| RangeSegmentTreeTraits_k::Key | |
|
The k-dimensional key type.
| |
| RangeSegmentTreeTraits_k::Interval | |
|
The k-dimensional interval type.
| |
| RangeSegmentTreeTraits_k::Key_i | |
|
The type in dimension i, with 1 ≤ i
≤ k.
| |
| RangeSegmentTreeTraits_k::key_i | |
|
function object providing an
operator() that takes an argument of type Key and returns
a component of type Key_i.
| |
| RangeSegmentTreeTraits_k::low_i | |
|
function object providing an
operator() that takes an argument of type Interval and returns
a component of type Key_i.
| |
| RangeSegmentTreeTraits_k::high_i | |
|
function object providing an
operator() that takes an argument of type Interval and returns
a component of type Key_i.
| |
| RangeSegmentTreeTraits_k::compare_i | |
|
function object providing an
operator() that takes two arguments argument a, b of type Key_i and returns
true if a<b, false otherwise.

The following piece of code gives an example of how a traits class might look like, if you have keys that are of the type int in the first and that are of the type double in the second dimension.
