javax.ws.rs.core
Class GenericType<T>

java.lang.Object
  javax.ws.rs.core.GenericType<T>

Type Parameters:

T - the generic type parameter.

public class GenericType<T>
extends java.lang.Object

Represents a generic message entity type T. Supports in-line instantiation of objects that represent generic types with actual type parameters. An object that represents any parameterized type may be obtained by sub-classing GenericType. Alternatively, an object representing a concrete parameterized type can be created using a GenericType(java.lang.reflect.Type) and manually specifying the actual (parameterized) type.

  GenericType<List<String>> stringListType = new GenericType<List<String>>() {};

Constructor Detail

GenericType

protected GenericType()

Constructs a new generic type, deriving the generic type and class from type parameter. Note that this constructor is protected, users should create a (usually anonymous) subclass as shown above.

GenericType

public GenericType(java.lang.reflect.Type genericType)

Constructs a new generic type, supplying the generic type information and deriving the class.

Parameters:

genericType - the generic type.

Throws:

java.lang.IllegalArgumentException - if genericType is null or not an instance of Class or ParameterizedType whose raw type is an instance of Class.
