```
public BasicBlock(int startIndex)
```
- Method Detail
  - 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<Instruction>
    
    Returns:
    
    true if the basic block represents a catch block.
  - addExceptionalEdges
```
protected void addExceptionalEdges(Instruction last)
```
    Add any exceptional edges generated by the last instruction in a basic block.
    
    Parameters:
    
    last - the last instruction in a basic block.
  - getImplicitExceptionTypes
```
public Collection<TypeReference> getImplicitExceptionTypes(Instruction pei)
```
    Parameters:
    
    pei - a potentially-excepting instruction
    
    Returns:
    the exception types that pei may throw, independent of the class hierarchy. null if none. Notes
    
    this method will NOT return the exception type explicitly thrown by an athrow
    this method will NOT return the exception types that a called method may throw
    this method ignores OutOfMemoryError
    this method ignores linkage errors
    this method ignores IllegalMonitorState exceptions
    Throws:
    
    IllegalArgumentException - if pei is null
  - 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<Instruction>
    
    Returns:
    
    the instruction index for the last instruction in the basic block
  - 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<Instruction>
    
    Returns:
    
    the instruction index for the first instruction in the basic block.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - 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<Instruction>
    
    Returns:
    
    true if the basic block represents the unique exit 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<Instruction>
    
    Returns:
    
    true if the basic block represents the unique entry block.
  - getMethod
```
public IMethod getMethod()
```
    Specified by:
    
    getMethod in interface IBasicBlock<Instruction>
    
    Returns:
    
    governing method for this block
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - getNumber
```

    Each basic block should have a unique number in its cfg
    
    Specified by:
    
    getNumber in interface IBasicBlock<Instruction>
    
    Returns:
    
    the basic block's number
  - iterator
