New custom types can be created as:
Classes and arrays have some commonalities:
The compiler handles classes and arrays as custom types, and both have standard functions accessible in an x.y format. The many standard functions are described in detail on their respective pages - e.g. with the Class.New and Array.New as the most noticeable.
Classes and arrays provide the means for creating powerful source code programming. Here is an appetizer:
//We create 2 classes TFile and TDirectory to contain a tree of folders and files.
//NB! Using the T prefix on class names is a matter of taste. Do it as you please.
Public String Name;
Public Integer Size;
Public Datetime LastModified;
Public String Path; //Current folder.
Public TDirectory Directories; //Array of child folders.
Public TFile Files; //Array of child files.
Public Function Initialize()
Directories.New(); //Instantiate the
Files.New(); //two arrays.
Public Function AddDirectory(String dirPath) : Integer
directory.Path := dirPath;
Public Function AddFile(String name; Integer size; Datetime lastModified) : Integer
TFile file.New().Name := name;
file.Size := size;
file.LastModified := lastModified;
If this example raises some questions - don't worry - the next chapters describe the details of the class and array types.
