staticFilter

Performs filtering of expression tuple T one by one by function or template F. If F returns true the resulted element goes to returned expression tuple, else it is discarded.

template staticFilter (

alias F

T...

) {

alias staticFilter = ExpressionList!();

static if(!(T.length == 0))

static if(__traits(compiles, F(T[0])))

enum result;

static if(!(T.length == 0))

static if(!(__traits(compiles, F(T[0]))))

enum result;

alias staticFilter = ExpressionList!(T[0], staticFilter!(F, T[1..$]));

alias staticFilter = ExpressionList!(staticFilter!(F, T[1..$]));
