KaFunctionCall

KaFunctionCall<S> represents a call to a function within Kotlin code — regular functions, constructors, superclass constructors, and annotations.

Hierarchy

Inherits KaSingleCall. (For historical reasons it also inherits the legacy KaCallableMemberCall; new code should treat KaFunctionCall as a KaSingleCall and use the inline accessors documented there.)

The following subtypes commit to a specific kind of function call:

KaImplicitInvokeCall — an implicit invoke call.
KaAnnotationCall — a call to an annotation constructor.
KaDelegatedConstructorCall — a this(...) or super(...) delegation.

Members

In addition to the KaSingleCall members (signature, dispatchReceiver, extensionReceiver, contextArguments, typeArgumentsMapping), KaFunctionCall adds argument mappings.

val valueArgumentMapping: Map<KtExpression, KaVariableSignature<KaValueParameterSymbol>>: A mapping from the call's argument expressions to their associated parameter symbols in a stable order. In case of vararg parameters, multiple arguments may be mapped to the same KaValueParameterSymbol.
val contextArgumentMapping: Map<KtExpression, KaVariableSignature<KaContextParameterSymbol>>: A mapping from the call's explicit context argument expressions to their associated context parameter symbols in a stable order.
val combinedArgumentMapping: Map<KtExpression, KaVariableSignature<KaParameterSymbol>>: A combined mapping from the call's argument expressions to their associated parameter symbols in a stable order. Includes both valueArgumentMapping and contextArgumentMapping. In case of vararg parameters, multiple arguments may be mapped to the same KaValueParameterSymbol.
val argumentMapping: Map<KtExpression, KaVariableSignature<KaValueParameterSymbol>> — deprecated: Use valueArgumentMapping (only value arguments) or combinedArgumentMapping (value + context arguments).
