How to make wildcard search for repository workspaces using Plain Java API
In Eclipse I can serach for repository workspaces using a pattern including the wildcards * and ?, where * means any sequence of chars, and ? means any single char.
I tried this using plain java api, but found that it did not work.
String pattern = "abc-???_cde"; IWorkspaceSearchCriteria wsSearchCriteria = IWorkspaceSearchCriteria.FACTORY.newInstance(); wsSearchCriteria.setKind(IWorkspaceSearchCriteria.WORKSPACES); wsSearchCriteria.setPartialName(pattern);The search did not find the workspaces with names 'abc-123_cde' or 'abc-666_cde'
After some investigation I found that the eclipse client calls a Util class that converts the search pattern, before calling the API.
The conversion looks like this
switch (ch) {
case '*':
buffer.append("%");
break;
case '?':
buffer.append("_");
break;
case '%':
buffer.append("\\%");
break;
case '_':
buffer.append("\\_");
break;
case '\\':
buffer.append("\\\\");
break;
default:
buffer.append(ch);
}
So to the above search pattern should be converted to "abc-___\\_cde" then it worked just fine, and it finds both of the above workspaces,
Hope someone can make use of this information.

As explained in the question, it can be done by converting * and ? properly.
