class ValidatorLockClassState

Defined at line 86 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

A derivative of MetadataLockClassState that provides full state necessary for

runtime lock validation. This type is used when lock validation is enabled at

compile time.

Public Methods

void ValidatorLockClassState (const fxt::InternedString & name, LockFlags flags)

Constructs an instance of ValidatorLockClassState.

Defined at line 89 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

void ValidatorLockClassState (const ValidatorLockClassState & )

Disable copy construction / assignment.

ValidatorLockClassState * Get (LockClassId id)

Returns the ValidatorLockClassState instance for the given lock class id.

The id must be a valid lock class id. This method intentionally shadows

MetadataLockClassState::Get.

bool IsIrqSafe (LockClassId id)

Returns true if the given lock class is irq-safe, false otherwise.

Defined at line 105 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool IsNestable (LockClassId id)

Returns true if the given lock class is nestable, false otherwise.

Defined at line 108 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool IsMultiAcquire (LockClassId id)

Returns true if the given lock class is multi-acquire, false otherwise.

Defined at line 111 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool IsLeaf (LockClassId id)

Defined at line 115 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool IsReportingDisabled (LockClassId id)

Returns true if reporting is disabled for the given lock class, false

otherwise.

Defined at line 119 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool IsReAcquireFatal (LockClassId id)

Returns true if the validator should abort the program if it detects an

invalid re-acquire with this lock class.

Defined at line 125 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool IsActiveListDisabled (LockClassId id)

Returns true if the lock should not be added to the active lock list

during an acquire.

Defined at line 131 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool IsTrackingDisabled (LockClassId id)

Returns true if the lock should not be tracked.

Defined at line 136 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

bool HasLockClass (LockClassId id, LockClassId search_id)

Returns true if lock class given by |search_id| is in the dependency set of

the lock class given by |id|, false otherwise.

Defined at line 142 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

LockResult AddLockClass (LockClassId id, LockClassId add_id)

Adds the lock class given by |add_id| to the dependency set of the lock

class given by |id|.

Defined at line 148 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

LockFlags flags ()

Return the flags of this lock class.

Defined at line 153 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

Iterator Iter ()

Returns an iterator for the init-time linked list of state instances.

Defined at line 178 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

const LockDependencySet & dependency_set ()

Returns the dependency set for this lock class.

uint64_t least ()

Defined at line 186 of file ../../zircon/system/ulib/lockdep/include/lockdep/lock_class_state.h

void Reset ()

Resets the dependency set and disjoint set of this object. This is

primarily used to initialize the state between successive tests.
