Class ValueType<T>

java.lang.Object
cc.carm.lib.configuration.adapter.ValueType<T>
public abstract class ValueType<T> extends Object
ValueType used to get the generic type of the value, It can be used to check if an object is an instance of a specific type, and to cast objects to the correct type.

Java's type system is not capable of retaining generic type information at runtime. This class is used to represent a type with its generic parameters.
