Class BeanClassAdapter

java.lang.Object
  extended by org.objectweb.asm.ClassAdapter
      extended by org.objectweb.easybeans.enhancer.bean.BeanClassAdapter
All Implemented Interfaces:
org.objectweb.asm.ClassVisitor, org.objectweb.asm.Opcodes

public class BeanClassAdapter
extends org.objectweb.asm.ClassAdapter
implements org.objectweb.asm.Opcodes

This class adds a bean interface to the parsed object.
It also adds getEasyBeansFactory method defined in the EasyBeansBean interface.

Constructor Detail

BeanClassAdapter

public BeanClassAdapter(ClassAnnotationMetadata classAnnotationMetadata,
                        org.objectweb.asm.ClassVisitor cv)
Constructor.

Parameters:
classAnnotationMetadata - object containing all attributes of the class
cv - the class visitor to which this adapter must delegate calls.
Method Detail

visit

public void visit(int version,
                  int access,
                  java.lang.String name,
                  java.lang.String signature,
                  java.lang.String superName,
                  java.lang.String[] interfaces)
Visits the header of the class.

Specified by:
visit in interface org.objectweb.asm.ClassVisitor
Overrides:
visit in class org.objectweb.asm.ClassAdapter
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.

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)
Visits a method of the class. This method must return a new MethodVisitor instance (or null) each time it is called, i.e., it should not return a previously returned visitor.

Specified by:
visitMethod in interface org.objectweb.asm.ClassVisitor
Overrides:
visitMethod in class org.objectweb.asm.ClassAdapter
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()
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.

Specified by:
visitEnd in interface org.objectweb.asm.ClassVisitor
Overrides:
visitEnd in class org.objectweb.asm.ClassAdapter

addTimerMethod

private void addTimerMethod(org.objectweb.asm.ClassVisitor cv)
This method will call the timeout method (if any).
The timeout method may be defined on the super class. If there is no timeout method defined on the bean, throw an exception

Parameters:
cv - the class visitor.
