Function rt.aApply._aApplycd1
Loop over a string while changing the UTF encoding
extern(C) int _aApplycd1
(
scope const(char)[] aa,
int delegate(void*) dg
);
There are 6 combinations of conversions between char
, wchar
, and dchar
,
and 2 of each of those.
The naming convention is as follows:
aApply{c,d,w}{c,d,w}{1,2}
The first letter corresponds to the input string encoding, and the second letter corresponds to the target character type.
- c = char
- w = wchar
- d = dchar
The 1
variant only produces the character, the 2
variant also produces a loop index.
Examples
void main()
{
string str;
wtring wstr;
dstring dstr;
foreach (dchar c; str) {}
// _aApplycd1
foreach (wchar c; dstr) {}
// _aApplydw1
foreach (i, wchar c; str) {}
// _aApplycw2
foreach (wchar w; wstr) {}
// no conversion
}
Parameters
Name | Description |
---|---|
aa | input string |
dg | foreach body transformed into a delegate, similar to opApply |
Returns
non-zero when the loop was exited through a break
