Error handling

Unless otherwise explicitly 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.

info

A hash reference of metadata saved with this file.

print

    $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.

slurp

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

Return the number of bytes specified from the offset specified. If no $length or $offset are given, the entire file is returned.
