Invokes the named constructor and returns a mirror on the result.
Let c be the class reflected by this mirror
let a1, ..., an be the elements of positionalArguments
let k1, ..., km be the identifiers denoted by the elements of
namedArguments.keys
and let v1, ..., vm be the elements of namedArguments.values
.
If constructorName
was created from the empty string
Then this method will execute the instance creation expression
new c(a1, ..., an, k1: v1, ..., km: vm)
in a scope that has access to the private members
of c. Otherwise, let
f be the simple name of the constructor denoted by constructorName
Then this method will execute the instance creation expression
new c.f(a1, ..., an, k1: v1, ..., km: vm)
in a scope that has access to the private members
of c.
In either case:
If the expression evaluates to a result r, this method returns
the result of calling reflect\(r\).
If evaluating the expression causes a compilation error
the effect is the same as if a non-reflective compilation error
had been encountered.
If evaluating the expression throws an exception e
(that it does not catch)
this method throws e.
