Re: [jdt-dev] Figuring out a Type is forbidden or not
|
it depends on which rule defines "forbidden"
In the olden days, we only had our own access rules defined as patterns attached
to classpath entries. The key abstraction here is
org.eclipse.jdt.core.IAccessRule. I'm not aware of any API that actually
interprets these rules for a given type.
In a modular world (JRE 9+), classes are "forbidden", when their package is not
exported from the enclosing module, or exported with restrictions. This
information can be accessed similar to this snippet:
IType type ...
IPackageFragmentRoot pfr = type.getAncestor(IJavaElement.PACKAGE_FRAGMENT_ROOT)
IModuleDescription mod = pfr.getModuleDescription();
String[] exported = mod.getExportedPackageNames(null); // exported to all
String given = type.getPackageFragment().getElementName();
// does exported contain given?

Hi All,
On a plugin i'm working on i want to check if the given type is forbidden or
not, like a class from com.sun package. Is there a JDT API for this ?
