Converts Java object to a simple scalar if possible
.jsimplify attempts to convert Java objects that represent
simple scalars into corresponding scalar representation in R.
- arbitrary object
- logical, if
TRUEthen an ambiguous conversion where the native type value would map to
inttype with value -2147483648) will be taken to represent an actual value and will be promoted to a larger
o is not a Java object reference,
o is returned
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
- Simple scalar or
i <- .jnew("java/lang/Integer", as.integer(10)) print(i) print(.jsimplify(i))
