Open the model RollAxisAutopilot 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.

openExample('RollAxisAutopilot')
coderDictionary = coder.dictionary.open('RollAxisAutopilot');
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

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 =
