Example BitVector send 018

 

 

Description

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

 

Details

Add a method named addBits which will add the values of all the fields in a Vector.

(addMethod BitVector: addBits: (lambda (s) (apply + s))) Returns: #<Dictionary 123456>
(define Bits #(bit| 1 1 0 0 1 1 1) ) Returns: #<BitVector 123456>

Invoke the method named addBits to compute the number of bits in the BitVector.

(send addBits: Bits) Returns: 5

The method can be invoked simply by name:

(addBits: Bits) 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 addBits: Bits)

is translated into

((ref (methodsOf (type Bits)) addBits: ) Bits)

Each statement segment results in:

(type Bits) Returns: BitVector
(methodsOf (BitVector:)) Returns: #<Dictionary 123456>
(ref (#<Dictionary 123456>) addBits: ) Returns: #<Lambda 123456>
( #<Lambda 123456> Bits) Returns: 3200
