Constructor Detail

ProxettaClassBuilder

public ProxettaClassBuilder(jodd.asm5.ClassVisitor dest,
                            ProxyAspect[] aspects,
                            java.lang.String suffix,

                            TargetClassInfoReader targetClassInfoReader)

Constructs new Proxetta class builder.

Parameters:

dest - destination visitor

aspects - set of aspects to apply

suffix - proxy class name suffix, may be null

reqProxyClassName - requested proxy class name, may be nulls

targetClassInfoReader - target info reader, already invoked.

Method Detail

getWorkData

public WorkData getWorkData()

Returns working data.

visit

public void visit(int version,
                  int access,
                  java.lang.String name,
                  java.lang.String signature,
                  java.lang.String superName,
                  java.lang.String[] interfaces)

Creates destination subclass header from current target class. Destination name is created from targets by adding a suffix and, optionally, a number. Destination extends the target.

Overrides:

visit in class jodd.asm5.ClassVisitor

visitMethod

public jodd.asm5.MethodVisitor visitMethod(int access,
                                           java.lang.String name,
                                           java.lang.String desc,
                                           java.lang.String signature,
                                           java.lang.String[] exceptions)

Creates proxified methods and constructors. Destination proxy will have all constructors as a target class, using ProxettaCtorBuilder. Static initializers are removed, since they will be execute in target anyway. For each method, ProxettaMethodBuilder determines if method matches pointcut. If so, method will be proxified.

Overrides:

visitMethod in class jodd.asm5.ClassVisitor

visitField

public jodd.asm5.FieldVisitor visitField(int access,
                                         java.lang.String name,
                                         java.lang.String desc,
                                         java.lang.String signature,
                                         java.lang.Object value)

Ignores fields. Fields are not copied to the destination.

Overrides:

visitField in class jodd.asm5.ClassVisitor

visitAnnotation

public jodd.asm5.AnnotationVisitor visitAnnotation(java.lang.String desc,
                                                   boolean visible)

Copies all destination type annotations to the target.

Overrides:

visitAnnotation in class jodd.asm5.ClassVisitor

visitEnd

public void visitEnd()

Finalizes creation of destination proxy class.

Overrides:

visitEnd in class jodd.asm5.ClassVisitor

makeStaticInitBlock

protected void makeStaticInitBlock()

Creates static initialization block that simply calls all advice static init methods in correct order.

makeProxyConstructor

protected void makeProxyConstructor()

Creates init method that simply calls all advice constructor methods in correct order. This created init method is called from each destination's constructor.

processSuperMethods

protected void processSuperMethods()

Checks for all public super methods that are not overridden.

visitSource

public void visitSource(java.lang.String source,
                        java.lang.String debug)

Visits the source of the class (not used).

Overrides:

visitSource in class jodd.asm5.ClassVisitor

visitOuterClass

public void visitOuterClass(java.lang.String owner,
                            java.lang.String name,
                            java.lang.String desc)

Visits the enclosing class of the class (not used).

Overrides:

visitOuterClass in class jodd.asm5.ClassVisitor

visitAttribute

public void visitAttribute(jodd.asm5.Attribute attr)

Visits a non standard attribute of the class (not used).

Overrides:

visitAttribute in class jodd.asm5.ClassVisitor

visitInnerClass

public void visitInnerClass(java.lang.String name,
                            java.lang.String outerName,
                            java.lang.String innerName,
                            int access)

Visits information about an inner class (not used).

Overrides:

visitInnerClass in class jodd.asm5.ClassVisitor

applyProxy

protected ProxettaMethodBuilder applyProxy(MethodSignatureVisitor msign)

Check if proxy should be applied on method and return proxy method builder if so. Otherwise, returns null.

matchMethodPointcuts

protected java.util.List<jodd.proxetta.asm.ProxyAspectData> matchMethodPointcuts(MethodSignatureVisitor msign)

Matches pointcuts on method. If no pointcut found, returns null.
