public class JoinPointFactory
extends Object

TODO is factory a good name, now that it does so much more?

Factory for the different join point implementations. Compiles a new join point on the fly and loads the class.

Method Detail

compileJoinPointAndAttachToClassLoader

public static Class compileJoinPointAndAttachToClassLoader(CompilationInfo.Model model,
                                                           ClassLoader loader)

Compiles and loades a join point class, one specific class for each distinct join point.

Parameters:

model - the model for the compilation

loader - the class loader that the compiled join point should live in

Returns:

the compiled join point class

attachToClassLoader

public static Class attachToClassLoader(String joinpointClassName,
                                        ClassLoader loader,
                                        byte[] bytecode)

Loads a join point class, one specific class for each distinct join point.

Parameters:

joinpointClassName -

loader - the class loader that the compiled join point should live in

bytecode - of the joinpoint

Returns:

the compiled join point class

addCompilationInfo

public static void addCompilationInfo(Class clazz,
                                      CompilationInfo compilationInfo)

Adds or updates a compilation info. The class key is always the first compiled join point class.

Parameters:

clazz -

compilationInfo -

compileJoinPoint

public static byte[] compileJoinPoint(CompilationInfo.Model model)

Compiles a join point class, one specific class for each distinct join point.

Parameters:

model - the model for the compilation

Returns:

the compiled join point bytecode

redefineJoinPoint

public static byte[] redefineJoinPoint(CompilationInfo compilationInfo)

Redefines the originally compiled join point.

Parameters:

compilationInfo - the model for the compilation

Returns:

the compiled join point bytecode

getJoinPointsMatching

public static Set getJoinPointsMatching(ExpressionInfo expression)

Returns a list with all the join point compilers that matches a specific pointcut expression.

To be used for redefinition of the join point compilers only. This since the compilers must have been created in advance to exist in the repository (which is done when the target class is loaded).

Parameters:

expression - the pointcut expression

Returns:

a set with the matching emitted join point

getEmittedJoinPoint

public static EmittedJoinPoint getEmittedJoinPoint(Class clazz)

Returns the emitted join point structure for a specific JIT generated join point class.

Parameters:

clazz - the join point class

Returns:

the emitted join point structure
