==============
|
|
|
|
This module contains the base class for a network element.
|
|
|
|
Strictly, a network element is any callable which accepts an immutable
|
|
.info.SpectralInformation object and returns a .info.SpectralInformation object
|
|
(a copy.)
|
|
|
|
Network elements MUST implement two attributes .uid and .name representing a
|
|
unique identifier and a printable name.
|
|
|
|
This base class provides a mode convenient way to define a network element
|
|
via subclassing.
