tcpdump like implementation, writer mode

## NAME

Net::Frame::Dump::Writer - tcpdump like implementation, writer mode

## SYNOPSIS

```
   use Net::Frame::Dump::Writer;
   my $oDump = Net::Frame::Dump::Writer->new(
      file       => 'new-file.pcap',
      firstLayer => 'ETH',
   );
   $oDump->start;
   $oDump->write({ timestamp => '10.10', raw => ('A' x 14) });
   $oDump->stop;
```

## DESCRIPTION

This module implements a pcap file builder. You will be able to create frames, then write them in the pcap file format to a file.

## ATTRIBUTES

The following are inherited attributes:

- **file**

  Name of the .pcap file to generate.

- **overwrite**

  Overwrites a .pcap file that already exists. Default to not.

- **append**

  Append new frames to an existing pcap file. Create it if does not exists yet.

- **firstLayer**

  Stores information about the first layer type. It is used to write .pcap file header information.

- **isRunning**

  Returns true if a call to **start** has been done, false otherwise or if a call to **stop** has been done.

## METHODS

- **new**

  - **new** (hash)

  Object constructor. You can pass attributes that will overwrite default ones. See **SYNOPSIS** for default values.

- **start**

  When you want to start writing frames to the file, call this method.

- **stop**

  When you want to stop writing frames to the file, call this method.

- **write** ({ timestamp =\> $value, raw =\> $rawFrame })

  Takes a hashref as a parameter. This hashref MUST have timestamp and raw keys, with values. The raw data will be stored to the .pcap file.
