NAME

esi::Argv -

Simplest string container interface, ala C's argv.

SYNOPSIS

#include <ArgvInterface.h>

Detailed Description

Simplest string container interface, ala C's argv.

A little iterator interface interface around arrays of strings, whereever tbey may be fetched from an ESI interface. In particular: Exists because we want a simple, abstract alternative to the STL. Implementors are free to use the STL underneath this interface if they so choose.

    An example of its use:


    SomeConcreteArgvImpl argvimpl;
	// perhaps the argv class from the reference implementation.


    esi::Argv *argvi = dynamic_cast<esi::Argv *>(&argvimpl);


    esi_int err;


    err = object->getRunTimeModels(argvi, char *msg);


    if (!err) {


   	        const char *arg;


   		      for (i = 0; (arg = argvi->get(i)) != 0; i++) {


   			              do.something(arg);


   				            }


   		        delete argvi;


     }


     argvi = 0;


     And inside the getRunTimeModels call, a set of calls on


     	argvi->appendArg(rtmodelName[i]);


     occurs, filling in the answers.


   

This pattern keeps creation/management of all the memory associated with the Argv in the scope of the caller or internal to the Argv itself.
