Hi,

I am trying to Boost::for_each function to set a local variable if all elements in this is DEFAULT type.

Here is my code, but I don't know how to implement the last part of the if_then call.

boolean rtnValue = false;

bool rtnValue = true; // assume true

...

for_each(mylist.begin(), mylist.end(), if_then( bind(&ListItem::getType, _1) == DEFAULT, set the local value to true if true if all of them are DEFAULT type ));

bind(&ListItem::getType, _1) != DEFAULT, set the local value to false));

bool rtnValue = find_if( mylist.begin(), mylist.end(), bind(&ListItem::getType, _1) != DEFAULT ) == mylist.end();
