valid

Class: coder.dictionary.Entry
Package: coder.dictionary

Determine if coder.dictionary.Entry object represents a valid code definition

Syntax

tf = valid(entryObj)


Description

tf = valid(entryObj) returns true if the coder.dictionary.Entry object entryObj is valid. A coder.dictionary.Entry object is valid if it represents an existing code definition. When you remove the code definition that the entry represents, the coder.dictionary.Entry object is not valid.

Input Arguments

entryObj — Embedded Coder Dictionary entry

coder.dictionary.Entry object

Embedded Coder Dictionary entry, specified as a coder.dictionary.Entry 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 Entry Object Is Valid

Open the model rtwdemo_roll and represent the Embedded Coder Dictionary by using a coder.Dictionary object. Use this object to access the Storage Classes section of the dictionary and represent the section by using a coder.dictionary.Section object.

rtwdemo_roll
coderDictionary = coder.dictionary.open('rtwdemo_roll');
storageClassesSect = getSection(coderDictionary, 'StorageClasses');

Represent the example storage class ParamStruct by using a coder.dictionary.Entry object.

entryObj = getEntry(storageClassesSect,'ParamStruct');

Check if the coder.dictionary.Entry object in the base workspace represents a valid code definition.

valid(entryObj)

ans =

  logical

   1

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

deleteEntry(storageClassesSect,'ParamStruct');
valid(entryObj)

ans =

  logical
