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

Flag to throw an error if the expression is not usable in arbitrary code. The elements of the expression are usable if all members of the TypedRegion object exist in the generated code and are not private or protected class members.

  • false or 0 — Throw an error.

  • true or 1 — Do not throw an error.

データ型: logical

C/C++ expression to access the address of the data element in the generated code, relative to the topmost element in the TypedRegion object, returned as a character vector.

データ型: char

例

  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 the C expression for accessing the address of the first Inport block in the generated code.

    getAddress(implementation)
    ans =
    '&(rtU.In1)'
