Dynamic structure (Variable type) In french: Structure dynamique (Type de variable)
A structure can be allocated dynamically: we talk of dynamic instantiation of the structure. The dynamic instantiation of structure is used to create a structure at a given time and to free this structure when it is no longer used. To instantiate a structure, you must: - Declare a dynamic structure.
- Instantiate a structure.
Remark: The structure is automatically freed when it is not used anymore. However, you can force the destruction of the structure. MyExampleFile is Structure
Name is string
Extension is string
Directory is string
END
SourceFile is dynamic MyExampleFile
// ...
SourceFile = new MyExampleFile
// Process on the object ...
// ...
// Free the object
delete SourceFile
MyClass is Class
sMB is string
END
MyExampleFile is Structure
Name is string
Extension is string
Directory is string
END
ArraySourceFile is array * dynamic MyClass.MyExampleFile
