Methods

Modifier and Type	Method and Description
protected static void	addArgumentFieldsAndAccessors(javassist.ClassPool pool, javassist.CtClass invocation, javassist.CtClass[] params, boolean hasMarshalledArguments) Adds typed argument fields to invocation and overwrites its arguments field accessor methods accordingly.
protected static void	addDispatch(javassist.CtClass invocation, String methodName, javassist.CtClass[] params, String dispatchLine, String beforeDispatch, String afterDispatch) Creates a method that dispatches execution to a joinpoint, and adds this method to invocation class.
protected static String	setArguments(int length) Returns a piece of code that sets all typed argument fields to the parameter values of current behaviour (i.e., arg0 = $1; arg1 = $2...).

ENFORCE_ARGS_CONSISTENCY

public static final String ENFORCE_ARGS_CONSISTENCY

Name of method that enforces consistency between the values contained in typed argument fields and those contained in arguments array. This method is added to all optimized invocations that contain arguments field.

Method Detail

setArguments

protected static String setArguments(int length)

Returns a piece of code that sets all typed argument fields to the parameter values of current behaviour (i.e., arg0 = $1; arg1 = $2...).

Parameters:

length - total number of parameters

Returns:

code that sets all argument fields to the values of current behaviour parameters

addArgumentFieldsAndAccessors

protected static void addArgumentFieldsAndAccessors(javassist.ClassPool pool,
                                 javassist.CtClass invocation,
                                 javassist.CtClass[] params,
                                 boolean hasMarshalledArguments)
                                             throws javassist.NotFoundException,
                                                    javassist.CannotCompileException

Adds typed argument fields to invocation and overwrites its arguments field accessor methods accordingly.

Parameters:

pool - class pool that contains invocation

invocation - invocation class to which fields and methods will be added

params - list of the parameter types

hasMarshalledArguments - indicates whether invocationhas a marshalled arguments field

Throws:

javassist.NotFoundException

javassist.CannotCompileException

addDispatch

protected static void addDispatch(javassist.CtClass invocation,
               String methodName,
               javassist.CtClass[] params,
               String dispatchLine,
               String beforeDispatch,
               String afterDispatch)
                           throws javassist.NotFoundException,
                                  javassist.CannotCompileException

Creates a method that dispatches execution to a joinpoint, and adds this method to invocation class.
Except for its name, the generated method is constrained to have the same signature as InvocationBase.invokeTarget().

Parameters:

invocation - optimized invocation class

methodName - name of the generated method

dispatchLine - line that dispatches the execution to joinpoint. This line must not cointain ';' nor brackets or the arguments list.

params - joinpoint parameters type

beforeDispatch - one or more lines of code that should be executed before dispatchLine (this code must be complete, without compilation errors)

afterDispatch - one or more lines of code that should be executed after dispatchLine (this code must be complete, without compilation errors)

Throws:

javassist.NotFoundException

javassist.CannotCompileException
