write method

void write(String? correlationId, String? component, String? operation, Exception? error, int duration,)

Writes a log message to the logger destination.

• correlationId (optional) transaction id to trace execution through call chain.
• component a name of called component
• operation a name of the executed operation.
• error an error object associated with this trace.
• duration execution duration in milliseconds.

Implementation

void write(String? correlationId, String? component, String? operation,
    Exception? error, int duration) {
  var errorDesc =
      error != null ? ErrorDescriptionFactory.create(error) : null;

  /// Account for cases when component and operation are combined in component.
  if (operation == null || operation == '') {
    if (component != null && component != '') {
      var pos = component.lastIndexOf('.');
      if (pos > 0) {
        operation = component.substring(pos + 1);
        component = component.substring(0, pos);
      }
    }
  }

  var trace = OperationTrace(DateTime.now(), _source, component, operation,
      correlationId, duration, errorDesc);

  _cache.add(trace);
  update();
