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.
