| Loading operator extension from Jar file [message #1734022] |

Dear all.
I'm writing an library that is providing math primitives such as vectors, matrices, etc.
Currently, I have hard-coded the Xbase operators in the primitives by creating functions like:
public Vector operator_plus(Vector a) {
Vector v = new Vector(this);
v.add(a);
return v;
}
The use of the operators in my DSL is working.
Now, I would like to move these functions into a static utility class similar to the MapExtensions provided by Xtext.
The problem is:
is it possible for the DSL compiler to automatically load this extension when the Jar file of my math library is present in the classpath of the compiled project?
I would like to find some automatic approach that do not requires to change neither the compiler's configuration nor its code.
I know how to add an extension in the DSL compiler. But I would like to know if the Xtext provides tools for dynamic loading.
All the best.
Stéphane.

Thank you for your reply.
Are the ImplicityImportedFeatures or StaticImplicitMethodsFeatureForTypeProvider able to dynamically load the extensions by reading the MANIFEST file of a JAr file in the classpath.
In other words, is it possible to implicitly load features stored in a Jar file, just by adding this Jar file.
If not, I should specialize ImplicityImportedFeatures or StaticImplicitMethodsFeatureForTypeProvider in my DSL compiler.
All the best.
Stéphane.
