Example Function addMethod 017

 

 

Description

This example defines a method named evalFun that is invoked when the Function type receives a eval message. The evalFun method takes function with a single parameter, coerces the parameter to an integer and returns the result after evaluating the function.

 

Details

First Define the evalFun method:

(defun evalFun (fname arg) (fname (integer arg)) ) Returns: #<Lambda 123456>

Install the evalFun method and the message named eval in the Function Methods Dictionary.

(addMethod Function: eval: evalFun) Returns: #<Dictionary 123456>

To invoke the Lambda that responds to the eval message, issue the following statement:

(send eval: add1 96.1 ) Returns: 97

Alternatively, the Lambda may be invoked using the following syntax:

(eval: add1 96.1 ) Returns: 97
