Examples of org.eclipse.jdt.core.search.IJavaSearchScope

org.eclipse.jdt.core.search.IJavaSearchScope
An IJavaSearchScope defines where search result should be found by a SearchEngine. Clients must pass an instance of this interface to the search(...) methods. Such an instance can be created using the following factory methods on SearchEngine: createHierarchyScope(IType), createJavaSearchScope(IResource[]), createWorkspaceScope(), or clients may choose to implement this interface.

                    methodName + (project != null ? " in " + project.getProject().getName() : ""), 100);            
            IJavaSearchScope searchScope = getSearchScope(project);
            // This is kind of hacky: we need to make up a string name for the search to work right
