Rex::FS::File - File Class
This is the File Class used by file_write and file_read.
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;
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
Rex::Interface::File::*
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
Rex::FS::File
# 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.

Write $buf into the filehandle.
