public class CheckClassAdapter
A ClassAdapter
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.

- the class version.access
- the class's access flags (see Constants
). This
parameter also indicates if the class is deprecated.name
- the internal name of the class (see getInternalName

- the internal of name of the super class (see getInternalName
). For interfaces, the super

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

compiled. May be null.public void visitInnerClass(java.lang.String name, java.lang.String outerName, java.lang.String innerName, int access)

- the internal name of an inner class (see getInternalName
).outerName
- the internal name of the class to which the inner class
belongs (see getInternalName

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

null if the field does not have an initial value, must be an
Integer
