\title{
Object cloner
}
\description{
Generic function to clone objects
}
\usage{
clone(x, ...)
}
\section{Methods}{
\describe{
\item{clone}{\code{signature(x = "jobjRef")}: clone a java object reference (must implement Cloneable) }
\item{clone}{\code{signature(x = "jarrayRef")}: clone a java rugged array (not yet implemented) }
\item{clone}{\code{signature(x = "jrectRef")}: clone a java rectangular array (not yet implemented) }
}
}
\arguments{
\item{x}{An object to clone}
\item{\dots}{Further arguments, ignored}
}
\value{
A clone of the object
}
\section{Warning}{
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 \emph{strongly} recommended.
}
\examples{
\dontshow{.jinit()}
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 )
