KaImplicitInvokeCall

KaImplicitInvokeCall represents an implicit invoke operator call — a call on a value whose type has an invoke member function.

interface Foo {
    operator fun <T> invoke(t: T)
}

fun test(f: Foo) {
    f("str")
//  ^^^^^^^^
}

f("str") is the implicit form of f.invoke("str") and resolves to a KaImplicitInvokeCall.

Hierarchy

Inherits KaFunctionCall (KaImplicitInvokeCall : KaFunctionCall<KaNamedFunctionSymbol>).

KaImplicitInvokeCall does not add new members beyond KaFunctionCall. The intended use is a type check:

val call: KaFunctionCall<*>? = callElement.resolveCall()
if (call is KaImplicitInvokeCall) {
    handleImplicitInvoke(call)
}

This replaces the deprecated KaSimpleFunctionCall.isImplicitInvoke boolean from the legacy API.
