All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`int`	`getFirstInstructionIndex()`	Get the index of the first instruction in the basic block.

`IMethod`	`getMethod()`
`int`	`getNumber()`	Each basic block should have a unique number in its cfg
`boolean`	`isCatchBlock()`	Return true if the basic block represents a catch block.
`boolean`	`isEntryBlock()`	Return true if the basic block represents the unique entry block.
`boolean`	`isExitBlock()`	Return true if the basic block represents the unique exit block.
`boolean`	`isHandlerBlock()`

  - getNumber
```
public int getNumber()
```
    Description copied from interface: IBasicBlock
    
    Each basic block should have a unique number in its cfg
    
    Specified by:
    
    getNumber in interface IBasicBlock<SSAInstruction>
    
    Returns:
    
    the basic block's number
  - getGraphNodeId
```
public int getGraphNodeId()
```
    Description copied from interface: INodeWithNumber
    
    A non-negative integer which serves as an identifier for this node in it's "dominant" graph. Initially this number is -1; a NumberedGraph will set it to a non-negative value when this node is inserted into the graph
    
    Specified by:
    
    getGraphNodeId in interface INodeWithNumber
    
    Returns:
    
    the identifier
  - setGraphNodeId
```
public void setGraphNodeId(int number)
```
    Specified by:
    
    setGraphNodeId in interface INodeWithNumber
  - 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<SSAInstruction>
    
    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<SSAInstruction>
    
    Returns:
    
    the instruction index for the last instruction in the basic block
  - isEntryBlock
```
public boolean isEntryBlock()
```
    Description copied from interface: IBasicBlock
    
    Return true if the basic block represents the unique entry block.
    
    Specified by:
    
    isEntryBlock in interface IBasicBlock<SSAInstruction>
    
    Returns:
    
    true if the basic block represents the unique entry block.
  - isExitBlock
```
public boolean isExitBlock()
```
    Description copied from interface: IBasicBlock
    
    Return true if the basic block represents the unique exit block.
    
    Specified by:
    
    isExitBlock in interface IBasicBlock<SSAInstruction>
    
    Returns:
    
    true if the basic block represents the unique exit block.
  - isHandlerBlock
```
public boolean isHandlerBlock()
```
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - isCatchBlock
```
public boolean isCatchBlock()
```
    Description copied from interface: IBasicBlock
    
    Return true if the basic block represents a catch block.
    
    Specified by:
    
    isCatchBlock in interface IBasicBlock<SSAInstruction>
    
    Returns:
    
    true if the basic block represents a catch block.

```
public IMethod getMethod()
```
    Specified by:
    
    getMethod in interface IBasicBlock<SSAInstruction>
    
    Returns:
    
    governing method for this block
