abstract class ByteStream { .. }

class SomeClass { 
    void someMethod() { 
        this.getStream().writeByte(13); // call on interface or abstract class 
    }
    ByteStream getStream() { .. } 
}

// later in code

// does this avoid dynamic dispatch inside "SomeClass:someMethod" ?
SomeClass clsA = new SomeClass() {

SomeClass clsB = new SomeClass() {

Not very sure. It definitely does not work when you compile SomeClass::someMethod in isolation. It probably does not also work when you compile SomeClass_anonymous1::someMethod, because the type profile is probably bound to the callsite in SomeClass::someMethod. You just have to check it yourself :)

:-) i will some day, thanks for your statement
