Types

type Analyser 

type Analyser interface {

	GetDBWriteCount() int
	GetDBReadCount() int
	GetNodeReadCount() int
	GetFlatKVReadTime() int
	GetFlatKVWriteTime() int

	Read  map[string][]byte
	Write map[string]DirtyValue
}

func NewCacheKvRWSet added in v1.6.7 

func NewCacheKvRWSet() CacheKVRWSet

type CacheKVStore 

type CacheKVStore interface {
	KVStore
	CacheManager
	// Writes operations to underlying KVStore
	Write()
	WriteWithSnapshotWSet() SnapshotWSet
	RevertDBWithSnapshotRWSet(set SnapshotWSet)
}

CacheKVStore cache-wraps a KVStore. After calling .Write() on the CacheKVStore, all previously created CacheKVStores on the object expire.

type CacheManager 

type CacheManager interface {
	IteratorCache(isdirty bool, cb func(key string, value []byte, isDirty bool, isDelete bool, storeKey StoreKey) bool, sKey StoreKey) bool
	// Clear the cache without writing
	Clear()
	DisableCacheReadList()
	GetRWSet(set MsRWSet)
}

type CacheMultiStore 

type CacheMultiStore interface {
	MultiStore
	CacheManager
	Write() // Writes operations to underlying KVStore
	WriteGetMultiSnapshotWSet() MultiSnapshotWSet
	RevertDBWithMultiSnapshotRWSet(set MultiSnapshotWSet)
}

From MultiStore.CacheMultiStore()....

type CacheMultiStoreResetter added in v1.5.4 

type CacheMultiStoreResetter interface {

func (si StoreInfo) GetHash() []byte

GetHash returns the GetHash from the CommitID. This is used in CommitInfo.Hash()

When we commit to this in a merkle proof, we create a map of storeInfo.Name -> storeInfo.GetHash() and build a merkle proof from that. This is then chained with the substore proof, so we prove the root hash from the substore before this and need to pass that (unmodified) as the leaf value of the multistore proof.
