  - visit
```
public void visit(SSAInstruction.IVisitor v)
           throws NullPointerException
```
    Description copied from class: SSAInstruction
    
    Apply an IVisitor to this instruction. We invoke the appropriate IVisitor method according to the type of this instruction.
    
    Specified by:
    
    visit in class SSAInstruction
    
    Throws:
    
    NullPointerException
    
    See Also:
    
    SSAInstruction.visit(IVisitor)
  - hasDef
```
public boolean hasDef()
```
    Description copied from class: SSAInstruction
    
    Does this instruction define a normal value, as distinct from a set of exceptions possibly thrown by it (e.g. for invoke instructions).
    
    Overrides:
    
    hasDef in class SSAInstruction
    
    Returns:
    
    true if the instruction does define a proper value.

```
    Description copied from class: SSAInstruction
    
    Return the ith def
    
    Overrides:
    
    getDef in class SSAInstruction
    
    Parameters:
    
    i - number of the def, starting at 0.
  - getNumberOfUses
```
public int getNumberOfUses()

    Returns:
    
    value number representing the jth use in this instruction. -1 means TOP (i.e., the value doesn't matter)
    
    See Also:
    
    SSAInstruction.getUse(int)
  - hashCode

  - isFallThrough
```
public boolean isFallThrough()
```
    Specified by:
    
    isFallThrough in class SSAInstruction
    
    Returns:
    
    true iff this instruction may fall through to the next
