not able to see it in the ExtensionRegistry?

Appreciate your feedback..
