Net::SFTP::Buffer.3pm

NAME

Net::SFTP::Buffer - Read/write buffer class

SYNOPSIS

     use Net::SFTP::Buffer;
     my $buffer = Net::SFTP::Buffer->new;
 
 

DESCRIPTION

Net::SFTP::Buffer inherits from Net::SSH::Perl::Buffer to provide read/write buffer functionality for SSH. SFTP buffers are exactly the same as SSH buffers, with a couple of additions:

*

64-bit integers

SFTP requires the use of 64-bit integers to represent very large file sizes. In Net::SFTP::Buffer 64-bit integers are implemented as Math::Pari objects.

*

File attribute bundles

Attribute bundles are not strictly a simple data type---they are, in fact, made up of smaller pieces, like 32-bit integers, 64-bit integers, etc.--but for matters of convenience, it is easiest to provide methods to directly serialize/deserialize attributes from buffers.

USAGE

Usage of Net::SFTP::Buffer objects is exactly the same as usage of Net::SSH::Perl::Buffer objects, with additions of the following methods to support the above data types.

$buffer->get_int64

Extracts a 64-bit integer from $buffer and returns it as a Math::Pari object.

$buffer->put_int64($int)

Serializes a 64-bit integer $int into the buffer $buffer; $int can be either a Math::Pari object or a built-in Perl integer, if it is small enough to fit into a Perl int.

$buffer->get_attributes

Uses Net::SFTP::Attributes to extract a list of file attributes from $buffer, and returns a Net::SFTP::Attributes object containing those file attributes.

$buffer->put_attributes($attrs)

Serializes a Net::SFTP::Attributes object $attrs into the buffer $buffer.
