Class SearchEngine

java.lang.Object
  org.eclipse.jdt.core.search.SearchEngine

public class SearchEngine
extends java.lang.Object

A SearchEngine searches for Java elements following a search pattern. The search can be limited to a search scope.

Various search patterns can be created using the factory methods SearchPattern.createPattern(String, int, int, int), SearchPattern.createPattern(IJavaElement, int), SearchPattern.createOrPattern(SearchPattern, SearchPattern).

For example, one can search for references to a method in the hierarchy of a type, or one can search for the declarations of types starting with "Abstract" in a project.

This class may be instantiated.

createJavaSearchScope

public static IJavaSearchScope createJavaSearchScope(IJavaElement[] elements)

public void searchDeclarationsOfSentMessages(IWorkspace workspace,
                                             IJavaElement enclosingElement,
                                             IJavaSearchResultCollector resultCollector)
                                      throws JavaModelException

Deprecated. Use searchDeclarationsOfSentMessages(IJavaElement, SearchRequestor, IProgressMonitor) instead.

Searches for all declarations of the methods invoked in the given element. The element can be a compilation unit, a source type, or a source method. Reports the method declarations using the given collector.

Consider the following code:

                class A {
                        void foo() {};
                        void bar() {};
                }
                class B extends A {
                        void foo() {};
                }
                class X {
                        void test() {
                                A a = new B();
                                a.foo();
                                B b = (B)a;
                                b.bar();
                        };
                }
 

then searching for declarations of sent messages in method X.test() would collect the methods A.foo(), B.foo(), and A.bar().

Parameters:

workspace - the workspace

enclosingElement - the method, type, or compilation unit to be searched in

resultCollector - a callback object to which each match is reported

Throws:

JavaModelException - if the search failed. Reasons include:

• the element doesn't exist
• the classpath is incorrectly set
