Thanks for your prompt reply ! The problem is I DO KNOW there will be never overlapping. ----- Mail original -----

Hello,
I declared an interval_map :
interval_map<uint16_t, SomeEnumType> myMap;
Later, I do :
SomeEnumType enumValue = SOME_ENUM_VALUE; myMap.add(std::make_pair(disxrete_interval<uint16_t>(10,17), SOME_ENUM_VALUE);
But that doesn't compile.
It seems that ICL wants the += operator must eb defined for value type (why ???).
What can I do ?
Hi,
If I remember correctly, you need to supply a combiner. The default combiner uses +=.
A combiner produces a new value for overlapping intervals. Consider (pseudocode):
myMap.add( [10,17), SOME_ENUM_VALUE ); myMap.add( [16,18), OTHER_ENUM_VALUE );
The combiner decides, what should be the value in [16,17). In this case, tries to += the OTHER_ENUM_VALUE to the existing SOME_ENUM_VALUE.
