MongoDB::GridFS::File - A Mongo GridFS file
version v0.999.999.1
use MongoDB::GridFS::File; $outfile = IO::File->new("outfile", "w"); $file = $grid->find_one; $file->print($outfile);
Unless otherwise explictly documented, all methods throw exceptions if an error occurs. The error types are documented in MongoDB::Error.
To catch and handle errors, the Try::Tiny and Safe::Isa modules are recommended:
use Try::Tiny; use Safe::Isa; # provides $_isa $bytes = try { $file->slurp; } catch { if ( $_->$_isa("MongoDB::TimeoutError" ) { ... } else { ... } };
To retry failures automatically, consider using Try::Tiny::Retry.
A hash reference of metadata saved with this file.
$written = $file->print($fh); $written = $file->print($fh, $length); $written = $file->print($fh, $length, $offset)
Writes the number of bytes specified from the offset specified to the given file handle. If no $length or $offset are given, the entire file is written to $fh. Returns the number of bytes written.

$all = $file->slurp $bytes = $file->slurp($length); $bytes = $file->slurp($length, $offset);
