parseDataNode static method

Node? parseDataNode(List<int>? response, Seed seedActive)

Parses the network response to extract Node information based on the provided active seed.

This method takes a response, which is a list of integers representing the raw data received from the network, and a seedActive, which is the active seed associated with the Node. It returns a Node object if the parsing is successful, otherwise returns null.

The response is expected to contain space-separated values, and the method attempts to extract relevant information to construct a Node object. If the response is null or does not contain enough values, the method returns null.

Input:

• response: List of integers representing the raw data received from the network.
• seedActive: The active seed associated with the Node.

Output:

• Node A constructed Node object if parsing is successful, otherwise null.

Example Usage:

List<int> response = ... // Raw network response as a list of integers.
Seed activeSeed = ...    // Active seed associated with the Node.
Node? parsedNode = NodeParser.parseResponseNode(response, activeSeed);

Note: The method uses try-catch to handle potential exceptions during parsing, returning null in case of an error.

Implementation

static Node? parseDataNode(List<int>? response, Seed seedActive) {
  if (response == null) {
    return null;
  }
  try {
    List<String> values = String.fromCharCodes(response).split(" ");

    if (values.length <= 2) {
      return null;
    }

    return Node(
      seed: seedActive,
      connections: int.tryParse(values[1]) ?? 0,
      lastblock: int.tryParse(values[2]) ?? 0,
      pendings: int.tryParse(values[3]) ?? 0,
      delta: int.tryParse(values[4]) ?? 0,
      branch: values[5],
      version: values[6],
      utcTime: int.tryParse(values[7]) ?? 0,
      lastblockhash: values[10].substring(0, 5),
      headershash: values[15],
      sumaryhash: values[17],
    );
  } catch (e) {
    return null;
  }
