jsimplify.Rd.jsimplify attempts to convert Java objects that represent
simple scalars into corresponding scalar representation in R.
.jsimplify(o, promote=FALSE)arbitrary object
logical, if TRUE then an ambiguous conversion
where the native type value would map to NA (e.g., Java
int type with value -2147483648) will be taken
to represent an actual value and will be promoted to a larger type
that can represent the value (in case of int promoted to
double). If FALSE then such values are assumed to
represent NAs.
Simple scalar or o unchanged.
If o is not a Java object reference, o is returned
as-is. If o is a reference to a scalar object (such as single
integer, number, string or boolean) then the value of that object is
returned as R vector of the corresponding type and length one.
This function is used by .jfield to simplify the results
of field access if required.
Currently there is no function inverse to this, the usual way to wrap
scalar values in Java references is to use .jnew as the
corresponding constructor.
if (FALSE) { # \dontrun{
i <- .jnew("java/lang/Integer", as.integer(10))
print(i)
print(.jsimplify(i))
} # }
