Method Detail

find

void find(BundleContext context,
        java.util.Collection<Bundle> bundles)

Find hook method. This method is called for the following:

• Bundle find operations using BundleContext.getBundle(long) and BundleContext.getBundles() methods. The find method can filter the result of the find operation. Note that a find operation using the BundleContext.getBundle(String) method does not cause the find method to be called.
• Bundle install operations when an existing bundle is already installed at a given location. In this case, the find method is called to determine if the context performing the install operation is able to find the bundle. If the context cannot find the existing bundle then the install operation must fail with a BundleException.REJECTED_BY_HOOK exception.

Parameters:

context - The bundle context of the bundle performing the find operation.

bundles - A collection of Bundles to be returned as a result of the find operation. The implementation of this method may remove bundles from the collection to prevent the bundles from being returned to the bundle performing the find operation. The collection supports all the optional Collection operations except add and addAll. Attempting to add to the collection will result in an UnsupportedOperationException . The collection is not synchronized.
