Net_MAC::__construct (
object $db
, array $options
)
This is the constructor that will create and populate a valid Net_MAC object.
object $db - This parameter must
be a valid MDB2
object.
array $options - An array
of options to use with the database in retrieving MAC address
vendors. The associative array should have key/value
pairs as follows:
| Option | Description |
|---|---|
| tablename | The name of the table where MAC address vendor information lives |
| macaddrcol | The name of the column containing the MAC address prefixes |
| vendorcol | The name of the column containing the vendor name |
| desccol | The name of the column containing any extra descriptive information derived from the vendor list |
void - No return value. A Net_MAC_Exception Exception object will be thrown if there is an error during construction
The constructor can throw exceptions on error, so the constructor should always be called from inside a try/catch block.
