public abstract voidassertInstanceOfLocalInterfaceImpl(java.lang.Object o)
Validates that this instance is of the correct implementation class of a local interface type.

param
o the instance to validate.
return
true if the type is correct.
throws
IllegalArgumentException if validation fails.

protected voidassertInstanceOfLocalInterfaceImpl(java.lang.Object o, java.lang.String beanName)
Validates that this instance is of the correct implementation class
of a local interface.
Throws IllegalArgumentException if the passed
argument is of a wrong type.
