stuhood / private final vs private[this] vs private
Last active August 29, 2015 13:57
The differences between `private final` and `private[this]` seem to be that: 1) the scala compiler will inline `private final`, 2) the accessor method for the field is generated, but also marked final.
// private[this] val yo = "yo"
$ javap -c -private -classpath . BlahThis
Compiled from "blah.scala"
public class BlahThis {
private final java.lang.String yo;
public java.lang.String toString();
Code:
0: aload_0
1: getfield #14 // Field yo:Ljava/lang/String;

scala> def inf(i: Long = 0): Stream[Long] = Stream.cons(i, inf(i+1))
inf: (i: Long)Stream[Long]
scala> val iterable: Iterable[Long] = inf()
iterable: Iterable[Long] = Stream(0, ?)
scala> inf().drop(Int.MaxValue).take(10): Iterable[Long]
res3: Iterable[Long] = Stream(2147483647, ?)
