NetSDS::EDR - read/write Event Details Records
=head1 SYNOPSIS
use NetSDS::EDR;
my $edr = NetSDS::EDR->new(
filename => '/mnt/billing/call-stats.dat',
);
...
$edr->write(
{
callerid => '80441234567',
clip => '89001234567',
start_time => '2006-12-55 12:21:46',
end_time => '2008-12-55 12:33:22'
}
);
=head1 DESCRIPTION
C<NetSDS::EDR> module implements API for writing EDR (Event Details Record) files
form applications.
EDR itself is set of structured data describing details of some event. Exact
structure depends on event type and so hasn't fixed structure.
In NetSDS EDR data is written to plain text files as JSON structures one row per record.

=head1 CLASS API
=over
=item B<new(%params)> - class constructor
Parameters:
* filename - EDR file name
Example:
my $edr = NetSDS::EDR->new(
filename => '/mnt/stat/ivr.dat',
);
=cut
#-----------------------------------------------------------------------
sub new {
my ( $class, %params ) = @_;
my $self = $class->SUPER::new(%params);
# Create JSON encoder for EDR data processing
$self->{encoder} = JSON->new();
# Initialize file to write
if ( $params{filename} ) {
$self->{edr_file} = $params{filename};
} else {
return $class->error("Absent mandatory parameter 'filename'");
}
return $self;
}
#***********************************************************************
=item B<write($rec1 [,$rec2 [...,$recN]])> - write EDR to file
This methods converts records to JSON and write to file.
Each record writing to one separate string.
Example:
$edr->write({from => '380441234567', to => '5552222', status => 'busy'});
=cut
#-----------------------------------------------------------------------
sub write {
my ( $self, @records ) = @_;
open EDRF, ">>$self->{edr_file}";
# Write records - one record per line
foreach my $rec (@records) {
my $edr_json = $self->{encoder}->encode($rec);
print EDRF "$edr_json\n";
}
close EDRF;
}
