ISCH_PrimitiveAttribute.isAsync() method
查询图元是否为异步图元
签名
typescript
function isAsync(): boolean;1
返回值
boolean
是否为异步图元
示例
javascript
// 1. 放置一个测试器件(属性图元随器件生成,无法单独创建)
const devices = await eda.lib_Device.search('C0402');
const comp = await eda.sch_PrimitiveComponent.create(devices[0], 600, 600);
const compId = comp.getState_PrimitiveId();
// 2. 取出器件的属性图元,定位 Designator(编号)属性
const attrIds = await eda.sch_PrimitiveAttribute.getAllPrimitiveId(compId);
const attrs = await eda.sch_PrimitiveAttribute.get(attrIds);
const designator = attrs.find(a => a.getState_Key() === 'Designator');
// 3. 查询异步状态
const isAsync = designator.isAsync();
// 4. 清理测试器件(属性图元随器件一起删除)
await eda.sch_PrimitiveComponent.delete([compId]);
console.log('isAsync:', isAsync);1
