Examples with ModuleWiring org.eclipse.osgi.container.ModuleWiring used on opensource projects

Example 6 with ModuleWiring

use of org.eclipse.osgi.container.ModuleWiring in project rt.equinox.framework by eclipse.

the class DependentPolicy method loadResource.

public URL loadResource(String name) {
    if (allDependents == null)
        return null;
    URL result = null;
    // size may change, so we must check it every time
    for (int i = 0; i < allDependents.size() && result == null; i++) {
        ModuleWiring searchWiring = allDependents.get(i);
        BundleLoader searchLoader = (BundleLoader) searchWiring.getModuleLoader();
