Specified by:

isExitBlock in interface IBasicBlock<SSAInstruction>

Returns:

true if the basic block represents the unique exit block.

isEntryBlock

boolean isEntryBlock()

Does this block represent the unique entry to a ControlFlowGraph

Specified by:

isEntryBlock in interface IBasicBlock<SSAInstruction>

Returns:

true if the basic block represents the unique entry block.
