Member Function Documentation

_insertWriteIntent()

void mongo::dur::CommitJob::_insertWriteIntent ( void *  p, int  len  )

inlineprivate

bytes()

size_t mongo::dur::CommitJob::bytes ( ) const

inline

We check how much written and if it is getting to be a lot, we commit sooner.

committingReset()

void mongo::dur::CommitJob::committingReset

(

)

We use the commitjob object over and over, calling committingReset() rather than reconstructing.

getIntentsSorted()

const WriteIntentsVector& mongo::dur::CommitJob::getIntentsSorted ( )

inline

Sorts the internal list of write intents so that overlapping and duplicate items can be merged.

We do the sort here so the caller receives something they must keep const from their POV.

hasWritten()

bool mongo::dur::CommitJob::hasWritten ( ) const

inline

When this value is false we don't have to do any group commit.

MONGO_DISALLOW_COPYING()

mongo::dur::CommitJob::MONGO_DISALLOW_COPYING ( CommitJob  )

private

note()

void mongo::dur::CommitJob::note	(	void *	p,
		int	len
	)

Record/note an intent to write.

NOTE: Not thread safe. Requires the mutex to be locked.

noteOp()

void mongo::dur::CommitJob::noteOp

(

std::shared_ptr< DurOp >

p

)

Note an operation other than a "basic write".

ops()

const DurOpsVector& mongo::dur::CommitJob::ops ( ) const

inline
