ImplementationDataType

XML tag	<IMPLEMENTATION-DATA-TYPE>
Module	autosar.datatype
Inherits	autosar.element.Element

Implementation Data Types is a very generic container and can define almost any data type.

Usage

import autosar

def setup():
    ws = autosar.workspace(version="4.2.2")
    package=ws.createPackage('DataTypes', role='DataType')
    package.createSubPackage('CompuMethods', role='CompuMethod')
    package.createSubPackage('DataConstrs', role='DataConstraint')
    baseTypes=package.createSubPackage('BaseTypes')
    baseTypes.createSwBaseType('dtRef_const_VOID', encoding = 'VOID', nativeDeclaration = 'void')
    baseTypes.createSwBaseType('uint8', 8, nativeDeclaration='uint8')
    package.createSubPackage('ImplementationTypes')
    return ws

ws = setup()
implTypes = ws.find('/DataTypes/ImplementationTypes')

#Basic Implementation Type
uint8_BaseRef = '/DataTypes/BaseTypes/uint8'
uint8_Impl = implTypes.createImplementationDataType('uint8', lowerLimit=0, upperLimit=255,
    baseTypeRef = uint8_BaseRef, typeEmitter='Platform_Type')
#Type Reference
implTypes.createImplementationDataTypeRef('OffOn_T', implementationTypeRef = uint8_Impl.ref,
    valueTable = ['OffOn_Off', 'OffOn_On', 'OffOn_Error', 'OffOn_NotAvailable'])

#Pointer Type
dtRef_const_VOID_BaseRef = '/DataTypes/BaseTypes/dtRef_const_VOID'
implTypes.createImplementationDataTypePtr('dtRef_const_VOID', dtRef_const_VOID_BaseRef, swImplPolicy = 'CONST')

ws.saveXML('DataTypes.arxml')

Factory Methods

Basic Implementation Types

In its simplest form, an implementation data type is just a reference to a SwBaseType with optional data constraint and compuMethod. Use the Package.createImplementationDataType method to create basic implementation types.

Type References

You can also create an implementation data type that references another implementation data type. This is known as typedef in the C programming language. Use the Package.createImplementationDataTypeRef method to create type references.

Pointer Types

You can create data types that are pointers to base types. A future release should be able to support pointers to other implementation types. Use the Package.createImplementationDataTypePtr method to create pointer types.

Array Types

You can create implementation data types that are arrays of other implementation data types. Use the createImplementationArrayDataType to create array data types.

Record Types

You can create implementation data types that are records of other implementation data types. Use the createImplementationRecordDataType to create record data types.

Note: Record types are sometimes called structs or structure types.

Constructor

datatype.ImplementationDataType(name[, variantProps = None][, dynamicArraySizeProfile = None][, typeEmitter = None][, category='VALUE'][, parent = None][, adminData = None])

参数

• name (str) – Short name.

• variantProps (None, SwDataDefPropsConditional, list) – variant properties.

• dynamicArraySizeProfile (None, str) – Dynamic array size profile.

• typeEmitter (None, str) – Type emitter

• category (None, str) – Category string.

• parent (None, Package) – Parent package.

• adminData (None, AdminData) – Admin data.

Attributes

For inherited attributes see autosar.element.Element.

Public Methods

• setSymbolProps

Method Description

setSymbolProps

ImplementationDataType.setSymbolProps([name = None][, symbol = None])

参数

• name (None, str) – Short name.

• symbol (None, str) – Symbol name.

Assigns the symbolProps attribute by creating a new instance of SymbolProps.
