Functions

func GetCommitVersions added in v1.5.4 

func GetCommitVersions(db dbm.DB) ([]int64, error)

func HasVersion added in v1.5.4 

func HasVersion(db dbm.DB, version int64) (bool, error)

func LoadStore 

func LoadStore(db dbm.DB, flatKVDB dbm.DB, id types.CommitID, lazyLoading bool, startVersion int64) (types.CommitKVStore, error)

LoadStore returns an IAVL Store as a CommitKVStore. Internally, it will load the store's version (id) from the provided DB. An error is returned if the version fails to load.

func LoadStoreWithInitialVersion 

func LoadStoreWithInitialVersion(db dbm.DB, flatKVDB dbm.DB, id types.CommitID, lazyLoading bool, initialVersion uint64, upgradeVersion uint64) (types.CommitKVStore, error)

LoadStoreWithInitialVersion returns an IAVL Store as a CommitKVStore setting its initialVersion to the one given. Internally, it will load the store's version (id) from the provided DB. An error is returned if the version fails to load.

Types

type Store 

type Store struct {
	// contains filtered or unexported fields
}

Store Implements types.KVStore and CommitKVStore.

func UnsafeNewStore 

func UnsafeNewStore(tree *iavl.MutableTree) *Store

UnsafeNewStore returns a reference to a new IAVL Store with a given mutable IAVL tree reference. It should only be used for testing purposes.

CONTRACT: The IAVL tree should be fully loaded. CONTRACT: PruningOptions passed in as argument must be the same as pruning options passed into iavl.MutableTree

func (*Store) CacheWrap 

func (st *Store) CacheWrap() types.CacheWrap

Implements Store.

func (*Store) CacheWrapWithTrace 

func (st *Store) CacheWrapWithTrace(w io.Writer, tc types.TraceContext) types.CacheWrap

CacheWrapWithTrace implements the Store interface.

func (*Store) CommitterCommit added in v1.1.6 

func (st *Store) CommitterCommit(inputDelta *iavl.TreeDelta) (types.CommitID, *iavl.TreeDelta)

func (*Store) CurrentVersion added in v1.6.1 

func (st *Store) CurrentVersion() int64

func (*Store) Delete 

func (st *Store) Delete(key []byte)

Implements types.KVStore.

func (*Store) DeleteVersions 

func (st *Store) DeleteVersions(versions ...int64) error

DeleteVersions deletes a series of versions from the MutableTree. An error is returned if any single version is invalid or the delete fails. All writes happen in a single batch with a single commit.

func (*Store) EndTiming added in v1.6.7 

func (st *Store) EndTiming(tag string)

func (*Store) Export 

func (st *Store) Export(version int64) (*iavl.Exporter, error)

Exports the IAVL store at the given version, returning an iavl.Exporter for the tree.

func (*Store) Get 

func (st *Store) Get(key []byte) []byte

Implements types.KVStore.

func (*Store) GetDBReadCount 

func (st *Store) GetDBReadCount() int

func (*Store) GetDBReadTime 

func (st *Store) GetDBReadTime() int

func (*Store) GetDBWriteCount 

func (st *Store) GetDBWriteCount() int

func (*Store) GetEmptyImmutable added in v1.5.5 

func (st *Store) GetEmptyImmutable() *Store

GetEmptyImmutable returns an empty immutable IAVL tree

func (*Store) GetFlatKVReadCount added in v1.1.5 

func (st *Store) GetFlatKVReadCount() int

func (*Store) GetFlatKVReadTime added in v1.1.5 

func (st *Store) GetFlatKVReadTime() int

func (*Store) GetFlatKVWriteCount added in v1.1.5 

func (st *Store) GetFlatKVWriteCount() int

func (*Store) GetFlatKVWriteTime added in v1.1.5 

func (st *Store) GetFlatKVWriteTime() int

func (*Store) GetHeights added in v1.0.0 

func (st *Store) GetHeights() map[int64][]byte

func (*Store) GetImmutable 

func (st *Store) GetImmutable(version int64) (*Store, error)

GetImmutable returns a reference to a new store backed by an immutable IAVL tree at a specific version (height) without any pruning options. This should be used for querying and iteration only. If the version does not exist or has been pruned, an empty immutable IAVL tree will be used. Any mutable operations executed will result in a panic.

func (*Store) GetNodeReadCount 

func (st *Store) GetNodeReadCount() int

func (*Store) GetStoreType 

func (st *Store) GetStoreType() types.StoreType

Implements Store.

func (*Store) GetUpgradeVersion added in v1.3.0 

func (st *Store) GetUpgradeVersion() int64

func (*Store) Has 

func (st *Store) Has(key []byte) (exists bool)

Implements types.KVStore.

func (*Store) Import 

func (st *Store) Import(version int64) (*iavl.Importer, error)

Import imports an IAVL tree at the given version, returning an iavl.Importer for importing.

func (*Store) Iterator 

func (st *Store) Iterator(start, end []byte) types.Iterator

Implements types.KVStore.

func (*Store) LastCommitID 

func (st *Store) LastCommitID() types.CommitID

Implements Committer.

func (*Store) LastCommitVersion added in v1.6.3 

func (st *Store) LastCommitVersion() int64

func (*Store) Query 

func (st *Store) Query(req abci.RequestQuery) (res abci.ResponseQuery)

Query implements ABCI interface, allows queries

by default we will return from (latest height -1), as we will have merkle proofs immediately (header height = data height + 1) If latest-1 is not present, use latest (which must be present) if you care to have the latest data to see a tx results, you must explicitly set the height you want to see

func (*Store) ResetCount 

func (st *Store) ResetCount()

func (*Store) ReverseIterator 

func (st *Store) ReverseIterator(start, end []byte) types.Iterator

Implements types.KVStore.

func (*Store) Set 

func (st *Store) Set(key, value []byte)

Implements types.KVStore.

func (*Store) SetInitialVersion 

func (st *Store) SetInitialVersion(version int64)

SetInitialVersion sets the initial version of the IAVL tree. It is used when starting a new chain at an arbitrary height.

func (*Store) SetPruning 

func (st *Store) SetPruning(_ types.PruningOptions)

SetPruning panics as pruning options should be provided at initialization since IAVl accepts pruning options directly.

func (*Store) SetUpgradeVersion added in v1.3.0 

func (st *Store) SetUpgradeVersion(version int64)

func (*Store) StartTiming added in v1.6.7 

func (st *Store) StartTiming()

func (*Store) StopStore 

func (st *Store) StopStore()

func (*Store) StopStoreWithVersion added in v1.6.1

func (st *Store) ValidateFlatVersion() error

func (*Store) VersionExists 

func (st *Store) VersionExists(version int64) bool

VersionExists returns whether or not a given version is stored.

type Tree 

type Tree interface {
	Has(key []byte) bool
	Get(key []byte) (value []byte)
	Set(key, value []byte) bool
	Remove(key []byte) ([]byte, bool)
	PreChanges(keys []string, setOrDel []byte)
	SaveVersion(bool) ([]byte, int64, iavl.TreeDelta, error)
	GetModuleName() string
	GetDBWriteCount() int
	GetDBReadCount() int
	GetDBReadTime() int
	GetNodeReadCount() int
	ResetCount()
	DeleteVersion(version int64) error
	DeleteVersions(versions ...int64) error
	Version() int64
	Hash() []byte
	VersionExists(version int64) bool
	GetVersioned(key []byte, version int64) (int64, []byte)
	GetVersionedWithProof(key []byte, version int64) ([]byte, *iavl.RangeProof, error)
	GetImmutable(version int64) (*iavl.ImmutableTree, error)
	SetInitialVersion(version uint64)
	SetDelta(delta *iavl.TreeDelta)
	GetPersistedRoots() map[int64][]byte
	SetUpgradeVersion(int64)
}

Tree defines an interface that both mutable and immutable IAVL trees must implement. For mutable IAVL trees, the interface is directly implemented by an iavl.MutableTree. For an immutable IAVL tree, a wrapper must be made.
