Overview

The addMethod function associates a method {proc} to the specified type {type} that responds to a nessage {msgName}. This function is instrumental in providing Analytic Information Server with support for standard Object Oriented Programming features. After the addMethod associates a method {methodName} with the specified type {type}, the {methodName} can be used as if it was a native Analytic Information Server function for a that type.

The Analytic Information Server Lisp compiler constructs a method binding from the {methodName} argument and the Lambda object defined in the argument {proc}. The new method binding is installed in the methods Dictionary associated with the specified type {type}. In summary, the defmethod creates a new method binding for a type (can be any Analytic Information Server type or user defined type) . The addmethod function returns the Methods Dictionary object.

Methods Dictionary

MsgName1	LambdaName1
MsgName2	LambdaName2
MsgName3	LambdaName3

Usage

Use the addMethod function to define a method (Lambda) that operates differently on Strings than it does on other types. This allows the standard type polymorphism of standard Object Oriented Programming (OOP). Analytic Information Server supports both standard OOP type polymorphism and Lambda polymorphism.
