◆ ~LedgerReplayTask()

ripple::LedgerReplayTask::~LedgerReplayTask ( )

Definition at line 110 of file LedgerReplayTask.cpp.

Member Function Documentation

◆ init()

void ripple::LedgerReplayTask::init ( )

Start the task.

Definition at line 116 of file LedgerReplayTask.cpp.

◆ addDelta()

void ripple::LedgerReplayTask::addDelta ( std::shared_ptr< LedgerDeltaAcquire > const & delta )

add a new LedgerDeltaAcquire subtask

Parameters

delta the new LedgerDeltaAcquire subtask

Note: the LedgerDeltaAcquire subtasks must be added in order

Definition at line 272 of file LedgerReplayTask.cpp.

◆ getTaskParameter()

TaskParameter const& ripple::LedgerReplayTask::getTaskParameter ( ) const

Definition at line 123 of file LedgerReplayTask.h.

◆ finished()

bool ripple::LedgerReplayTask::finished ( ) const

return if the task is finished

Definition at line 300 of file LedgerReplayTask.cpp.

◆ onTimer()

void ripple::LedgerReplayTask::onTimer	(	bool	progress,
		ScopedLockType &
	)

overrideprivatevirtual

Hook called from invokeOnTimer().

Implements ripple::TimeoutCounter.

Definition at line 250 of file LedgerReplayTask.cpp.

◆ pmDowncast()

std::weak_ptr< TimeoutCounter > ripple::LedgerReplayTask::pmDowncast ( )

overrideprivatevirtual

Return a weak pointer to this.

Implements ripple::TimeoutCounter.

Definition at line 266 of file LedgerReplayTask.cpp.

◆ updateSkipList()

void ripple::LedgerReplayTask::updateSkipList	(	uint256 const &	hash,
		std::uint32_t	seq,
		std::vector< uint256 > const &	sList
	)

private

Update this task (by a SkipListAcquire subtask) when skip list is ready.

Parameters

hash	hash of the ledger that has the skip list
seq	sequence number of the ledger that has the skip list
sList	skip list

Definition at line 226 of file LedgerReplayTask.cpp.

◆ deltaReady()

void ripple::LedgerReplayTask::deltaReady ( uint256 const & deltaHash )

private

Notify this task (by a LedgerDeltaAcquire subtask) that a delta is ready.

Parameters

deltaHash ledger hash of the delta

Definition at line 174 of file LedgerReplayTask.cpp.

◆ trigger()

void ripple::LedgerReplayTask::trigger ( ScopedLockType & sl )

private

Trigger another round.

Parameters

sl	lock. this function must be called with the lock

Definition at line 146 of file LedgerReplayTask.cpp.

◆ tryAdvance()

void ripple::LedgerReplayTask::tryAdvance ( ScopedLockType & sl )

private

Try to build more ledgers.

Parameters

sl	lock. this function must be called with the lock

Definition at line 184 of file LedgerReplayTask.cpp.

◆ cancel()

void ripple::TimeoutCounter::cancel ( )

virtualinherited

Cancel the task by marking it as failed if the task is not done.

Note: this function does not attempt to cancel the scheduled timer or to remove the queued job if any. When the timer expires or the queued job starts, however, the code will see that the task is done and returns immediately, if it can lock the weak pointer of the task.

Definition at line 118 of file TimeoutCounter.cpp.

◆ setTimer()

void ripple::TimeoutCounter::setTimer ( ScopedLockType & sl )

protectedinherited

Schedule a call to queueJob() after mTimerInterval.

Definition at line 50 of file TimeoutCounter.cpp.

◆ queueJob()

void ripple::TimeoutCounter::queueJob ( ScopedLockType & sl )

protectedinherited

Queue a job to call invokeOnTimer().

Definition at line 69 of file TimeoutCounter.cpp.

◆ isDone()

bool ripple::TimeoutCounter::isDone ( ) const

protectedinherited

Definition at line 116 of file TimeoutCounter.h.

◆ invokeOnTimer()

void ripple::TimeoutCounter::invokeOnTimer ( )

privateinherited

Calls onTimer() if in the right state.

Only called by queueJob().

Definition at line 93 of file TimeoutCounter.cpp.

◆ getCounter()

static auto& ripple::CountedObject< LedgerReplayTask >::getCounter
