setDataDefault
Description
setDataDefault(
sets the default storage class and storage class property values in the code mappings for
the specified category of model data.myCoderDictionaryObj
,category
,Name,Value
)
Examples
Configure default code settings for a data category in a data dictionary
Use the coder.mapping.api.get
function to access the
CoderDictionary
object associated with the data dictionary.
cm = coder.mapping.api.get('codeDefinitions.sldd');
To see the storage class of root-level inports for the dictionary, use the
getDataDefault
function.
value = getDataDefault(cm, 'Inports', 'StorageClass')
value = 'Default'
The dictionary uses the default storage class for inports.
To configure the storage class, use the setDataDefault
function.
setDataDefault(cm, 'Inports', 'StorageClass', 'ExportedGlobal')
To verify that the storage class of inports is now set to
ExportedGlobal
, use the getDataDefault
function.
value = getDataDefault(cm, 'Inports', 'StorageClass')
value = 'ExportedGlobal'
Input Arguments
myCoderDictionaryObj
— Coder dictionary object
CoderDictionary
object
Coder dictionary object returned by a call to function
coder.mapping.api.get
.
category
— Model data element category
Constants
| ExternalParameterObjects
| GlobalDataStores
| Inports
| InternalData
| ModelParameters
| ModelParameterArguments
| Outports
| SharedLocalDataStores
Category of data elements to return a property value for.
Example: 'Inports'
Name-Value 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 name
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'
DefinitionFile

character vector | string scalar
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

, and
Volatile
.
Example: 'DefinitionFile','myDataDefs.c'
Data Types: char
| string
GetFunction
— Name of get function
character vector | string scalar
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

,
ExportToFile
, GetSet
,
ImportedDefine
, ImportFromFile
, and
Volatile
.
Example: 'HeaderFile','myDataDecl.h'
Data Types: char

MemorySection
— Name of memory section
character vector | string scalar
Name of a memory section that is defined in the Embedded Coder Dictionary associated with the model.
Example: 'MemorySection','myFastMem'
Data Types: char
| string
Owner
— Owner of global data
character vector | string scalar
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
PreserveDimensions
— Boolean flag indicating whether to preserve dimensions of multidimensional arrays
True
| False
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
SetFunction
— Name of set function
character string | string scalar
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
StructName
— Name of structure
character vector | string scalar
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'
storageClassPropertyName
— Value of storage class property
depends on property definition
Storage class property defined in the Embedded Coder Dictionary. Values that you can specify vary depending on the storage class definition.
