AttributeGetDouble Function

Action

Retrieves a floating-point value from a specified attribute of the user.

User attributes are useful when working with Silk Performer frameworks, in fact, when the user behavior is defined in two separate script. In that case, user attributes enable the exchange of data between scripts, for example, between a Silk Performer and a Java script.

Another useful scenario is to define project attributes in Silk Performer. Using AttributeGet(Bool, Double, Int, String), these values can be retrieved by the BDL script in order to parameterize the script via project attributes.

    sUrl, sString, sBuffer : string;
  begin
    AttributeSetString("name", "Jim");
    AttributeSetInt("age", 23);
    AttributeSetDouble("cash", 4503.60);
    AttributeSetBinary("code", "\h9EF30533", 4);
  
    // do anything, for example, call an external function
    for i := 1 to AttributeGetInt("TIMES") do
      AttributeGetString("URL", sUrl);
      WebPageUrl(sUrl);
    end;

    AttributeGetString("name", sString);
    writeln(sString);
    writeln(AttributeGetInt("age"));
    writeln(AttributeGetDouble("cash"));
    AttributeGetBinary("code", sBuffer);
    WriteData(sBuffer, STRING_COMPLETE);
  end TMain;
