This read-only map assigns true
to the keys for which the corresponding value of the first map is less then the value of the second map. Its Key
type is inherited from M1
and its Value
type is bool
. M2::Key
must be convertible to M1::Key
.
If m1
is of type M1
and m2
is of M2
, then for
lm[x]
will be equal to m1[x]<m2[x]
.
The simplest way of using this map is through the lessMap() function.
