**依赖约束：**
|
||||
- `core` → 无依赖（最底层）
|
||||
- `types` → 依赖 `core`
|
||||
- `utils` → 依赖 `core`
|
||||
- `tests` → 依赖 `src` 所有模块
|
||||
|
||||
## 设计模式
|
||||
|
||||
### 1. 工厂函数模式
|
||||
|
||||
所有类型都配有 `create_xxx()` 工厂函数，简化对象创建：
|
||||
|
||||
```python
|
||||
# 使用工厂函数
|
||||
uint8 = create_base_type("UInt8", size=8)
|
||||
|
||||
# 替代直接实例化（如果存在构造函数）
|
||||
uint8 = BaseType(name="UInt8", size=8)
|
||||
```
|
||||
|
||||
### 2. 组合模式
|
||||
|
||||
通过 `add_xxx()` 方法支持动态添加子元素：
|
||||
|
||||
```python
|
||||
component = ApplicationSwComponentType(name="Sensor")
|
||||
component.add_port(PPortPrototype(name="DataPort"))
|
||||
```
|
||||
|
||||
### 3. 序列化模式
|
||||
|
||||
所有类型都实现 `to_arxml(doc)` 方法，将自身序列化为 ARXML DOM 元素：
|
||||
|
||||
```python
|
||||
element = component.to_arxml(doc)
|
||||
```
|
||||
|
||||
### 4. 数据类模式
|
||||
|
||||
使用 `@dataclass` 简化数据类定义：
|
||||
|
||||
```python
|
||||
@dataclass
|
||||
class BaseType:
|
||||
name: str
|
||||
size: int
|
||||
category: Optional[Category] = None
|
||||
encoding: Optional[Encoding] = None
|
||||
```
|
||||

||||

|

## 快速开始
|
||||
|
||||
### 环境要求
|
||||
|
||||
- Python 3.8+
|
||||
|
||||
### 安装
|
||||
|
||||
将 `src` 目录添加到 Python 路径即可使用：
|
||||
|
||||
```python
|
||||
import sys
|
||||
sys.path.insert(0, '/path/to/arxml_sdk/src')
|
||||
```
|
||||
|
||||
或直接使用相对导入：
|
||||
|
||||
```python
|
||||
from src import create_arxml_document, write_arxml
|
||||
```
|
||||
|
||||
### 最小示例
|
||||
|
||||
```python
|
||||
from src import (
|
||||
create_arxml_document, write_arxml, create_package,
|
||||
create_base_type, Category, Encoding
|
||||
)
|
||||
|
||||
doc = create_arxml_document()
|
||||
base_type = create_base_type("UInt8", size=8, encoding=Encoding.TWO_COMPONENT)
|
||||
package = create_package("MyPackage", elements=[base_type])
|
||||
package_element = package.to_arxml(doc)
|
||||
doc.documentElement.appendChild(package_element)
|
||||
write_arxml(doc, "minimal.arxml")
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 基础类型创建
|
||||
|
||||
### 创建基本整数类型
|
||||
|
||||
```python
|
||||
from src import create_base_type, Category, Encoding
|
||||
|
||||
uint8 = create_base_type("UInt8", size=8, encoding=Encoding.TWO_COMPONENT)
|
||||
uint16 = create_base_type("UInt16", size=16, encoding=Encoding.TWO_COMPONENT)
|
||||
sint8 = create_base_type("Sint8", size=8, encoding=Encoding.TWO_COMPONENT)
|
||||
float32 = create_base_type("Float32", size=32, encoding=Encoding.IEEE754)
|
||||
```
|
||||
|
||||
### 创建带文本表的类型

||||
```python
|
||||
from src import (

||||
create_linear, create_text_table, create_compu_method,
|
||||
Category, LowerSts, UpperSts
|
||||
)
|
||||
|
||||
unit = create_unit("km/h", display="km/h", factor=1.0, offset=0.0)
|
||||
|
||||
constraint = create_data_constraint(
|
||||
"SpeedConstraint",
|
||||
lower=0, upper=250,
|
||||
lower_sts=LowerSts.CLOSED,
|
||||
upper_sts=UpperSts.OPEN
|
||||
)
|
||||
|
||||
linear = create_linear(factor=0.01, offset=0)
|
||||
|
||||
compu = create_compu_method(
|
||||
"SpeedConversion",
|
||||
unit=unit,
|
||||
linear=linear,
|
||||
category=Category.LINEAR
|

### 发送-接收接口
|
||||
|
||||
```python
|
||||
from src import (
|
||||
SenderReceiverInterface, create_sender_receiver_interface,
|
||||
create_value_type, create_unit, Policy, CalibrationAccess
|
||||
)
|
||||
|
||||
unit = create_unit("km/h")
|
||||
data_element = SenderReceiverInterface.DataElement(
|
||||
name="Speed",
|
||||
data_type=create_value_type("Speed", unit=unit),
|
||||
policy=Policy.STANDARD,
|
||||
calibration_access=CalibrationAccess.READ_ONLY
|
||||
)
|
||||
|
||||
interface = create_sender_receiver_interface("SpeedInterface", data_element=data_element)
|
||||
```
|
||||
|
||||
### 客户端-服务端接口
|
||||
|
||||
```python
|
||||
from src import (
|
||||
ClientServerInterface, create_value_type, create_unit,
|
||||
PortDirection
|
||||

]
|
||||
)
|
||||
|
||||
cs_interface = ClientServerInterface(name="ControlInterface")
|

cs_interface.add_operation(operation)
|
||||
```
|
||||

|
||||
|
||||
## 软件组件
|
||||
|
||||
### 创建组件
|
||||
|
||||
```python
|
||||
from src import (
|
||||
ApplicationSwComponentType, PPortPrototype, RPortPrototype,
|
||||
SenderReceiverInterface, create_sender_receiver_interface,
|
||||
AtomicType, ComponentType
|
||||
)
|
||||
|
||||
interface = create_sender_receiver_interface("DataInterface")
|
||||
port = PPortPrototype(name="DataPort", interface=interface)
|
||||
|
||||
component = ApplicationSwComponentType(
|
||||
name="SensorComponent",
|
||||
supports_multiple_instantiation=False,
|
||||
atomic_type=AtomicType.APPLICATION
|
||||
)
|
||||
component.add_port(port)
|
||||
```
|
||||
|
||||
### 创建组合组件
|
||||
|
||||
```python
|
||||
from src import SwComponentType, ComponentType, AtomicComponentType, CompositionSwComponentType
|
||||
|
||||
child1 = ApplicationSwComponentType(name="Child1")
|
||||
child2 = ApplicationSwComponentType(name="Child2")
|
||||
|
||||
composition = CompositionSwComponentType(name="Composition")
|
||||
composition._component_type = ComponentType.COMPOSITION
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 内部行为
|
||||
|
||||
### 创建 Runnable 和事件
|
||||
|
||||
```python
|
||||
from src import (
|
||||
SwcInternalBehavior, RunnableEntity, TimingEvent, InitEvent,
|
||||
VariableAccess, create_swc_internal_behavior, create_runnable_entity,
|
||||
create_timing_event, create_init_event, create_data_received_event
|
||||
)
|
||||
|
||||
runnable = create_runnable_entity(
|
||||
name="UpdateMeasurement",
|
||||
symbol="UpdateMeasurement",
|
||||
minimum_start_interval=0.01
|
||||
)
|
||||
runnable.add_variable_access(
|
||||
VariableAccess(name="SpeedAccess", port_prototype_ref="SpeedPort")
|
||||
)
|
||||
|
||||
timing_event = create_timing_event(name="Timing_10ms", period=0.01)
|
||||
init_event = InitEvent(name="Init", runnable_ref="UpdateMeasurement")
|
||||
|
||||
data_rx_event = create_data_received_event(
|
||||
name="DataReady",
|
||||
data_element_ref="ReadyFlag",
|
||||
period=0.05
|
||||
)
|
||||
|
||||
behavior = create_swc_internal_behavior(
|
||||
name="SensorBehavior",
|
||||
runnable_entities=[runnable],
|
||||
events=[timing_event, init_event, data_rx_event]
|
||||
)
|
||||
|
||||
component = ApplicationSwComponentType(name="Sensor")
|
||||
component.internal_behavior = behavior
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 打包与导出
|
||||
|
||||
### 基本导出流程
|
||||
|
||||
```python
|
||||
from src import (
|
||||
create_arxml_document, write_arxml, create_package,
|
||||
get_ar_packages_element, add_package_to_document,
|
||||
create_base_type, create_value_type, create_unit
|
||||
)
|
||||
|
||||
doc = create_arxml_document()
|
||||
packages_element = get_ar_packages_element(doc)
|
||||
|
||||
base_type = create_base_type("UInt8", size=8)
|
||||
app_type = create_value_type("AppData")
|
||||
package = create_package("MyPkg", elements=[base_type, app_type])
|
||||
|
||||
package_element = package.to_arxml(doc)
|
||||
add_package_to_document(doc, package_element)
|
||||
|
||||
write_arxml(doc, "output.arxml")
|
||||
```
|
||||
|
||||
### 格式化输出
|
||||
|
||||
```python
|
||||
from src import write_arxml_pretty
|
||||
|
||||
write_arxml_pretty(doc, "output_formatted.arxml")
|
||||
```

## 常见问题
|
||||
|
||||
### Q: 如何创建多个端口？
|
||||
|
||||
```python
|
||||
interface1 = create_sender_receiver_interface("DataInterface")
|
||||
interface2 = create_sender_receiver_interface("StatusInterface")
|
||||
|
||||
component = ApplicationSwComponentType(name="MyComponent")
|
||||
component.add_port(PPortPrototype(name="DataPort", interface=interface1))
|
||||
component.add_port(RPortPrototype(name="StatusPort", interface=interface2))
|
||||
```
|
||||
|
||||
### Q: 如何添加多个 Runnable？
|
||||
|
||||
```python
|
||||
behavior = SwcInternalBehavior(name="Behavior")
|
||||
|
||||
runnable1 = create_runnable_entity(name="InitRunnable", symbol="Init")
|
||||
runnable2 = create_runnable_entity(name="MainRunnable", symbol="Main", minimum_start_interval=0.01)
|
||||
|
||||
behavior.add_runnable(runnable1)
|
||||
behavior.add_runnable(runnable2)
|
||||
|
||||
component = ApplicationSwComponentType(name="MyComponent")
|
||||
component.internal_behavior = behavior
|
||||
```
|
||||
|
||||
### Q: 如何创建嵌套结构体？
|
||||
|
||||
```python
|
||||
inner_type = create_value_type("InnerValue")
|
||||
inner_struct = ApplicationStructureDataType(name="InnerStruct")
|
||||
inner_struct.add_element(
|
||||
ApplicationStructureDataType.StructureElement(name="value", data_type=inner_type)
|
||||
)
|
||||
|
||||
outer_struct = ApplicationStructureDataType(name="OuterStruct")
|
||||
outer_struct.add_element(
|
||||
ApplicationStructureDataType.StructureElement(name="inner", data_type=inner_struct)
|
||||
)
|
||||
```
