Method Summary

Modifier and Type	Method	Description
static byte[]	generateProxyClass(java.lang.String proxyName, java.lang.Class<?> facade)	Generates a dynamic Provider-based proxy that reflects the given facade.
private static java.lang.String[]	getInternalNames(java.lang.Class<?>... clazzes)	Returns the internal names of the given classes.
private static java.util.Collection<java.lang.reflect.Method>	getWrappableMethods(java.lang.Class<?> clazz)	Returns the methods that should be wrapped for delegation in the given class.
private static void	init(ClassWriter cw, java.lang.String superName, java.lang.String proxyName)	Generates a constructor that accepts a Provider and stores it in an internal field.
private static boolean	isWrappable(java.lang.reflect.Method method)	Returns true if the given method should be wrapped; otherwise false.
private static java.lang.String	signatureKey(java.lang.reflect.Method method)	Returns a signature-based key that identifies the given method in the current class.
private static void	wrap(ClassWriter cw, java.lang.String proxyName, java.lang.reflect.Method method)	Generates a wrapper that dereferences the stored Provider and invokes the given method.

Method Detail

generateProxyClass

public static byte[] generateProxyClass(java.lang.String proxyName,
                                        java.lang.Class<?> facade)

Generates a dynamic Provider-based proxy that reflects the given facade.

Parameters:

proxyName - The proxy name

facade - The expected facade

Returns:

Generated proxy bytes

init

private static void init(ClassWriter cw,
                         java.lang.String superName,
                         java.lang.String proxyName)

Generates a constructor that accepts a Provider and stores it in an internal field.

wrap

private static void wrap(ClassWriter cw,
                         java.lang.String proxyName,
                         java.lang.reflect.Method method)

Generates a wrapper that dereferences the stored Provider and invokes the given method.

getInternalNames

private static java.lang.String[] getInternalNames(java.lang.Class<?>... clazzes)

Returns the internal names of the given classes.

getWrappableMethods

private static java.util.Collection<java.lang.reflect.Method> getWrappableMethods(java.lang.Class<?> clazz)

Returns the methods that should be wrapped for delegation in the given class.

isWrappable

private static boolean isWrappable(java.lang.reflect.Method method)

Returns true if the given method should be wrapped; otherwise false.

signatureKey

private static java.lang.String signatureKey(java.lang.reflect.Method method)

Returns a signature-based key that identifies the given method in the current class.
