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 interfaceIBasicBlock<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 interfaceIBasicBlock<SSAInstruction>
- Returns:
- the instruction index for the last instruction in the basic block
-
isCatchBlock
public boolean isCatchBlock()
Description copied from interface:IBasicBlock
Return true if the basic block represents a catch block.- Specified by:
isCatchBlock
in interfaceIBasicBlock<SSAInstruction>
- Returns:
- true if the basic block represents a catch block.
-
toString
public String toString()
- Overrides:
toString
in classObject
- See Also:
Object.toString()
-
isExitBlock
public boolean isExitBlock()
Description copied from interface:IBasicBlock
Return true if the basic block represents the unique exit block.- Specified by:
isExitBlock
in interfaceIBasicBlock<SSAInstruction>
- 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 interfaceIBasicBlock<SSAInstruction>
- Returns:
- true if the basic block represents the unique entry block.
-
getMethod
public IMethod getMethod()
- Specified by:
getMethod
in interfaceIBasicBlock<SSAInstruction>
- Returns:
- governing method for this block
-
endsInPEI
public boolean endsInPEI()
-
endsInReturn

-
getNumber
public int getNumber()
Description copied from interface:IBasicBlock
Each basic block should have a unique number in its cfg- Specified by:
getNumber
in interfaceIBasicBlock<SSAInstruction>
- Returns:
- the basic block's number
-
iterator
