Writing a Slice Definition
The first step in writing any Ice application is to write a Slice definition containing the interfaces that are used by the application. For our minimal printing application, we write the following Slice definition:
Slice
module Demo { interface Printer { void printString(string s); }; };
We save this text in a file called Printer.ice
.
Our Slice definitions consist of the module Demo
containing a single interface called Printer
. For now, the interface is very simple and provides only a single operation, called printString
. The printString
operation accepts a string as its sole input parameter; the text of that string is what appears on the (possibly remote) printer.
