- Method Detail
  - getNumberOfUses
```
public int getNumberOfUses()
```
    Overrides:
    
    getNumberOfUses in class SSAInstruction
  - getUse
```
public int getUse(int j)
```
    Overrides:
    
    getUse in class SSAInstruction
    
    Returns:
    
    value number representing the jth use in this instruction. -1 means TOP (i.e., the value doesn't matter)

  - getArrayRef
```
public int getArrayRef()
```
    Return the value number of the array reference.
  - getIndex
```
public int getIndex()
```
    Return the value number of the index of the array reference.
  - getElementType
```
public TypeReference getElementType()
```
  - typeIsPrimitive
```
public boolean typeIsPrimitive()
```
    Returns:
    
    true iff this represents an array access of a primitive type element
  - isPEI
```
public boolean isPEI()
```
    Overrides:
    
    isPEI in class SSAInstruction
    
    Returns:
    
    true iff this instruction may throw an exception.
  - isFallThrough
```
public boolean isFallThrough()
```
    Specified by:
    
    isFallThrough in class SSAInstruction
    
    Returns:
    
    true iff this instruction may fall through to the next
