percentage complete iterating modelspace entities
percentage complete iterating modelspace entities
i am iterating the modelspace entities using a iterator. so my for loop uses the sual:
piter->start() ; !piter->done(); piter->step()
but in order to establish the percentage complete through the iteration process, i need to know how many iterating steps there are.
at the moment, i can't work out how to ascertain the percentage complete i am iterating through the modelspace entities.
this was possible in legacy toolkit because you knew the total number of entities.
please assist me. i expect i am miss reading a function that clearly does what i need.
thanks.

currently there is no other method of getting number of entities in block except using iterator to count them.
sergey slezkin
is there going to be?
i am concerned at the way it will slow app down to read them twice.
but i can do it for now if that is the only way.
andrew
currently entities in block table record are stored as a list and method like numentities() will perform the same iteration.
untill dd internals are redesigned to store entities in some other manner it's better for client to know that counting entities is an expensive operation. now i can't say when this will be changed.

numentries seems to only be applicable to these classes:
oddbauditinfo
oddbgroup
oddbselectionset
none of these seem to be applicable to the oddbblocktable class.

i mean that we have not introduced numentities() method in blockrecord class because ......
btw objectarx have no such method too.
sergey slezkin
oh.
so i must iterate them first.
