All Implemented Interfaces:
ClassVisitor

public class CheckClassAdapter
extends ClassAdapter

A ClssAdapter that checks that its methods are properly used. More precisely this class adapter checks each method call individually, based only on its arguments, but does not check the sequence of method calls. For example, the invalid sequence visitField(ACC_PUBLIC, "i", "I", null) visitField(ACC_PUBLIC, "i", "D", null) will not be detected by this class adapter.

Method Detail

visit

public void visit(int access,
                  String name,
                  String superName,
                  String[] interfaces,
                  String sourceFile)
Description copied from interface: ClassVisitor
Visits the header of the class.

Specified by:
visit in interface ClassVisitor
Overrides:
visit in class ClassAdapter

visitInnerClass

public void visitInnerClass(String name,
                            String outerName,
                            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
Overrides:
visitInnerClass in class ClassAdapter

visitField

public void visitField(int access,
                       String name,
                       String desc,
                       Object value,
                       Attribute attrs)
Description copied from interface: ClassVisitor
Visits a field of the class.

Specified by:
visitField in interface ClassVisitor
Overrides:
visitField in class ClassAdapter

visitMethod

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

                               Attribute attrs)
Description copied from interface: ClassVisitor
Visits a method of the class. This method must return a new CodeVisitor instance (or null) each time it is called, i.e., it should not return a previously returned visitor.

Specified by:
visitMethod in interface ClassVisitor
Overrides:
visitMethod in class ClassAdapter

visitAttribute

public void visitAttribute(Attribute attr)
Description copied from interface: ClassVisitor
Visits a non standard attribute of the class. This method must visit only the first attribute in the given attribute list.

Specified by:
visitAttribute in interface ClassVisitor
Overrides:
visitAttribute in class ClassAdapter

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
Overrides:
visitEnd in class ClassAdapter
