The implementation of clone for java object references uses the clone method of the Object class. The reading of its description in the java help page is strongly recommended.

Examples

Run this code
.jinit()
# we can run this example only if AWT is enabled
if (!nzchar(Sys.getenv("NOAWT"))) {
  p1 <- .jnew("java/awt/Point" )
  p2 <- clone( p1 )
  p2$move( 10L, 10L )
  p1$getX() 

  # check that p1 and p2 are not references to the same java object
  stopifnot( p1$getX() == 0 )
  stopifnot( p2$getX() == 10 )
}
