# Example Matrix send 008

#### Description

This example first defines the method addValues. It then invokes the addMethod function to add the method in the Methods Dictionary. The method addValues will be then invoked by the send function calling the message in the Matrix Methods Dictionary.

#### Details

Add a method named addValues which will add the values of all the fields in a Matrix.

 (addMethod Matrix: addValues: (lambda (s) (apply + s))) Returns: #

Define a Matrix that contains the amount of checks written for the month.

 (define monthlyBills #(mat| 400 2100 100 600) ) Returns: #

Invoke the method named addValues to compute the total amount checks written for the month.

 (send addValues: monthlyBills) Returns: 3200

The method can be invoked simply by name:

 (addValues: monthlyBills) Returns: 3200

Notes and Hints

Dissecting the send command involves understanding the methods dictionary of any Analytic Information Server type. In general the send command is translated as a reference into the methods dictionary:

((ref (methodsOf (type object)) methodName object))

The statement :

(send addValues: monthlyBills)

is translated into

((ref (methodsOf (type monthlyBills)) addValues: ) monthlyBills)

Each statement segment results in:

 (type monthlyBills) Returns: Vector (methodsOf (Matrix:)) Returns: # (ref (#) addValues: ) Returns: # ( # monthlyBills) Returns: 3200
