KaCompoundAssignOperation¶

@SubclassOptInRequired(markerClass = [KaImplementationDetail::class])
interface KaCompoundAssignOperation : KaCompoundOperation

A compound assignment that reads, computes, and writes the computed value. Calls to <op>Assign are not represented by KaCompoundAssignOperation.

Types¶

`Kind`¶

enum class Kind : Enum<KaCompoundAssignOperation.Kind>

Properties¶

kind¶

abstract val kind: KaCompoundAssignOperation.Kind

The kind of assignment operation (+=, -=, and so on).

operand¶

abstract val operand: KtExpression

The right-hand operand of the compound assignment.

As for the left-hand operand (the variable or array element expression), it is represented in the call variants, KaVariableAccessCall and KaCompoundArrayAccessCall, which contain the KaCompoundOperation.

operationCall¶

abstract val operationCall: KaFunctionCall<KaNamedFunctionSymbol>

A call of the function that computes the value for this compound access. For example, if the access is +=, this is the plus function call. If the access is ++, this is the inc function call

`token`¶

abstract val token: KaLifetimeToken

The KaLifetimeToken which determines the lifetime of the lifetime owner.

Functions¶

`assertIsValidAndAccessible`¶

inline fun KaLifetimeOwner.assertIsValidAndAccessible()

`isValid`¶

fun KaLifetimeOwner.isValid(): Boolean

Whether the lifetime owner is still valid, i.e. we are still in the scope of the lifetime owner's regular lifetime.

`withValidityAssertion`¶

inline fun <R> KaLifetimeOwner.withValidityAssertion(action: () -> R): R

Executes action only if the KaLifetimeOwner is still valid and accessible. Otherwise, throws a validity exception based on the concrete violation.
