KaFunctionTypeFamily¶
@SubclassOptInRequired(markerClass = [KaImplementationDetail::class])
interface KaFunctionTypeFamily : KaFunctionTypeFamily
The type has been moved to a new package. Use <strong>org.jetbrains.kotlin.analysis.api.types.KaFunctionTypeFamily</strong> instead.
Describes a family of numbered function types such as Function0, Function1, ..., FunctionN.
Kotlin has the following built-in function type families:
-
Function— regular function types, e.g.,(Int) -> String -
SuspendFunction— suspend function types, e.g.,suspend () -> Unit -
KFunction— reflection types for regular functions -
KSuspendFunction— reflection types for suspend functions
Compiler plugins may introduce additional custom function type families.

Properties¶
isInlinable¶
abstract override val isInlinable: Boolean
Whether function types in this family can be inlined by the compiler.
For built-in families, Function and SuspendFunction are inlinable, while KFunction and KSuspendFunction are not.
isReflect¶
Whether this family represents reflection function types (KFunction, KSuspendFunction).
isSuspend¶
Whether this family represents suspend function types (SuspendFunction, KSuspendFunction).
markerAnnotationClassId¶
abstract val markerAnnotationClassId: ClassId?
The ClassId of the annotation which marks a function type as belonging to this family, such as androidx.compose.runtime.Composable.
maxArity¶
The maximum number of parameters supported by function types in this family.
nameBase¶
The class name prefix shared by all types in this family.
For example, "Function" for the Function family, "SuspendFunction" for the SuspendFunction family.
supportsConversionFromSimpleFunctionType¶
abstract override val supportsConversionFromSimpleFunctionType: Boolean
Whether function references with a simple function type (e.g., Function0, KFunction0) can be converted to this family.
typeRenderingPrefix¶
abstract val typeRenderingPrefix: String?
The prefix which precedes a function type of this family when the type is rendered, such as "suspend" for the SuspendFunction family, or "@Composable" for the ComposableFunction family provided by the Compose compiler plugin.
