Implementing Domain-Specific Languages with Xtext and Xtend - Second Edition

Classes of the same package

Just like in Java, SmallJava classes should be able to refer to external classes in the same package without importing the package. However, this is not yet the case in the current implementation. For example, given the following two SmallJava files, they are not able to refer to each other without an explicit import, although they are in the same package:

// first file
package my.pack;

class A {
  B b;
}

// second file
package my.pack;

class B extends A {}

To solve this problem, we need to go back to our custom SmallJavaImportedNamespaceAwareLocalScopeProvider that we implemented in section Default imports. The idea is to customize internalGetImportedNamespaceResolvers so that when the context is a SmallJava program then ...
