Overview
Java Model
Java model is a lightweight model for views.
Search Engine
Indexes of declarations, references and type hierarchy relationships.
Using the APIs, an example
Create a search pattern:
SearchPattern pattern = SearchPattern.createPattern( "foo(*) int", IJavaSearchConstants.METHOD, IJavaSearchConstants.DECLARATIONS, SearchPattern.R_PATTERN_MATCH );
Create a search scope:
IJavaSearchScope scope = SearchEngine.createWorkspaceScope();
Collect results using SearchRequestor subclass:
SearchRequestor requestor = new SearchRequestor() {
public void acceptSearchMatch(SearchMatch match) {
System.out.println(match.getElement());
}
};
Start search:
new SearchEngine().search(
pattern,
new SearchParticipant[] { SearchEngine.getDefaultSearchParticipant()},
scope,
requestor,
null /*progress monitor*/
);
AST
Precise, fully resolved compiler parse tree.
