Re: Calling multi functions in a single statement

So will $logviewer->get_log_records()->XML_file(); just call both the functions

The first method is being called on an object instance of type CCI::LogViewer, and once it has returned, the second method will be called on whatever object has been returned by the first method (could be an object of a different type (i.e. I haven't checked what it returns)).

That sounds good. But from what you said I believe that there should be more than one `XML_file` subroutine so that once an object is returned by `get_log_records()` it could decide on which Package it should call `XML_file()`. Now if that is true, I found that the subroutine `XML_file` is only in one package and not in any other. So does that make any sense in executing `$logviewer->get_log_records()->XML_file();`. It could have rather just been written as `$logviewer->get_log_records(); $logviewer->XML_file();` [download]	[reply] [d/l] [select]

Just because XML_file is in the same class as get_log_records doesn't mean the two statements are equivalent. Perhaps they are. But that depends on what get_log_records returns. And it only depends on what get_log_records returns.	[reply]
