Detailed Description

template<typename Enum>
class ecl::Flags< Enum >

Convenience class for organising boolean flags.

This class organises a group of flags (via enums) in a convenient and typesafe manner. It is essentially a container for flags (in the form of enums) with a convenient interface on top.

Usage:

Define an appropriate bit-arithmetic enum.

enum Settings {
    Fast   0x0001,
    Medium 0x0002,
    Slow   0x0004,
    Red    0x0010,
    Blue   0x0020
}

Pipe flags into the enum

settings = settings|Fast|Slow;

Set up a friend operator on the enum type for more convenient piping (see the dox).
Use one of the variety of mask/compliment/access operators for handling (see method documentation).
