ComposedFunction

Compose two Functions.

class ComposedFunction(A, B, C, D)
class ComposedFunction : Function!(A, D)(
A
B
C
D
) if (
is(B : C)
) {
Function!(A, B) f;
Function!(C, D) g;
this(Function!(A, B) f, Function!(C, D) g);
D opCall(A x);
}
auto compose(F f, G g)

Constructors

this this(Function!(A, B) f, Function!(C, D) g): Undocumented in source.

Functions

opCall D opCall(A x): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

f Function!(A, B) f;: Undocumented in source.
g Function!(C, D) g;: Undocumented in source.

Examples

auto f = RealFunction!(triple!int).get.compose(RealFunction!(increment!int).get);
auto g = RealFunction!(increment!int).get.compose(RealFunction!(triple!int).get);
assert (f(0) == 1);
assert (f(1) == 4);
assert (g(0) == 3);
assert (g(1) == 6);
