Constructor Detail

ProxettaCreator

public ProxettaCreator(ProxyAspect... aspects)

Method Detail

accept

public ProxettaCreator accept(java.io.InputStream in)

accept

public ProxettaCreator accept(java.lang.String targetName)

accept

public ProxettaCreator accept(java.lang.Class target)

toByteArray

public byte[] toByteArray()

Returns raw bytecode.

isProxyApplied

public boolean isProxyApplied()

Returns true if at least one method was wrapped.

getProxyClassName

public java.lang.String getProxyClassName()

Returns proxy class name.

setVariableClassName

public void setVariableClassName(boolean varname)

If true class name will vary for each creation. This prevents java.lang.LinkageError: duplicate class definition.

destinationReady

protected void destinationReady()

Invoked after destination class is ready for manipulation.

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 for current target class. Upon creation, destinationReady() is invoked.

Specified by:

visit in interface org.objectweb.asm.ClassVisitor

Overrides:

visit in class EmptyVisitor

visitMethod

public org.objectweb.asm.MethodVisitor visitMethod(int access,
                                                   java.lang.String name,
                                                   java.lang.String desc,
                                                   java.lang.String signature,
                                                   java.lang.String[] exceptions)

Creates methods and constructors.

Destination proxy will have all constructors as a target class, using ProxettaCreator.ConstructorBuilder.

For a method, ProxettaCreator.MethodBuilder first determines if method matches pointcut. If so, method will be proxified.

Specified by:

visitMethod in interface org.objectweb.asm.ClassVisitor

Overrides:

visitMethod in class EmptyVisitor

visitAnnotation

public org.objectweb.asm.AnnotationVisitor visitAnnotation(java.lang.String signature,
                                                           boolean b)

Copies all destination type annotations to the target.

Specified by:

visitAnnotation in interface org.objectweb.asm.ClassVisitor

Specified by:

visitAnnotation in interface org.objectweb.asm.FieldVisitor

Specified by:

visitAnnotation in interface org.objectweb.asm.MethodVisitor

Overrides:

visitAnnotation in class EmptyVisitor

visitEnd

public void visitEnd()

Finalize destination proxy class.

Specified by:

visitEnd in interface org.objectweb.asm.ClassVisitor

Specified by:

visitEnd in interface org.objectweb.asm.FieldVisitor

Specified by:

visitEnd in interface org.objectweb.asm.MethodVisitor

Overrides:
