```
public CHECKCAST(int index)
```
    Check whether object is of given type
    
    Parameters:
    
    index - index to class in constant pool
- Method Detail
  - getExceptions
```
public java.lang.Class<?>[] getExceptions()
```
    Specified by:
    
    getExceptions in interface ExceptionThrower
    
    Returns:
    
    exceptions this instruction may cause
  - getLoadClassType
```
public ObjectType getLoadClassType(ConstantPoolGen cpg)
```
    Description copied from interface: LoadClass
    
    Returns the ObjectType of the referenced class or interface that may be loaded and resolved.
    
    Specified by:
    
    getLoadClassType in interface LoadClass
    
    Returns:
    
    object type that may be loaded or null if a primitive is referenced
  - accept
```
public void accept(Visitor v)
```
    Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.
    
    Specified by:
    
    accept in class Instruction
    
    Parameters:
    
    v - Visitor object
