Examples of TypeToken

• cc.concurrent.mango.util.TypeToken

• com.google.common.reflect.TypeToken
  A {@link Type} with generics.

  Operations that are otherwise only available in {@link Class} are implemented to support{@code Type}, for example {@link #isAssignableFrom}, {@link #isArray} and {@link #getComponentType}. It also provides additional utilities such as {@link #getTypes} and {@link #resolveType} etc.

  There are three ways to get a {@code TypeToken} instance:

  • Wrap a {@code Type} obtained via reflection. For example: {@code TypeToken.of(method.getGenericReturnType())}.
  • Capture a generic type with a (usually anonymous) subclass. For example:

        {@code}new TypeToken>()  

    Note that it's critical that the actual type argument is carried by a subclass. The following code is wrong because it only captures the {@code } type variableof the {@code listType()} method signature; while {@code } is lost in erasure:

        {@code}class Util  static  TypeToken> listType() { return new TypeToken>() {}; } } TypeToken> stringListType = Util.listType();}

  • Capture a generic type with a (usually anonymous) subclass and resolve it against a context class that knows what the type parameters are. For example:

        {@code}abstract class IKnowMyType  TypeToken type = new TypeToken(getClass()) {}; } new IKnowMyType() {}.type => String}

  {@code TypeToken} is serializable when no type variable is contained in the type.

  Note to Guice users: {@code} TypeToken is similar to Guice's {@code TypeLiteral} classexcept that it is serializable and offers numerous additional utility methods. @author Bob Lee @author Sven Mawson @author Ben Yu @since 12.0

• com.google.gson.reflect.TypeToken
  Represents a generic type {@code T}. You can use this class to get the generic type for a class. For example, to get the generic type for Collection<Foo>, you can use:

  Type typeOfCollectionOfFoo = new TypeToken<Collection<Foo>>(){}.getType()

  Assumes {@code Type} implements {@code equals()} and {@code hashCode()}as a value (as opposed to identity) comparison. Also implements {@link #isAssignableFrom(Type)} to check type-safeassignability. @author Bob Lee @author Sven Mawson

• org.structr.common.error.TypeToken
