  jodd.asm.EmptyMethodVisitor
      jodd.proxetta.asm.ProxettaMethodBuilder

All Implemented Interfaces:

org.objectweb.asm.MethodVisitor

public class ProxettaMethodBuilder
extends EmptyMethodVisitor

Field Summary

protected java.util.List<jodd.proxetta.asm.ProxyAspectData>	aspectList
protected MethodSignatureVisitor	msign
protected org.objectweb.asm.MethodVisitor	mv
static java.lang.String	TARGET_CLASS_NAME
protected jodd.proxetta.asm.TargetMethodData	tmd
protected jodd.proxetta.asm.WorkData	wd

Constructor Summary

ProxettaMethodBuilder(MethodSignatureVisitor msign, jodd.proxetta.asm.WorkData wd, java.util.List<jodd.proxetta.asm.ProxyAspectData> aspectList)

Method Summary

protected void	createFirstChainDelegate_Continue(jodd.proxetta.asm.TargetMethodData td) Continues the creation of the very first method in calling chain that simply delegates invocation to the first proxy method.
protected void	createFirstChainDelegate_Start() Starts creation of first chain delegate.
void	createProxyMethod(jodd.proxetta.asm.TargetMethodData td) Creates proxy methods over target method, For each matched proxy, new proxy method is created by taking advice bytecode and replaces usages of ProxyTarget.
org.objectweb.asm.AnnotationVisitor	visitAnnotation(java.lang.String desc, boolean visible) Copies target method annotations
org.objectweb.asm.AnnotationVisitor	visitAnnotationDefault() Visits the default value of this annotation interface method.
void	visitEnd() Finally, builds proxy methods if applied to current method.
org.objectweb.asm.AnnotationVisitor	visitParameterAnnotation(int parameter, java.lang.String desc, boolean visible) Visits an annotation of a parameter this method.

Constructor Detail

ProxettaMethodBuilder

public ProxettaMethodBuilder(MethodSignatureVisitor msign,
                             jodd.proxetta.asm.WorkData wd,
                             java.util.List<jodd.proxetta.asm.ProxyAspectData> aspectList)

Method Detail

visitAnnotation

public org.objectweb.asm.AnnotationVisitor visitAnnotation(java.lang.String desc,
                                                           boolean visible)

Copies target method annotations

Specified by:

visitAnnotation in interface org.objectweb.asm.MethodVisitor

Overrides:

visitAnnotation in class EmptyMethodVisitor

Parameters:

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitAnnotationDefault

public org.objectweb.asm.AnnotationVisitor visitAnnotationDefault()

Description copied from class: EmptyMethodVisitor

Visits the default value of this annotation interface method.

Specified by:

visitAnnotationDefault in interface org.objectweb.asm.MethodVisitor

Overrides:

visitAnnotationDefault in class EmptyMethodVisitor

Returns:

a visitor to the visit the actual default value of this annotation interface method, or null if this visitor is not interested in visiting this default value. The 'name' parameters passed to the methods of this annotation visitor are ignored. Moreover, exacly one visit method must be called on this annotation visitor, followed by visitEnd.

visitParameterAnnotation

public org.objectweb.asm.AnnotationVisitor visitParameterAnnotation(int parameter,
                                                                    java.lang.String desc,
                                                                    boolean visible)

Description copied from class: EmptyMethodVisitor

Visits an annotation of a parameter this method.

Specified by:

visitParameterAnnotation in interface org.objectweb.asm.MethodVisitor

Overrides:

visitParameterAnnotation in class EmptyMethodVisitor

Parameters:

parameter - the parameter index.

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitEnd

public void visitEnd()

Finally, builds proxy methods if applied to current method.

Specified by:

visitEnd in interface org.objectweb.asm.MethodVisitor

Overrides:

visitEnd in class EmptyMethodVisitor

createFirstChainDelegate_Start

protected void createFirstChainDelegate_Start()

Starts creation of first chain delegate.

createFirstChainDelegate_Continue

protected void createFirstChainDelegate_Continue(jodd.proxetta.asm.TargetMethodData td)

Continues the creation of the very first method in calling chain that simply delegates invocation to the first proxy method. This method mirrors the target method.

createProxyMethod

public void createProxyMethod(jodd.proxetta.asm.TargetMethodData td)

Creates proxy methods over target method, For each matched proxy, new proxy method is created by taking advice bytecode and replaces usages of ProxyTarget.

Invocation chain example: name -> name$p0 -> name$p1 -> name$p4 -> super
