NAME
FlatFile::DataStore::Record - Perl module that implements a flat file data store record class.
SYNOPSYS
# first, create a preamble object
use FlatFile::DataStore::Preamble;
my $preamble = FlatFile::DataStore::Preamble->new( {
datastore => $ds, # FlatFile::DataStore object
indicator => $indicator, # single-character crud flag
transind => $transind, # single-character crud flag
date => $date, # pre-formatted date
transnum => $transint, # transaction number (integer)
keynum => $keynum, # record sequence number (integer)
reclen => $reclen, # record length (integer)
thisfnum => $fnum, # file number (in base format)
thisseek => $datapos, # seek position (integer)
prevfnum => $prevfnum, # ditto these ...
prevseek => $prevseek,
nextfnum => $nextfnum,
nextseek => $nextseek,
user => $user_data, # pre-formatted user-defined data
} );
# then create a record object with the preamble contained in it
use FlatFile::DataStore::Record;
my $record = FlatFile::DataStore::Record->new( {
preamble => $preamble, # i.e., a preamble object
data => "This is a test record.", # actual record data
} );
DESCRIPTION
FlatFile::DataStore::Record is a Perl module that implements a flat file data store record class. This class defines objects used by FlatFile::DataStore. You will likely not ever call new() yourself, (FlatFile::DataStore::create() would, e.g., do that) but you will likely call the accessors.
VERSION
FlatFile::DataStore::Record version 1.00
CLASS METHODS
FlatFile::DataStore::Record->new( $parms )
Constructs a new FlatFile::DataStore::Record object.
The parm $parms
is a hash reference containing key/value pairs to populate the record string. Two keys are recognized:
- preamble, i.e., a FlatFile::DataStore::Preamble object
- data, the actual record data
The record data is stored in the object as a scalar reference, and new() will accept a scalar ref, e.g.,
my $record_data = "This is a test record.";
my $record = FlatFile::DataStore::Record->new( {
preamble => $preamble_obj,
data => \$record_data,
} );
OBJECT METHODS: Accessors
The following read/write methods set and return their respective attribute values if $value
is given. Otherwise, they just return the value.
$record->data( $value ); # actual record data as a scalar ref
$record->preamble( $value ); # FlatFile::DataStore::Preamble object
The following read-only methods just return their respective values. The values all come from the record's contained preamble object.
$record->user()
$record->preamble_string() # the 'string' attr of the preamble
$record->indicator()
$record->transind()
$record->date()
$record->transnum()
$record->keynum()
$record->reclen()
$record->thisfnum()
$record->thisseek()
$record->prevfnum()
$record->prevseek()
$record->nextfnum()
$record->nextseek()
$record->is_created()
$record->is_updated()
$record->is_deleted()
