Method Detail

assertClass

public void assertClass(java.lang.String methodName,
                        java.lang.String argName,
                        java.lang.Class<?> cl,
                        java.lang.Object obj)

Utility method for detailed problem reporting when an object that gets passed to a policy method does not have the correct type. Policies intentionally do not use Generics as their usage would have increased the policy complexity too much.

Parameters:

methodName - the method that wants to assert / make sure that the given object does have the correct type

argName - the name of the method argument that requires a certain object type

cl - the required object type

obj - the object that got passed to the method and that gets checked for whether it has the right type or not
