| ClassVisitor | | public interface ClassVisitor (Code) | | A visitor to visit a Java class. The methods of this interface must be called
in the following order: visit [ visitSource ] [
visitOuterClass ] ( visitAnnotation |
visitAttribute )* (visitInnerClass |
visitField | visitMethod )* visitEnd.

| Method Summary | |
| void | visit(int version, int access, String name, String signature, String superName, String[] interfaces)
Visits the header of the class.
Parameters:
version - the class version.
Parameters:
access - the class's access flags (see Opcodes). | | AnnotationVisitor | visitAnnotation(String desc, boolean visible)
Visits an annotation of the class.
Parameters:
desc - the class descriptor of the annotation class.
Parameters:
visible - true if the annotation is visible at runtime. | | void | visitAttribute(Attribute attr)
Visits a non standard attribute of the class. | | void | visitEnd()
Visits the end of the class. | | FieldVisitor | visitField(int access, String name, String desc, String signature, Object value)
Visits a field of the class.
Parameters:
access - the field's access flags (see Opcodes). | | void | visitInnerClass(String name, String outerName, String innerName, int access)
Visits information about an inner class. | | MethodVisitor | visitMethod(int access, String name, String desc, String signature, String[] exceptions)
Visits a method of the class. | | void | visitOuterClass(String owner, String name, String desc)
Visits the enclosing class of the class. | | void | visitSource(String source, String debug)
Visits the source of the class.
Parameters:
source - the name of the source file from which the class wascompiled. |
| visit | | void visit(int version, int access, String name, String signature, String superName, String[] interfaces)(Code) | | Visits the header of the class.
Parameters:
version - the class version.
Parameters:
access - the class's access flags (see Opcodes). Thisparameter also indicates if the class is deprecated.
Parameters:
name - the internal name of the class (seeType.getInternalName getInternalName).
Parameters:
signature - the signature of this class. May be null ifthe class is not a generic one, and does not extend or implementgeneric classes or interfaces.
Parameters:
superName - the internal of name of the super class (seeType.getInternalName getInternalName). For interfaces,the super class is Object. May be null, butonly for the Object class.
Parameters:
interfaces - the internal names of the class's interfaces (seeType.getInternalName getInternalName). May benull. |
| visitAnnotation | | AnnotationVisitor visitAnnotation(String desc, boolean visible)(Code) | | Visits an annotation of the class.
Parameters:
desc - the class descriptor of the annotation class.
Parameters:
visible - true if the annotation is visible at runtime. a non null visitor to visit the annotation values. |
| visitAttribute | | void visitAttribute(Attribute attr)(Code) | | Visits a non standard attribute of the class.
Parameters:
attr - an attribute. |
| visitEnd | | void visitEnd()(Code) | | 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.
|
| visitField | | FieldVisitor visitField(int access, String name, String desc, String signature, Object value)(Code) | | Visits a field of the class.
Parameters:
access - the field's access flags (see Opcodes). Thisparameter also indicates if the field is synthetic and/ordeprecated.
Parameters:
name - the field's name.
Parameters:
desc - the field's descriptor (see Type Type).
Parameters:
signature - the field's signature. May be null if thefield's type does not use generic types.
Parameters:
value - the field's initial value. This parameter, which may benull if the field does not have an initial value, mustbe an Integer, a Float, a Long, aDouble or a String (for int,float, long or String fieldsrespectively). This parameter is only used for static fields.Its value is ignored for non static fields, which must beinitialized through bytecode instructions in constructors ormethods. a visitor to visit field annotations and attributes, ornull if this class visitor is not interested invisiting these annotations and attributes. |
| visitInnerClass | | void visitInnerClass(String name, String outerName, String innerName, int access)(Code) | | Visits information about an inner class. This inner class is not
necessarily a member of the class being visited.
Parameters:
name - the internal name of an inner class (seeType.getInternalName getInternalName).
Parameters:
outerName - the internal name of the class to which the inner classbelongs (see Type.getInternalName getInternalName). Maybe null.
Parameters:
innerName - the (simple) name of the inner class inside itsenclosing class. May be null for anonymous innerclasses.
Parameters:
access - the access flags of the inner class as originally declaredin the enclosing class. |
| visitMethod | | MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions)(Code) | | 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.
Parameters:
access - the method's access flags (see Opcodes). Thisparameter also indicates if the method is synthetic and/ordeprecated.
Parameters:
name - the method's name.
Parameters:
desc - the method's descriptor (see Type Type).
Parameters:
signature - the method's signature. May be null if themethod parameters, return type and exceptions do not use generictypes.
Parameters:
exceptions - the internal names of the method's exception classes(see Type.getInternalName getInternalName). May benull. an object to visit the byte code of the method, or nullif this class visitor is not interested in visiting the code ofthis method. |
| visitOuterClass | | void visitOuterClass(String owner, String name, String desc)(Code) | | Visits the enclosing class of the class. This method must be called only
if the class has an enclosing class.
Parameters:
owner - internal name of the enclosing class of the class.
Parameters:
name - the name of the method that contains the class, ornull if the class is not enclosed in a method of itsenclosing class.
Parameters:
desc - the descriptor of the method that contains the class, ornull if the class is not enclosed in a method of itsenclosing class. |
| visitSource | | void visitSource(String source, String debug)(Code) | | Visits the source of the class.
Parameters:
source - the name of the source file from which the class wascompiled. May be null.
Parameters:
debug - additional debug information to compute the correspondancebetween source and compiled elements of the class. May benull. |
