Opaque handle to a cycle within a GenericCycleInfo that wraps the cycle's preorder index. Handles remain valid as long as the cycle forest is not recomputed; addBlockToCycle() adds a block but never adds, removes, or reorders cycles, so it leaves every handle valid.

class CycleRef;| Name | Description |
|---|---|
CycleRef [constructor] | Construct an invalid cycle handle. |
isValid | Return true if this handle names a real cycle. |
operator bool | Return true if this handle names a real cycle. |
operator== | Return true if both handles name the same cycle index. |
operator!= | Return true if the handles name different cycle indices. |
