Example Dictionary ref 009

 

 

Description

This example shows the ref function returns the key or value of the Dictionary through the index reference. This example uses the (ref aDictionary index1 index2) function syntax.

 

Details

(define aDictionary #{dic| Name: "Bill" SSN: "616 55 1209" Age: 45} ) Returns: #<Dictionary 123456>

The ref function returns key of the Dictionary with the specified indices.

(ref aDictionary 0 0) Returns: Age:

The ref function returns the values of the Dictionary with the specified indices.

(ref aDictionary 0 1) Returns: 45

The ref function returns key of the Dictionary with the specified indices.

(ref aDictionary 1 0) Returns: Name:

The ref function returns the values of the Dictionary with the specified indices.

(ref aDictionary 0 1) Returns: 45

Other values and keys of the Dictionary with the specified indices.

(ref aDictionary 1 1) Returns: Bill
(ref aDictionary 2 0) Returns: SSN
(ref aDictionary 2 1) Returns: 616 55 1209

Notes and Hints

An often used shorthand to reference a dictionary value or key is the . (period) operator or the [ ] (bracket) operator.

(define Dict #{dic| Name: "Bill" SSN: "616 55 1209" Age: 45} )

Dict.Age or Dict[0] Returns:45
Dict.Name or Dict[1] Returns:Bill
Dict.SSN or Dict[2] Returns:616 55 1209

When a single index is used, the value portion of the specified binding is returned. However two indices offer the flexibility of referencing either the key or value.

(define Dict #{dic| Name: "Bill" SSN: "616 55 1209" Age: 45} )

Dict[0 0] Returns:Age
Dict[0 1] Returns:45
Dict[1 0] Returns:Name
Dict[1 1] Returns:Bill
Dict[2 0] Returns:SSN
Dict[2 1] Returns:616 55 1209
