Kotlin对象比较注意点示例详解

private val stateFlow = MutableStateFlow(kotlin.Pair>("abc", ArrayList()))

GlobalScope.launch { stateFlow.collect { // do something } }

GlobalScope.launch { stateFlow.value.second.add("test") stateFlow.emit(stateFlow.value) }

override suspend fun emit(value: T) { this.value = value }

public override var value: T get() = NULL.unbox(_state.value) set(value) { updateState(null, value ?: NULL) }

private fun updateState(expectedState: Any?, newState: Any): Boolean { var curSequence = 0 var curSlots: Array? = this.slots // benign race, we will not use it synchronized(this) { val oldState = _state.value if (expectedState != null && oldState != expectedState) return false // CAS support if (oldState == newState) return true // Don't do anything if value is not changing, but CAS -> true _state.value = newState curSequence = sequence ... 省略部分代码 } }

GlobalScope.launch { stateFlow.value.apply { stateFlow.emit(kotlin.Pair(first, second)) } }

public final class Pair { public int hashCode() { Object var10000 = this.first; int var1 = (var10000 != null ? var10000.hashCode() : 0) * 31; Object var10001 = this.second; return var1 + (var10001 != null ? var10001.hashCode() : 0); } public boolean equals(@Nullable Object var1) { if (this != var1) { if (var1 instanceof Te.Pair) { Te.Pair var2 = (Te.Pair) var1; if (Intrinsics.areEqual(this.first, var2.first) && Intrinsics.areEqual(this.second, var2.second)) { return true; } } return false; } else { return true; } } }
