- Method Detail
  - getFirstInstructionIndex
```
public int getFirstInstructionIndex()
```
    Description copied from interface: IBasicBlock
    
    Get the index of the first instruction in the basic block. The value is an index into the instruction array that contains all the instructions for the method. If the result is < 0, the block has no instructions
    
    Specified by:
    
    getFirstInstructionIndex in interface IBasicBlock<T extends ISSABasicBlock>
    
    Returns:
    
    the instruction index for the first instruction in the basic block.
  - getLastInstructionIndex
```
public int getLastInstructionIndex()
```
    Description copied from interface: IBasicBlock
    
    Get the index of the last instruction in the basic block. The value is an index into the instruction array that contains all the instructions for the method. If the result is < 0, the block has no instructions
    
    Specified by:
    
    getLastInstructionIndex in interface IBasicBlock<T extends ISSABasicBlock>
    
    Returns:
    
    the instruction index for the last instruction in the basic block
