Classes
class	Galois::Runtime::Releasable
class	Galois::Runtime::Lockable
	All objects that may be locked (nodes primarily) must inherit from Lockable. More...
class	Galois::Runtime::LockManagerBase
class	Galois::Runtime::SimpleRuntimeContext
struct	Galois::Runtime::AlwaysLockObj
struct	Galois::Runtime::CheckedLockObj
Namespaces
namespace	Galois
	Main Galois namespace.
namespace	Galois::Runtime
	Internal Galois functionality - Use at your own risk.
Enumerations
enum	Galois::Runtime::ConflictFlag { Galois::Runtime::CONFLICT = -1, Galois::Runtime::NO_CONFLICT = 0, Galois::Runtime::REACHED_FAILSAFE = 1, Galois::Runtime::BREAK = 2 }
enum	Galois::Runtime::PendingFlag { Galois::Runtime::NON_DET, Galois::Runtime::PENDING, Galois::Runtime::COMMITTING }
Functions
void	Galois::Runtime::setPending (PendingFlag value)
	Used by deterministic and ordered executor.
PendingFlag	Galois::Runtime::getPending ()
static void	Galois::Runtime::clearConflictLock ()
	used to release lock over exception path
static void	Galois::Runtime::clearReleasable ()
SimpleRuntimeContext *	Galois::Runtime::getThreadContext ()
	get the current conflict detection class, may be null if not in parallel region
void	Galois::Runtime::setThreadContext (SimpleRuntimeContext *n)
	used by the parallel code to set up conflict detection per thread
bool	Galois::Runtime::shouldLock (const Galois::MethodFlag g)
	Helper function to decide if the conflict detection lock should be taken.
void	Galois::Runtime::doAcquire (Lockable *lockable)
	actual locking function. Will always lock.
void	Galois::Runtime::acquire (Lockable *lockable, Galois::MethodFlag m)
	Master function which handles conflict detection used to acquire a lockable thing.
void	Galois::Runtime::signalConflict (Lockable *)
void	Galois::Runtime::forceAbort ()
