  - LineNumberGen
```
public LineNumberGen(InstructionHandle ih,
                     int src_line)
```
    Create a line number.
    
    Parameters:
    
    ih - instruction handle to reference
- Method Detail
  - containsTarget
```
public boolean containsTarget(InstructionHandle ih)
```
    Specified by:
    
    containsTarget in interface InstructionTargeter
    
    Returns:
    
    true, if ih is target of this line number
  - updateTarget
```
public void updateTarget(InstructionHandle old_ih,
                         InstructionHandle new_ih)
```
    Specified by:
    
    updateTarget in interface InstructionTargeter
    
    Parameters:
    
    old_ih - old target
    
    new_ih - new target
  - getLineNumber
```
public LineNumber getLineNumber()
```
    Get LineNumber attribute . This relies on that the instruction list has already been dumped to byte code or or that the `setPositions' methods has been called for the instruction list.
  - setInstruction
```
public void setInstruction(InstructionHandle ih)
```
  - clone
```
public LineNumberGen clone()
```
    Overrides:
    
    clone in class java.lang.Object
  - getInstruction
```
public InstructionHandle getInstruction()
```
  - setSourceLine
```
public void setSourceLine(int src_line)
```
  - getSourceLine
```
public int getSourceLine()
```
