Method Detail

getGeneratorAdapter

public org.objectweb.asm.commons.GeneratorAdapter getGeneratorAdapter()

loadInvocationHandlerFromProxy

public MethodBuilder loadInvocationHandlerFromProxy()

Loads the AgentWrapper onto the stack by getting it from AgentBridge.agentHandler

invokeInvocationHandlerInterface

public MethodBuilder invokeInvocationHandlerInterface(boolean popTheReturnValue)

Invokes InvocationHandler.invoke(Object, java.lang.reflect.Method, Object[])

Parameters:

popTheReturnValue - if true, the return value of the invoke call will be popped off the stack

loadInvocationHandlerProxyAndMethod

public MethodBuilder loadInvocationHandlerProxyAndMethod(java.lang.Object value)

Loads the first two arguments to a InvocationHandler.invoke(Object, java.lang.reflect.Method, Object[]) call onto the stack. The given value is loaded as the first argument, and the second argument (Method) is always null.

loadArray

public MethodBuilder loadArray(java.lang.Class<?> arrayClass,
                               java.lang.Object... objects)

Creates an array containing the objects passed in. If one of the objects is a Runnable, Runnable.run() will we invoked to push a value onto the stack. There is built in support for Integers and Booleans. An array object may also be one of the special identifiers on this class like LOAD_THIS or LOAD_ARG_ARRAY.

Parameters:

arrayClass - Class of array to create.

objects -
