All Implemented Interfaces:

ClassVisitor

Direct Known Subclasses:

public class ClassAdapter
extends java.lang.Object
implements ClassVisitor

An empty ClassVisitor that delegates to another ClassVisitor. This class can be used as a super class to quickly implement usefull class adapter classes, just by overriding the necessary methods.

Constructor Detail

ClassAdapter

public ClassAdapter(ClassVisitor cv)

Constructs a new ClassAdapter object.

Parameters:

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)

Description copied from interface: ClassVisitor

Visits the header of the class.

Specified by:

visit in interface 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.

visitSource

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

Description copied from interface: ClassVisitor

Visits the source of the class.

Specified by:

visitSource in interface ClassVisitor

Parameters:

source - the name of the source file from which the class was compiled. May be null.

debug - additional debug information to compute the correspondance between source and compiled elements of the class. May be null.

visitOuterClass

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

Description copied from interface: ClassVisitor

Visits the enclosing class of the class. This method must be called only if the class has an enclosing class.

Specified by:

visitOuterClass in interface ClassVisitor

Parameters:

owner - internal name of the enclosing class of the class.

name - the name of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.

desc - the descriptor of the method that contains the class, or null if the class is not enclosed in a method of its enclosing class.

visitAnnotation

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

Description copied from interface: ClassVisitor

Visits an annotation of the class.

Specified by:

visitAnnotation in interface 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.

visitAttribute

public void visitAttribute(Attribute attr)

Description copied from interface: ClassVisitor

Visits a non standard attribute of the class.

Specified by:

visitAttribute in interface ClassVisitor

Parameters:

attr - an attribute.

visitInnerClass

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

Description copied from interface: ClassVisitor

Visits information about an inner class. This inner class is not necessarily a member of the class being visited.

Specified by:

visitInnerClass in interface ClassVisitor

Parameters:

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

outerName - the internal name of the class to which the inner class belongs (see getInternalName). May be null for not member classes.

innerName - the (simple) name of the inner class inside its enclosing class. May be null for anonymous inner classes.

access - the access flags of the inner class as originally declared in the enclosing class.

visitField

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

Description copied from interface: ClassVisitor

Visits a field of the class.

Specified by:

visitField in interface ClassVisitor

Parameters:

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

name - the field's name.

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

signature - the field's signature. May be null if the field's type does not use generic types.

value - the field's initial value. This parameter, which may be null if the field does not have an initial value, must be an Integer, a Float, a Long, a Double or a String (for int, float, long or String fields respectively). This parameter is only used for static fields. Its value is ignored for non static fields, which must be initialized through bytecode instructions in constructors or methods.

Returns:

a visitor to visit field annotations and attributes, or null if this class visitor is not interested in visiting these annotations and attributes.

visitMethod

public MethodVisitor visitMethod(int access,
                        java.lang.String name,
                        java.lang.String desc,

                        java.lang.String[] exceptions)

Description copied from interface: ClassVisitor

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 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 interface: 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.

Specified by:

visitEnd in interface ClassVisitor
