public class CheckClassAdapter extends ClassAdapter
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.cv| 构造器和说明 |

analysis.dump - true if bytecode should be printed out not only when errors
are found.pw - write where results going to be printedpublic void visit(int version,

ClassVisitorvisit 在接口中 ClassVisitorvisit 在类中 ClassAdapterversion - 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.public void visitSource(String file, String debug)
ClassVisitorvisitSource 在接口中 ClassVisitorvisitSource 在类中 ClassAdapterfile - 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.public void visitOuterClass(String owner, String name, String desc)
ClassVisitorvisitOuterClass 在接口中 ClassVisitorvisitOuterClass 在类中 ClassAdapterowner - 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.public void visitInnerClass(String name, String outerName, String innerName, int access)
ClassVisitorvisitInnerClass 在接口中 ClassVisitorvisitInnerClass 在类中 ClassAdaptername - 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.public FieldVisitor visitField(int access, String name, String desc, String signature, Object value)
ClassVisitorvisitField 在接口中 ClassVisitorvisitField 在类中 ClassAdapteraccess - 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.public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions)
ClassVisitorMethodVisitor instance (or null) each time it is
called, i.e., it should not return a previously returned visitor.visitMethod 在接口中 ClassVisitorvisitMethod 在类中 ClassAdapteraccess - 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.public AnnotationVisitor visitAnnotation(String desc, boolean visible)
ClassVisitorvisitAnnotation 在接口中 ClassVisitorvisitAnnotation 在类中 ClassAdapterdesc - the class descriptor of the annotation class.visible - true if the annotation is visible at runtime.public void visitAttribute(Attribute attr)
