J methods

Definition

J methods support the definition of all J program processing. They are linked to J classes.

Declaration

A J method called "method_name", linked to a J class called "class_name", in the default UML profile, will be defined as follows:

class_name: default#method_name

{

// J instructions

}

Note: The metamodel editor produces this syntax, and the J programmer need only enter the instructions that make up the method body.

Example

We are going to write a specific "print" method, linked to the "Class" class and that displays the class name.

Class:print()

{

// the name of a class is contained in the Name attribute

StdOut.write("PRINT ", Name);

}
