class
ClosureMirror

A ClosureMirror reflects a closure.

A ClosureMirror provides the ability to execute its reflectee and introspect its function.

Implements

Properties

MethodMirror function
read-only
A mirror on the function associated with this closure.
bool hasReflectee
read-only , inherited
Does [reflectee] contain the instance reflected by this mirror? This will always be true in the local case (reflecting instances in the same isolate), but only true in the remote case if this mirror reflects a simple value.
dynamic reflectee
read-only , inherited
If the [InstanceMirror] reflects an instance it is meaningful to have a local reference to, we provide access to the actual instance here.
ClassMirror type
read-only , inherited
A mirror on the type of the reflectee.

Methods

apply(List positionalArguments, [Map<Symbol> namedArguments]) → InstanceMirror
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.
setField(Symbol fieldName, Object value) → InstanceMirror
inherited
Invokes a setter and returns a mirror on the result. The setter may be either the implicit setter for a non-final field or a user-defined setter method.
delegate(Invocation invocation) → dynamic
inherited
Perform invocation on reflectee. Equivalent to
getField(Symbol fieldName) → InstanceMirror
inherited
Invokes a getter and returns a mirror on the result. The getter can be the implicit getter for a field or a user-defined getter method.
invoke(Symbol memberName, List positionalArguments, [Map<Symbol> namedArguments]) → InstanceMirror
inherited
Invokes the named function and returns a mirror on the result.
