You can use JSL classes to create objects, providing definitions for member variables, methods, and functions. The JSL function Define Class() has a number of arguments that define the contents of the class:
|
•
|
"class name" is the name of the class being defined.
|
|
•
|
"base class name" are one or more class names that make the set of base classes that are used as the foundation of the class being created.
|
|
•
|
namespace defines a specific namespace that stores unscoped variables defined in methods and functions.
|
|
•
|
Show defines the value that appears when a class object is written out using the Show(), Print(), or Write() functions. Options include:
|
|
‒
|
All (Boolean) shows all members, methods, and functions defined in a class object instance. The default value for All is true.
|
|
‒
|
Members (Boolean) shows all member variables contained in a class object instance.
|
|
‒
|
Methods (Boolean) shows all methods contained in a class object instance.
|
|
‒
|
Functions (Boolean) shows all functions contained in a class object instance.
|
注意：You can specify either the All option or any number of the Members, Methods, and Functions options, but you cannot specify both options at the same time.
注意：Statements can be separated by either a comma or semicolon, but must be done consistently within the Define Class() function.

To override what contents should be shown, a class object is displayed using the Show(), Print(), or Write() function and defining a show Method() that returns a value to be used.

In cases when a string representation is needed, such as a Char() function or concatenation operator, define a To String method that will return a string result to be used.
