Examples of org.jruby.runtime.opto.Invalidator

org.jruby.runtime.opto.Invalidator
Abstract invalidator of "something". An example would be a global invalidator for cached constants. How invalidation is performed is considered to be opaque. To invalidate, call #invalidate. To get data associated with the invalidation, use getData; the meaning of this data is Invalidator-implementation-specific. In the case of JSR-292's SwitchPoint, this would return a SwitchPoint to be used for guarding e.g. a cached constant value.

        // Call const_missing or cache
        if (constant == null) {
            constant = module.callMethod(context, "const_missing", runtime.fastNewSymbol(constName));
        } else {
            // recache
            Invalidator invalidator = runtime.getConstantInvalidator(constName);
            cache = new ConstantCache((IRubyObject)constant, invalidator.getData(), invalidator);
        }


        return constant;
    }
