Valid for: CANoe DE

Function Syntax

long DiagGetPrimitiveSize( diagRequest request);
long DiagGetPrimitiveSize( diagResponse response);

Method Syntax

Method Syntax

diagRequest::GetPrimitiveSize();
diagResponse::GetPrimitiveSize();

Description

Returns the byte length of the object.

Parameters

• request: Request
• response: Response

Return Values

• > 0: Number of bytes.
• < 0: Error code

Example

The following example shows how to retrieve parameter values via symbolic access while using an universal “on diagRequest” handler (”*”).

// e.g. used in a Tester module
on diagResponse *
{
  byte data[4096];
  long size;
  double param_value1=0xFF;
  double param_value2=0xFF;
  diagResponse * resp; // declare response with no concrete interpretation

  size=this.GetPrimitiveSize(); // get length of response
  this.GetPrimitiveData(data, elcount(data)); // copy actual response from "on diagResponse *" into data array

  switch(data[0]) 
  {
    case 0x50: // UDS: DiagnosticSessionControl_Process positive Response
      diagInitialize(resp, "DiagnosticSessionControl_Process");
      resp.Resize(size); // make sure there is room for the received bytes
      resp.SetPrimitiveData(data, size); // initialize resp with actual response from data array
      param_value1=diagGetParameter(resp, "diagnosticSessionType");
      param_value2=diagGetParameter(resp, "sessionParameterRecord");
      break;
    case 0x51: // UDS: EcuReset_Process positive Response
      diagInitialize(resp, "EcuReset_Process");
      resp.Resize(size); // make sure there is room for the received bytes
      resp.SetPrimitiveData(data, size); // initialize resp with actual response from data array
      param_value1=diagGetParameter(resp, "resetType");
      param_value2=diagGetParameter(resp, "powerDownTime");
      break;
    default:
      break;
  }
  write("Tester: Value of parameter according to chosen interpretation: 0x%x 0x%x %3.0lf %3.0lf",data[0], data[1], param_value1, param_value2);
}
