Determine if data element is defined in generated code

R2025a 以降

構文

tf = isDefined(implementation)


説明

tf = isDefined(implementation) returns 1 (true) if the data element is defined by the generated code. Otherwise, it returns 0 (false).

The data element is defined if all members of the TypedRegion object exist in the generated code.

入力引数

implementation — Description of implementation of data

coder.descriptor.TypedRegion object

Description of implementation of data in the generated code, specified as a coder.descriptor.TypedRegion object.

Output Arguments

tf — True or false result

1 | 0

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

データ型: logical

例

Determine if Inport Block Is Defined by Generated Code

1. Open the model.

   openExample('CustomCodeComments')

2. Build the model.

   slbuild('CustomCodeComments')

3. Create a coder.codedescriptor.CodeDescriptor object for the required model.

   codeDescObj = coder.getCodeDescriptor('CustomCodeComments')
   

4. Return properties of the Inports data interface type in the generated code.

   dataInterfaces = getDataInterfaces(codeDescObj, 'Inports')

5. Return properties of the code representation of the first Inport block.

   implementation = dataInterfaces(1).Implementation

6. Return whether the data element is defined by its code representation.

   isDefined(implementation)

   ans =
     logical
      1

   Since isDefined returned logical 1, all members of implementation exist in the generated code.
