staticIsSorted

Checks if an AliasSeq is sorted according to cmp.

template staticIsSorted (

alias cmp

Seq...

) {

static if(Seq.length <= 1)

enum staticIsSorted;

static if(!(Seq.length <= 1))

static if(Seq.length == 2)

enum staticIsSorted;

static if(!(Seq.length <= 1))

static if(!(Seq.length == 2))

enum staticIsSorted;

}

Parameters

cmp: A template that returns a bool (if its first argument is less than the second one) or an int (-1 means less than, 0 means equal, 1 means greater than)
Seq: The AliasSeq to check

Return Value

true if Seq is sorted; otherwise false

Examples

enum Comp(int N1, int N2) = N1 < N2;
static assert( staticIsSorted!(Comp, 2, 2));
static assert( staticIsSorted!(Comp, 2, 3, 7, 23));
static assert(!staticIsSorted!(Comp, 7, 2, 3, 23));

enum Comp(T1, T2) = __traits(isUnsigned, T2) - __traits(isUnsigned, T1);
static assert( staticIsSorted!(Comp, uint, ubyte, ulong, short, long));
static assert(!staticIsSorted!(Comp, uint, short, ubyte, long, ulong));
