An IDL constant is mapped to a Python variable with an equivalent name and scope. The Python variable is initialised with the value of the constant. Of course, Python does not have real `constants', and nothing actually stops you assigning to these variables, but doing so is obviously not recommended.
e.g. consider the following IDL:
#pragma prefix "dstc.edu.au"
//
// Constant example.
//
module Example {
const long MAX_LENGTH = 999;
const string NAME = "Martin Chilvers";
interface Foo {
const float PI = 3.14;
};
};
The constants can be used in Python as follows:
>>> import Example >>> Example.MAX_LENGTH 999 >>> Example.NAME `Martin Chilvers' >>> Example.Foo.PI 3.14 >>>
