  • Method Details

    • getBlockByHash

      public void getBlockByHash(QueryProto.GetBlockByHashRequest request, io.grpc.stub.StreamObserver<QueryProto.GetBlockByHashResponse> responseObserver)
      
 Get a block identified by its hash
 查询哈希所指定的区块

    • getBlocks

      public void getBlocks(QueryProto.BlocksRequest request, io.grpc.stub.StreamObserver<QueryProto.GetBlocksResponse> responseObserver)
      
 Get blocks in a timestamp range
 查询时间范围内的区块
 Requirement: start_timestamp <= end_timestamp
 If neither 'start_timestamp' nor 'end_timestamp' is specified, then 'start_timestamp' will be set to
 the genesis block's timestamp, and 'end_timestamp' will be set to (start_timestamp + query.maxDuration)
 (query.maxDuration is specified in go-bdledger's config file).
 If only 'end_timestamp' is not specified, or (end_timestamp - start_timestamp > query.maxDuration),
 then 'end_timestamp' will be set to (start_timestamp + query.maxDuration).
 If only 'start_timestamp' is not specified, then 'start_timestamp' will be set to (end_timestamp - query.maxDuration).
 In all cases, 'start_timestamp' will never be earlier than the genesis block's timestamp,
 and 'end_timestamp' will never be later than the current timestamp when the node process the query request.

    • countBlocks

      public void countBlocks(QueryProto.BlocksRequest request, io.grpc.stub.StreamObserver<QueryProto.CountBlocksResponse> responseObserver)
      
 Count all blocks in a ledger, or blocks in a timestamp range
 查询帐本中的所有区块数量，或时间范围内的区块数量
 Requirement: start_timestamp <= end_timestamp
 If neither 'start_timestamp' nor 'end_timestamp' is specified, then count all blocks in the specified ledger.
 If only 'end_timestamp' is not specified, then count all blocks with timestamps later than 'start_timestamp'.
 If only 'start_timestamp' is not specified, then count all blocks with timestamps earlier than 'end_timestamp'.
 In all cases, 'start_timestamp' will never be earlier than the genesis block's timestamp,
 and 'end_timestamp' will never be later than the current timestamp when the node process the query request.

    • getRecentBlocks

      public void getRecentBlocks(QueryProto.RecentBlocksRequest request, io.grpc.stub.StreamObserver<QueryProto.GetBlocksResponse> responseObserver)
      
 Get recent 'count' blocks (Only support IncludeTransactions=NONE for now)
 查询最新的 'count' 个区块

    • getTransactionByHash

      public void getTransactionByHash(QueryProto.GetTransactionByHashRequest request, io.grpc.stub.StreamObserver<QueryProto.GetTransactionByHashResponse> responseObserver)
      
 Get a transaction identified by its hash
 查询哈希所指定的事务

    • getTransactionByBlockHashAndIndex

      public void getTransactionByBlockHashAndIndex(QueryProto.GetTransactionByBlockHashAndIndexRequest request, io.grpc.stub.StreamObserver<QueryProto.GetTransactionByBlockHashAndIndexResponse> responseObserver)
      
 Get a transaction identified by hash of the block it belongs to and its index inside the block
 查询所在区块的哈希与其在区块中的index所指定的事务

    • getTransactions

      public void getTransactions(QueryProto.TransactionsRequest request, io.grpc.stub.StreamObserver<QueryProto.GetTransactionsResponse> responseObserver)
      
 Get transactions in a timestamp range
 查询时间范围内的事务
 'start_timestamp' and 'end_timestamp' follow the same requirements and rules as in 'GetBlocks'.

    • countTransactions

      public void countTransactions(QueryProto.TransactionsRequest request, io.grpc.stub.StreamObserver<QueryProto.CountTransactionsResponse> responseObserver)
      
 Count all transactions in a ledger, or transactions in a timestamp range
 查询帐本中的所有事务数量，或时间范围内的事务数量
 'start_timestamp' and 'end_timestamp' follow the same requirements and rules as in 'CountBlocks'.

    • bindService
