type TraceKVStore

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

TraceKVStore implements the KVStore interface with tracing enabled. Operations are traced on each core KVStore call and written to the underlying io.writer.

TODO: Should we use a buffered writer and implement Commit on TraceKVStore?

func NewTraceKVStore

func NewTraceKVStore(parent sdk.KVStore, writer io.Writer, tc TraceContext) *TraceKVStore

NewTraceKVStore returns a reference to a new traceKVStore given a parent KVStore implementation and a buffered writer.

func (*TraceKVStore) CacheWrap

func (tkv *TraceKVStore) CacheWrap() sdk.CacheWrap

CacheWrap implements the KVStore interface. It panics as a TraceKVStore cannot be cache wrapped.

func (*TraceKVStore) CacheWrapWithTrace

func (tkv *TraceKVStore) CacheWrapWithTrace(_ io.Writer, _ TraceContext) CacheWrap

CacheWrapWithTrace implements the KVStore interface. It panics as a TraceKVStore cannot be cache wrapped.

func (*TraceKVStore) Delete

func (tkv *TraceKVStore) Delete(key []byte)

Delete implements the KVStore interface. It traces a write operation and delegates the Delete call to the parent KVStore.

func (*TraceKVStore) Get

func (tkv *TraceKVStore) Get(key []byte) []byte

Get implements the KVStore interface. It traces a read operation and delegates a Get call to the parent KVStore.

func (*TraceKVStore) GetStoreType

func (tkv *TraceKVStore) GetStoreType() sdk.StoreType

GetStoreType implements the KVStore interface. It returns the underlying KVStore type.

func (*TraceKVStore) Has

func (tkv *TraceKVStore) Has(key []byte) bool

Has implements the KVStore interface. It delegates the Has call to the parent KVStore.

func (*TraceKVStore) Iterator

func (tkv *TraceKVStore) Iterator(start, end []byte) sdk.Iterator

Iterator implements the KVStore interface. It delegates the Iterator call the to the parent KVStore.

func (*TraceKVStore) Prefix

func (tkv *TraceKVStore) Prefix(prefix []byte) KVStore

Prefix implements the KVStore interface.

func (*TraceKVStore) ReverseIterator

func (tkv *TraceKVStore) ReverseIterator(start, end []byte) sdk.Iterator

ReverseIterator implements the KVStore interface. It delegates the ReverseIterator call the to the parent KVStore.

func (*TraceKVStore) Set

func (tkv *TraceKVStore) Set(key []byte, value []byte)

Set implements the KVStore interface. It traces a write operation and delegates the Set call to the parent KVStore.
