Constructor Details
- CHECKCAST
  
  public CHECKCAST(int index)
  
  Check whether object is of given type
  
  Parameters:
  
  index - index to class in constant pool
Method Details
- getExceptions
  
  public 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
