How to inject Predicate and Func in Spring.net

Question

I want to create an object with a constructor containing predicate and func objects in the xml config using spring. The Predicate and the Func arguments should point to a method of another configured object. How is this possible using Spring.net? I was not able to find a solution or hint in the documentation...

A sample constructor would be:

MyClass(Predicate<TInput> condition, Func<TInput, TOutput> result)

Answer 1

It is also possible to use the DelegateFactoryObject within Spring.net to create delegates (Action, Func, Predicate are only special delegates):

  <object type="Spring.Objects.Factory.Config.DelegateFactoryObject, Spring.Core">
    <property name="DelegateType" value="System.Action"/>
    <property name="TargetObject" ref="MyTarget" />
    <property name="MethodName" value="MyDelegate" />
  </object>

So you're not forced to create a construct such the MySpringConfigurationDelegateObjectContainer mentioned above to forward the delegates through factory methods anymore.
