Functions

func LessByAccessCount 

func LessByAccessCount(bi, bj *CachedBlock) bool

LessByAccessCount defines higher priority CachedBlock as having been accessed more often.

func LessByAccessCountThenHeight 

func LessByAccessCountThenHeight(bi, bj *CachedBlock) bool

LessByAccessCountThenHeight compares access count with LessByAccessCount if the blocks have different accessTime values, otherwise it compares height with LessByHeight.

func LessByAccessTime 

func LessByAccessTime(bi, bj *CachedBlock) bool

LessByAccessTime defines higher priority CachedBlock as having a more recent access time. More recent accesses have a larger accessTime value (Unix time).

func LessByHeight 

func LessByHeight(bi, bj *CachedBlock) bool

LessByHeight defines a higher priority CachedBlock as having a higher height. That is, more recent blocks have higher priority than older blocks.

func MakeLessByAccessTimeThenCount 

func MakeLessByAccessTimeThenCount(millisecondsBinned int64) func(bi, bj *CachedBlock) bool

MakeLessByAccessTimeThenCount will create a CachedBlock comparison function given the specified time resolution in milliseconds. Two access times less than the given time apart are considered the same time, and access count is used to break the tie.

func WatchPriorityQueue 

func WatchPriorityQueue(bpq *BlockPriorityQueue)

WatchPriorityQueue is a hack since the priority of a CachedBlock is modified (if access or access time is in the LessFn) without triggering a reheap.

Types

type APICache

NOTE: The consumer of APICache should fill out MainChainBlocks before using it. For example, given a struct DB at height dbHeight with an APICache: 

 DB.APICache = NewAPICache(10000)
	DB.APICache.MainchainBlocks = make([]chainhash.Hash, 0, dbHeight+NExtra)
	for i := int64(0); i <= dbHeight; i++ {

func (*BlockPriorityQueue) SetLessFn 

func (pq *BlockPriorityQueue) SetLessFn(lessFn func(bi, bj *CachedBlock) bool)
