Interface SourceLevelQueryImplementation2

public interface SourceLevelQueryImplementation2

Permits providers to return specification source level of Java source file.

A default implementation is registered by the org.netbeans.modules.java.project module which looks up the project corresponding to the file (if any) and checks whether that project has an implementation of this interface in its lookup. If so, it delegates to that implementation. Therefore it is not generally necessary for a project type provider to register its own global implementation of this query, if it depends on the Java Project module and uses this style.

1.30
