    Syntax

    setDataDefault(myCodeMappingObj,category,Name,Value)

    Description

    example

    setDataDefault(myCodeMappingObj,category,Name,Value) sets the default storage class and storage class property values in the code mappings for the specified category of model data.

    Examples

    In the model code mappings for model myConfigModel, configure the default representation of model workspace parameters in generated code as unstructured global variables by setting the default storage class to ExportedGlobal.

    cm = coder.mapping.api.get('myConfigModel');
setDataDefault(cm,'ModelParameters','StorageClass','ExportedGlobal');

    In the model code mappings for model myConfigModel, configure the code generator to write root-level outport data to separate global variables declared and defined in external files myextheader.h and myextsrc.c. 

    cm = coder.mapping.api.get('myConfigModel');
setDataDefault(cm,'Outports','StorageClass','ExportToFile',...
  'HeaderFile',myextheader.h','DefinitionFile','myextsrc.c');

    Input Arguments

    collapse all

    Code mapping object (model code mappings) returned by a call to function coder.mapping.api.get.

    Example: myCM

    Category of model data element for which to set the storage class and storage class properties.

    Example: 'Inports'

    Name-Value Pair Arguments

    Example: 'StorageClass','ExportedGlobal'

    Specify comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments as Name1,Value1,…,NameN,ValueN. The order of the name and value pair arguments does not matter.

    Storage class to set for the specified data element category. The name of a predefined storage class or storage class that is defined in the Embedded Coder Dictionary associated with the model. Values that you can specify vary depending on the category that you specify. See Choose Storage Class for Controlling Data Representation in Generated Code.

    Example: 'StorageClass','ImportedExtern'

    File name for a C source file that contains definitions for global data read by data elements and external code. Applies to storage classes Const, ConstVolatile, ExportToFile, and Volatile.

    Example: 'DefinitionFile','myDataDefs.c'

    Data Types: char | string

    Name of a get function that a data element calls in the generated code. Applies to storage class GetSet.

    Example: 'GefFunction','myDataGetFunction'

    Data Types: char | string

    File name for a C header file that contains declarations for global data read by data elements and external code. Applies to storage classes Const, ConstVolatile, Define, ExportToFile, GetSet, ImportedDefine, ImportFromFile, and Volatile.

    Example: 'HeaderFile','myDataDecl.h'

    Data Types: char | string

    Name of a memory section that is defined in the Embedded Coder Dictionary associated with the model.

    Example: 'MemorySection','myFastMem'

    Data Types: char | string

    Name of the model that owns global data, which is used by other models in the same model hierarchy. The code generated for the model that owns the data includes the global data definition. Applies to storage classes Const, ConstVolatile, ExportToFile, and Volatile.

    Example: 'Owner','myModelA'

    Data Types: char | string

    When model configuration parameter Array layout is set to Row-major, a flag that indicates whether to preserve dimensions of a data element represented in generated code as a multidimensional array. Applies to storage classes Const, ConstVolatile, , ExportToFile, FileScope, ImportFromFile, Localizable, and Volatile.

    Example: 'PreserveDimensions','True'

    Data Types: logical

    Name of a set function that a data element calls in the generated code. Applies to storage class GetSet.

    Example: 'SetFunction','myDataSetFunction'

    Data Types: char | string

    Name that the code generator uses to identify the structure for a data element in the generated code. Applies to storage classes Bitfield and Struct.

    Example: 'StructName','myDataStruct'

    Storage class property defined in the Embedded Coder Dictionary. Values that you can specify vary depending on the storage class definition.

    Data Types: char | string
