July 21, 2005 Howto call foreach for void[char[]] | ||||
---|---|---|---|---|
| ||||
Howto make this work:
void[char[]] mSupportedMechanisms;
foreach(char[] mech , void b; mSupportedMechanisms){
/* foo */
}
As you can see, I need a set. I thought "map is a set with pairs, so why not to make void[char[]]". But when comes to using foreach I couldn't find a way to get things working.

Use .keys:
foreach(char[] mech; mSupportedMechanisms.keys){
}
This presently involves an allocation, but the compiler should handle it better in the future. If you must avoid that, then you'll need to use non-void as the value.

Or use 'void[]' or 'void*' as the value.
