```
public InsnList()
```
- Method Detail
  - size
```
public int size()
```
    Returns the number of instructions in this list.
    
    Returns:
    the number of instructions in this list.
  - getFirst
```
public AbstractInsnNode getFirst()
```
    Returns the first instruction in this list.
    
    Returns:
    the first instruction in this list, or null if the list is empty.
  - getLast
```
public AbstractInsnNode getLast()
```
    Returns the last instruction in this list.
    
    Returns:
    the last instruction in this list, or null if the list is empty.
  - get
```
public AbstractInsnNode get(int index)
```
    Returns the instruction whose index is given. This method builds a cache of the instructions in this list to avoid scanning the whole list each time it is called. Once the cache is built, this method run in constant time. This cache is invalidated by all the methods that modify the list.
    
    Parameters:
    index - the index of the instruction that must be returned.
    
    Returns:
    the instruction whose index is given.
    
    Throws:
    
    IndexOutOfBoundsException - if (index < 0 || index >= size()).
  - contains
```
public boolean contains(AbstractInsnNode insn)
```
    Returns true if the given instruction belongs to this list. This method always scans the instructions of this list until it finds the given instruction or reaches the end of the list.
    
    Parameters:
    insn - an instruction.
    
    Returns:
    true if the given instruction belongs to this list.
  - indexOf
```
public int indexOf(AbstractInsnNode insn)
```
    Returns the index of the given instruction in this list. This method builds a cache of the instruction indexes to avoid scanning the whole list each time it is called. Once the cache is built, this method run in constant time. The cache is invalidated by all the methods that modify the list.
    
    Parameters:
    insn - an instruction of this list.
    
    Returns:
    the index of the given instruction in this list. The result of this method is undefined if the given instruction does not belong to this list. Use contains to test if an instruction belongs to an instruction list or not.
  - accept
```
public void accept(MethodVisitor mv)
```
    Makes the given visitor visit all of the instructions in this list.
    
    Parameters:
    mv - the method visitor that must visit the instructions.
  - iterator
```
public ListIterator<AbstractInsnNode> iterator()
```
    Returns an iterator over the instructions in this list.
    
    Returns:
    an iterator over the instructions in this list.
  - iterator
```
public ListIterator<AbstractInsnNode> iterator(int index)
```
    Returns an iterator over the instructions in this list.
    
    Returns:
    an iterator over the instructions in this list.
  - toArray
```
public AbstractInsnNode[] toArray()
```
    Returns an array containing all of the instructions in this list.
    
    Returns:
    an array containing all of the instructions in this list.
  - set
```
public void set(AbstractInsnNode location,
       AbstractInsnNode insn)
```
    Replaces an instruction of this list with another instruction.
    
    Parameters:
    location - an instruction of this list.
    insn - another instruction, which must not belong to any InsnList.
  - add
```
public void add(AbstractInsnNode insn)
```
    Adds the given instruction to the end of this list.
    
    Parameters:
    insn - an instruction, which must not belong to any InsnList.
  - add
```
public void add(InsnList insns)
```
    Adds the given instructions to the end of this list.
    
    Parameters:
    insns - an instruction list, which is cleared during the process. This list must be different from 'this'.
  - insert
```
public void insert(AbstractInsnNode insn)
```
    Inserts the given instruction at the begining of this list.
    
    Parameters:
    insn - an instruction, which must not belong to any InsnList.
  - insert
```
public void insert(InsnList insns)
```
    Inserts the given instructions at the begining of this list.
    
    Parameters:
    insns - an instruction list, which is cleared during the process. This list must be different from 'this'.
  - insert
```
public void insert(AbstractInsnNode location,
          AbstractInsnNode insn)
```
    Inserts the given instruction after the specified instruction.
    
    Parameters:
    location - an instruction of this list after which insn must be inserted.
    insn - the instruction to be inserted, which must not belong to any InsnList.
  - insert
```
public void insert(AbstractInsnNode location,
          InsnList insns)
```
    Inserts the given instructions after the specified instruction.
    
    Parameters:
    location - an instruction of this list after which the instructions must be inserted.
    insns - the instruction list to be inserted, which is cleared during the process. This list must be different from 'this'.
  - insertBefore
```
public void insertBefore(AbstractInsnNode location,
                AbstractInsnNode insn)
```
    Inserts the given instruction before the specified instruction.
    
    Parameters:
    location - an instruction of this list before which insn must be inserted.
    insn - the instruction to be inserted, which must not belong to any InsnList.
  - insertBefore
```
public void insertBefore(AbstractInsnNode location,
                InsnList insns)
