Constructor
Create a refrence to a byte stream that is going to be parsed or created
by the methods in the class. Detect if the class should use big or
little Endian encoding.
Parameters
Create a refrence to a byte stream that is going to be parsed or created
by the methods in the class. Detect if the class should use big or
little Endian encoding.
string $stream |
use '' if creating a new stream or pass a string if reading. |
