Kotlin Flow - 有没有类似于 LiveData 的 emitSource 的东西?
Kotlin Flow - is there anything similar to LiveData's emitSource?
我有一个函数接受一个返回 Flow 的参数函数,
fun <T> resultFlow(
query: () -> Flow<T>,
... other parameters
): Flow<T> {
return flow {
val source = query()
//!!!! emit(source) // I want something like emitSource like livedata has
...
}
请问有什么可以让流量可以这样发送的吗?
如果你想从流中发出所有项目,这正是 emitAll()
所做的:
fun <T> resultFlow(
query: () -> Flow<T>,
... other parameters
): Flow<T> {
return flow {
val source = query()
// Note that this will suspend until all values from the flow are collected.
emitAll(source)
}
