For example, given a factory method with the following signature, if `resolveReturnTypeForFactoryMethod()` is invoked with the reflected method for `createProxy()` and an `Object[]` array containing `MyService.class`, `resolveReturnTypeForFactoryMethod()` will infer that the target return type is `MyService`. `public static <T> T createProxy(Class<T> clazz)` Possible Return Values the target return type, if it can be inferred the standard return type, if the given `method` does not declare any formal type variables the standard return type, if the target return type cannot be inferred (e.g., due to type erasure) `null`, if the length of the given arguments array is shorter than the length of the formal argument list for the given method Parameters method:Method the method to introspect (never `null`) args:Object[] the arguments that will be supplied to the method when it is invoked (never `null`) classLoader:ClassLoader the ClassLoader to resolve class names against, if necessary (never `null`) Returns:Class<?> the resolved target return type or the standard method return type Since 3.2.5

public static Class<?> resolveReturnTypeForFactoryMethod(Method method, Object[] args, ClassLoader classLoader)

Determine the target type for the generic return type of the given generic factory method, where formal type variables are declared on the given method itself.

For example, given a factory method with the following signature, if resolveReturnTypeForFactoryMethod() is invoked with the reflected method for createProxy() and an Object[] array containing MyService.class, resolveReturnTypeForFactoryMethod() will infer that the target return type is MyService.

public static <T> T createProxy(Class<T> clazz)

Possible Return Values

the target return type, if it can be inferred
the standard return type, if the given method does not declare any formal type variables
the standard return type, if the target return type cannot be inferred (e.g., due to type erasure)
null, if the length of the given arguments array is shorter than the length of the formal argument list for the given method

Parameters

method:Method: the method to introspect (never null)
args:Object[]: the arguments that will be supplied to the method when it is invoked (never null)
classLoader:ClassLoader: the ClassLoader to resolve class names against, if necessary (never null)

Returns:Class<?>

the resolved target return type or the standard method return type

public Object invoke(Object proxy, Method method, Object[] args) throws Throwable Implements java.lang.reflect.InvocationHandler.invoke. Doc from java.lang.reflect.InvocationHandler.invoke. Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with. Parameters proxy:Object the proxy instance that the method was invoked on method:Method the `Method` instance corresponding to the interface method invoked on the proxy instance. The declaring class of the `Method` object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through. args:Object[] an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or `null` if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as `java.lang.Integer` or `java.lang.Boolean`. Returns:Object the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is `null` and the interface method's return type is primitive, then a `NullPointerException` will be thrown by the method invocation on the proxy instance. If the value returned by this method is otherwise not compatible with the interface method's declared return type as described above, a `ClassCastException` will be thrown by the method invocation on the proxy instance. Annotations @Override Exceptions Throwable: the exception to throw from the method invocation on the proxy instance. The exception's type must be assignable either to any of the exception types declared in the `throws` clause of the interface method or to the unchecked exception types `java.lang.RuntimeException` or `java.lang.Error`. If a checked exception is thrown by this method that is not assignable to any of the exception types declared in the `throws` clause of the interface method, then an `UndeclaredThrowableException` containing the exception that was thrown by this method will be thrown by the method invocation on the proxy instance.

public Object invoke(Object proxy, Method method, Object[] args) throws Throwable

Implements java.lang.reflect.InvocationHandler.invoke.

Doc from java.lang.reflect.InvocationHandler.invoke.

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Parameters

proxy:Object: the proxy instance that the method was invoked on
method:Method: the Method instance corresponding to the interface method invoked on the proxy instance. The declaring class of the Method object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through.
args:Object[]: an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.

Returns:Object

the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is null and the interface method's return type is primitive, then a NullPointerException will be thrown by the method invocation on the proxy instance. If the value returned by this method is otherwise not compatible with the interface method's declared return type as described above, a ClassCastException will be thrown by the method invocation on the proxy instance.

Exceptions

Throwable:: the exception to throw from the method invocation on the proxy instance. The exception's type must be assignable either to any of the exception types declared in the throws clause of the interface method or to the unchecked exception types java.lang.RuntimeException or java.lang.Error. If a checked exception is thrown by this method that is not assignable to any of the exception types declared in the throws clause of the interface method, then an UndeclaredThrowableException containing the exception that was thrown by this method will be thrown by the method invocation on the proxy instance.
