Types

type TxIndex

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

    TxIndex is the simplest possible indexer, backed by key-value storage (levelDB).

    func NewTxIndex

    func NewTxIndex(store dbm.DB) *TxIndex

      NewTxIndex creates new KV indexer.

      func (*TxIndex) AddBatch

      func (txi *TxIndex) AddBatch(b *txindex.Batch) error

        AddBatch indexes a batch of transactions using the given list of events. Each key that indexed from the tx's events is a composite of the event type and the respective attribute's key delimited by a "." (eg. "account.number"). Any event with an empty type is not indexed.

        func (*TxIndex) Get

        func (txi *TxIndex) Get(hash []byte) (*abci.TxResult, error)

          Get gets transaction from the TxIndex storage and returns it or nil if the transaction is not found.

          func (*TxIndex) Index

          func (txi *TxIndex) Index(result *abci.TxResult) error

            Index indexes a single transaction using the given list of events. Each key that indexed from the tx's events is a composite of the event type and the respective attribute's key delimited by a "." (eg. "account.number"). Any event with an empty type is not indexed.

            func (*TxIndex) Search

            func (txi *TxIndex) Search(ctx context.Context, q *query.Query) ([]*abci.TxResult, error)

              Search performs a search using the given query.

              It breaks the query into conditions (like "tx.height > 5"). For each condition, it queries the DB index. One special use cases here: (1) if "tx.hash" is found, it returns tx result for it (2) for range queries it is better for the client to provide both lower and upper bounds, so we are not performing a full scan. Results from querying indexes are then intersected and returned to the caller, in no particular order.

              Search will exit early and return any result fetched so far, when a message is received on the context chan.
