NAME

Rex::FS::File - File Class

DESCRIPTION

This is the File Class used by file_write and file_read.

SYNOPSIS

use Rex::Interface::File;
my $fh = Rex::Interface::File->create('Local');
$fh->open( '<', 'filename' );

my $file = Rex::FS::File->new(fh => $fh);
$file->read($len);
$file->read_all;
$file->write($buf);
$file->close;

CLASS METHODS

new

This is the constructor. You need to set the filehandle which the object should work on or pass a filename. If you pass a filehandle, it has to be a Rex::Interface::File::* object

my $fh = Rex::Interface::File->create('Local');
$fh->open( '<', 'filename' );

my $file = Rex::FS::File->new(fh => $fh);

Create a Rex::FS::File object with a filename

# open a local file in read mode
my $file = Rex::FS::File->new(
  filename => 'filename',
  mode     => 'r', # or '<'
  type     => 'Local',
);

# or shorter
my $file = Rex::FS::File->new( filename => 'filename' );

# open a local file in write mode
my $file = Rex::FS::File->new(
  filename => 'filename',
  mode     => 'w', # or '>'
);

Allowed modes:

<  read
r  read
>  write
w  write
>> append
a  append

For allowed types see documentation of Rex::Interface::File.
