Interface Callbacks

All Known Implementing Classes:

SimpleCallbacks

public interface Callbacks

Provides a method to map from callback types (as defined per-method by a CallbackFilter) to a particular Callback implementation. The callback type constants are defined here as well. In practice it should be rare to need to implement this interface. See SimpleCallbacks for a simple implementation.

Field Summary

static int	DISPATCH Callback type used to load an implementation for every single method invocation.
static int	INTERCEPT Generic interceptor callback type.
static int	JDK_PROXY Special callback type used by the Proxy class for java.lang.reflect.Proxy compatibility.
static int	LAZY_LOAD Callback type used to load an implementation as soon as the first method is called, Callback implementation is LazyLoader.
static int	MAX_VALUE
static int	NO_OP No-op callback type.

Method Summary

Callback

get(int type) Return the actual Callback implementation for the specified callback type.

Field Detail

NO_OP

public static final int NO_OP

No-op callback type. Does not generate an intercepted method in the subclass--the "super" method will be called directly instead. No associated Callback implementation.

Constant Field Values

INTERCEPT

public static final int INTERCEPT

Generic interceptor callback type. Callback implementation is MethodInterceptor.

See Also:

MethodInterceptor, Constant Field Values

JDK_PROXY

public static final int JDK_PROXY

Special callback type used by the Proxy class for java.lang.reflect.Proxy compatibility. You probably don't want to use this directly. Callback implementation is InvocationHandler.

Proxy, InvocationHandler, Constant Field Values

LAZY_LOAD

public static final int LAZY_LOAD

Callback type used to load an implementation as soon as the first method is called, Callback implementation is LazyLoader.

See Also:

LazyLoader, Constant Field Values

DISPATCH

public static final int DISPATCH

Callback type used to load an implementation for every single method invocation. Callback implementation is Dispatcher.

See Also:

Dispatcher, Constant Field Values

MAX_VALUE

public static final int MAX_VALUE

Constant Field Values

Method Detail

get

public Callback get(int type)

Return the actual Callback implementation for the specified callback type.

Parameters:

type - the callback type

Returns:

the callback implementation
