NAME

Statistics::R::REXP::EmptyEnvironment - the empty R environment (emptyenv())

VERSION

version 0.10

SYNOPSIS

    use Statistics::R::REXP::EmptyEnvironment
    
    my $env = Statistics::R::REXP::EmptyEnvironment->new;
    print $env->name;

DESCRIPTION

An object of this class represents a special R environment (ENVSXP) that is at the base of the environment enclosure hierarchy, which has no parent.env and into which nothing can be assigned.

You shouldn't create instances of this class, it exists mainly to handle deserialization of emptyenv() by the IO classes.

METHODS

Statistics::R::REXP::EmptyEnvironment inherits from Statistics::R::REXP::Environment, with the added restriction that it doesn't have attributes, enclosure, or any contents. Trying to create an EmptyEnvironment instance that doesn't follow this restriction will raise an exception.

ACCESSORS

name

Just as in R, the name of the EmptyEnvironment is "R_EmptyEnv".

BUGS AND LIMITATIONS

Classes in the REXP hierarchy are intended to be immutable. Please do not try to change their value or attributes.

There are no known bugs in this module. Please see Statistics::R::IO for bug reporting.

SUPPORT

See Statistics::R::IO for support and contact information.
