    +Useful for storing a vector of values using only a few number of bits for each +value. Apart from the standard operations of a vector-like container, it can +also perform an 'or' set operation. +

    + +

    For example:

    + +
    +
    +enum State {
+    None = 0x0,
+    FirstCondition = 0x1,
+    SecondCondition = 0x2,

+
+    PackedVector<State, 2> Vec2;
+    Vec2.push_back(SecondCondition);
+
+    Vec1 |= Vec2;
+    return Vec1[0]; // returns 'Both'.
+}
