Called to convert a Java object result of a DataFetcher to a valid runtime value for the scalar type.
Note : Throw CoercingSerializeException
if there is fundamental
problem during serialization, don't return null to indicate failure.
Note : You should not allow RuntimeException
s to come out of your serialize method, but rather
catch them and fire them as CoercingSerializeException
instead as per the method contract.

Many scalar types don't need to implement this method because they don't take AST VariableReference
objects and convert them into actual values. But for those scalar types that want to do this, then this
method should be implemented.
