Visual Programming II (Advanced)
This section describes the following advanced programming concepts and tools :
-
defining options or control procedures within programs,
-
designing complex programming structures by the means of functional abstraction[1] or iteration[2],
-
manipulating and globalizing objects with instances[3] and global variables[4],
-
using files and advanced user inetraction modules.
References :
- Functional Abstraction
A functional abstraction is a program whose some elements can become variables, via connections to the outside environment. Hence, this program must have inputs or outputs that can be connected to external variable elements. The resulting functional abstraction can then be embedded into other programs to be used as a functional component.
- Iteration
The repetition of a process within a computer program.
See also : Recursion.
- Instance
An actual object created at runtime, out of a given class. In OM, more specifically, an object created when evaluating a factory box. An instance can be saved as a global variable.
⤷ SHIFT click on an outlet - especially the first outlet representing the
self, the whole object - of a factory box to materialize an instance.
- Global variable
An instance of OM object that has been saved in order to be used in other
programs. Global variables are visible from the Library window and stored as
.omi files in the Globals folder of the workspace.
