public AnnotationInfo getClassAnnotationInfo()

getInterfaceTransactionalInfo

public AnnotationInfo getInterfaceTransactionalInfo(String methodName,
                                                    String methodDesc)

Returns Transactional information from a matching interface method.

Returns null if no matching (transactional) interface method was found.

Parameters:

methodName - The method name

methodDesc - The method description

visit

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

Visit the class with interfaces.

Overrides:

visit in class ClassVisitor

Parameters:

version - the class version.

access - the class's access flags (see Opcodes). This parameter also indicates if the class is deprecated.

name - the internal name of the class (see getInternalName).

signature - the signature of this class. May be null if the class is not a generic one, and does not extend or implement generic classes or interfaces.

superName - the internal of name of the super class (see getInternalName). For interfaces, the super class is Object. May be null, but only for the Object class.

interfaces - the internal names of the class's interfaces (see getInternalName). May be null.

visitAnnotation

public AnnotationVisitor visitAnnotation(String desc,
                                         boolean visible)

Visit class level annotations.

Overrides:

visitAnnotation in class ClassVisitor

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.

visitMethod

public MethodVisitor visitMethod(int access,
                                 String name,
                                 String desc,

                                 String[] exceptions)

Visit the methods specifically looking for method level transactional annotations.

Overrides:

visitMethod in class ClassVisitor

Parameters:

access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.

name - the method's name.

desc - the method's descriptor (see Type).

signature - the method's signature. May be null if the method parameters, return type and exceptions do not use generic types.

exceptions - the internal names of the method's exception classes (see getInternalName). May be null.

Returns:

an object to visit the byte code of the method, or null if this class visitor is not interested in visiting the code of this method.

visitEnd

public void visitEnd()

Description copied from class: ClassVisitor

Visits the end of the class. This method, which is the last one to be called, is used to inform the visitor that all the fields and methods of the class have been visited.
