valid

Class: coder.Dictionary
Namespace: coder

Determine whether coder.Dictionary object represents a valid Embedded Coder Dictionary

Since R2019b

Syntax

tf = valid(coderDictionaryObj)


Description

tf = valid(coderDictionaryObj) returns true if the coder.Dictionary object coderDictionaryObj is valid. A coder.Dictionary object is valid if it represents an existing Embedded Coder Dictionary. When you remove the Embedded Coder Dictionary, the coder.Dictionary object is not valid.

Input Arguments

coderDictionaryObj — Embedded Coder Dictionary object

coder.Dictionary object

Embedded Coder Dictionary, specified as a coder.Dictionary object.

Output Arguments

tf — True or false result

1 | 0 | logical array

True or false result, returned as a 1 or 0 of data type logical.

Examples

Check If Embedded Coder Dictionary Object Is Valid

Create a data dictionary named 'dataDict.sldd' in the base workspace and create an Embedded Coder Dictionary in the data dictionary. Represent the Embedded Coder Dictionary by using the coder.Dictionary object myCoderDictObj in the base workspace.

Simulink.data.dictionary.create('dataDict.sldd');
myCoderDictObj = coder.dictionary.create('dataDict.sldd');

Check whether the coder.Dictionary object in the base workspace represents a valid Embedded Coder Dictionary.

valid(myCoderDictObj)

ans =

  logical

   1

Remove the Embedded Coder Dictionary from the data dictionary and check the coder.Dictionary object again. When you remove the Embedded Coder Dictionary, the coder.Dictionary object is not valid.

coder.dictionary.remove('dataDict.sldd');
valid(myCoderDictObj)

ans =

  logical

   0
