How do I Create a Method with more than 1 argumnent? (error compiling).

Submitted by Alexandrenagy on Fri, 2010-07-30 17:07

Hello guys.

I am having problems creating a method with more than one arguments. The problem, I guess, is on the constructor of the code. The following code works well good.

source.h === ... Method<bool(double)> sendVoltageRTT; bool sendVoltage(double bit); ... ===

source.c === source::source(string name): TaskContext(name), sendVoltageRTT("sendVoltage", &source::sendVoltage,this) {
    this->methods()->addMethod(&sendVoltageRTT, "send Voltage.","bit","bit value in 0-4095");
}

... ===

This method has only one argument as the examples at the manual show. In the manual, it is written that I could create methods with more than one argument. The following code do not work.

source.h === ... Method<bool(double)> sendVoltageRTT; bool sendVoltage(double bit);

Method<bool(double,int) readVoltageRTT; bool readVoltage(int subdevice, int channel); ... ===

source.c === ... source::source(string name): TaskContext(name), sendVoltageRTT("sendVoltage", &source::sendVoltage,this), readVoltageRTT("readVoltage", &source::readVoltage, this) {

this->methods()->addMethod(&sendVoltageRTT, "send Voltage.","bit","bit value in 0-4095");

this->methods()->addMethod(&readVoltageRTT, "read voltage a channel at a subdevice","subdevice","subdevice number","channel", "channel number"); }

... ===

The error is on the last commando, on addMethod. I don't know how many paramaeters I need to put at the commando.

Anybody already used a Method with more than one argument? What is the sintax?

Best Regards. Alexandre.

The problem is here: you should have written:

Method<bool(int,int)> readVoltageRTT;

so replace the double with the int.

You can escape from such typo errors by using the method() helper
function. Then you can omit the Method<> line and directly write in
your constructor:

this->methods()->addMethod(
method("readVoltage",&source::readVoltage,this) , "read voltage a
channel at a subdevice","subdevice","subdevice number","channel",
"channel number");

The one that wants to call the method still needs to use the Method<>
helper, there's no way around that one.
