                  int offset,
                  int num)

Invoked when locals of stack_map_frame is visited.

stack

public int stack(int pos,
                 int offset,
                 int num)

Invoked when stack of stack_map_frame is visited.

typeInfoArray

public int typeInfoArray(int pos,
                         int offset,
                         int num,
                         boolean isLocals)

Invoked when an array of verification_type_info is visited.

Parameters:

num - the number of elements.

isLocals - true if this array is for locals. false if it is for stack.

typeInfo

public void typeInfo(int pos,
                     byte tag)

Invoked when an element of verification_type_info (except Object_variable_info and Uninitialized_variable_info) is visited.

objectVariable

public void objectVariable(int pos,
                           int clazz)

Invoked when an element of type Object_variable_info is visited.

uninitialized

public void uninitialized(int pos,
                          int offset)

Invoked when an element of type Uninitialized_variable_info is visited.
