# apply method

InstanceMirror apply (List positionalArguments, [ Map<Symbol, dynamic> namedArguments ])

Executes the closure and returns a mirror on the result.

Let f be the closure 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`.

Then this method will perform the method invocation f(a1, ..., an, k1: v1, ..., km: vm).

If the invocation returns a result r, this method returns the result of calling reflect(r).

If the invocation causes a compilation error, the effect is the same as if a non-reflective compilation error had been encountered.

If the invocation throws an exception e (that it does not catch), this method throws e.

## Implementation

    InstanceMirror apply(List positionalArguments,
        [Map<Symbol, dynamic> namedArguments]);
