Method Detail

checkTypes

protected static void checkTypes(EvalNode node,
                                 int index,
                                 List<HistoneType> expectedTypes,
                                 List<Class<?>> classes)

Method validates argument EvalNode on int position with specified HistoneType and Class. If validation will failed, method returns error message. Otherwise method returns null.

Parameters:

node - eval node, which wrapping argument value

index - index in arguments list

expectedTypes - expected types of node

classes - expected types of node wrapped value
