Class TypeToken<T>

java.lang.Object
name.martingeisse.grumpyjson.TypeToken<T>
Type Parameters:
T - the type to represent
public abstract class TypeToken<T> extends Object
This class is an easier way to represent a (parameterized) type than Type. It solves the following problem: To request deserialization of a type like List<String> from the JSON engine, that type must be specified. A class object cannot include type arguments, so won't do, and a Type would work but is cumbersome to get. This class solves the problem like so:

new TypeToken<List<String>>() {}

The type to represent is given as a type argument to this class. It is important to create an anonymous subclass -- hence the curly braces -- because that carries the type information from compile-time to run-time.

This class does not support any other features than getting the Type, such as equals/hashCode or type analysis.
