rt.aApply

alias dg_t = int delegate(void* c);

Delegate type corresponding to transformed loop body

The parameter is a pointer to the current char, wchar or dchar

Returns:

non-zero when a break statement is hit

int _aApplycd1(in char[] aa, dg_t dg);

int _aApplywd1(in wchar[] aa, dg_t dg);

int _aApplycw1(in char[] aa, dg_t dg);

int _aApplywc1(in wchar[] aa, dg_t dg);

int _aApplydc1(in dchar[] aa, dg_t dg);

int _aApplydw1(in dchar[] aa, dg_t dg);

Loop over a string while changing the UTF encoding

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:

char[] aa	input string
dg_t dg	foreach body transformed into a delegate, similar to opApply

Returns:

non-zero when the loop was exited through a break

alias dg2_t = int delegate(void* i, void* c);

Delegate type corresponding to transformed loop body

Parameters are pointers to a size_t loop index, and the current char, wchar or dchar.

Returns:

non-zero when a break statement is hit

int _aApplycd2(in char[] aa, dg2_t dg);

int _aApplywd2(in wchar[] aa, dg2_t dg);

int _aApplycw2(in char[] aa, dg2_t dg);

int _aApplywc2(in wchar[] aa, dg2_t dg);

int _aApplydc2(in dchar[] aa, dg2_t dg);

int _aApplydw2(in dchar[] aa, dg2_t dg);

Variants of aApplyXXX that include a loop index.
