NAME
Statistics::R::IO::Base - Common object methods for processing R files
VERSION
version 1.0002
SYNOPSIS
use Statistics::R::IO::Base; # $f is an instance of Base $f->does('Statistics::R::IO::Base'); my $var = $rds->read; $f->close;
DESCRIPTION
An object of this class represents a handle to an R-related file. This class cannot be directly instantiated (it will die if you call "new" on it), because it is intended as a base abstract class with concrete subclasses to parse specific types of files, such as RDS or RData.
METHODS
CONSTRUCTOR new $filename The single-argument constructor can be invoked with a scalar containing the name of the R file. This file will be immediately opened for reading using IO::File. The method will raise an exception if the file is not readable. new ATTRIBUTE_HASH_OR_HASH_REF The constructor's arguments can also be given as a hash or hash reference, specifying values of the object attributes (in this case, 'fh', for which any subclass of IO::Handle can be used). ACCESSORS fh A file handle (stored as a reference to the IO::Handle) to the data being parsed. METHODS read Reads the contents of the filehandle and returns a Statistics::R::REXP. close Closes the object's filehandle. This method is automatically invoked when the object is destroyed.
BUGS AND LIMITATIONS
Instances of this class 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.
