Alias std.traits.FunctionTypeOf
Get the function type from a callable object func
.
alias FunctionTypeOf(func...)
= Fsym;
Using builtin typeof
on a property function yields the types of the
property value, not of the property function itself. Still,
FunctionTypeOf
is able to obtain function types of properties.
Note
Do not confuse function types with function pointer types; function types are usually used for compile-time reflection purposes.
Example
class C
{
int value() @property { return 0; }
}
static assert(is( typeof(C .value) == int ));
static assert(is( FunctionTypeOf!(C .value) == function ));
