我目前正在開發基於JDT的自定義重構工具。在某一點上,我希望找到所有類型的子類型,就像eclipse中的「Type Hierarchy」視圖一樣。我使用SearchEngine編寫了一個通過hierarchie的遞歸函數。這有效,但對於深層次結構來說速度緩慢。我可以使用更高效的API嗎?如何高效地查找IType的所有子類型
private Set<IType> searchForSubTypesOf(IType type, IProgressMonitor monitor) throws CoreException {
final Set<IType> result = new HashSet<IType>();
SearchPattern pattern = SearchPattern.createPattern(type, IJavaSearchConstants.REFERENCES, SearchPattern.R_EXACT_MATCH);
SearchParticipant[] participants = new SearchParticipant[] { SearchEngine.getDefaultSearchParticipant() };
IJavaSearchScope scope = SearchEngine.createHierarchyScope(inputType);
SearchRequestor requestor = new SearchRequestor() {
@Override
public void acceptSearchMatch(SearchMatch match) throws CoreException {
if (match.getAccuracy() == SearchMatch.A_ACCURATE && match.getElement() instanceof IType) {
IType subType = (IType)match.getElement();
result.add(subType);
// Recursive search for the type found
Set<IType> subTypes = searchForSubTypesOf(subType, new NullProgressMonitor());
result.addAll(subTypes);
}
}
};
new SearchEngine().search(pattern, participants, scope, requestor, monitor);
return result;
}
你們能不能考慮的類型層次的根源,看看他們是如何做的? – Kai 2013-03-25 15:23:55

謝謝!發現它:-)見下面... – 2013-03-26 13:55:50
