KFunctionAdapter

class KFunctionAdapter<T : OutputValue<*>>(function: KFunction<T>) : Function<T>

A Quarkdown Function adapted from a regular Kotlin KFunction.

Reflection metadata is read eagerly once at construction and cached as immutable state, so each call site (name lookup, parameter introspection, validator selection, invocation) is a direct field read rather than a fresh reflection scan.

Parameters

function

Kotlin function to adapt

Constructors

KFunctionAdapter

constructor(function: KFunction<T>)

Properties

invoke

open override val invoke: (ArgumentBindings, FunctionCall<T>) -> T

Function that maps the input arguments into an output value. Arguments and parameters compliance in terms of matching types and count is not checked here. The ArgumentBindings allow looking up argument values by their parameter.

name

open override val name: String

If the Name annotation is present on function, the Quarkdown function name is set from there. Otherwise, it is function's original name.

parameters

open override val parameters: List<FunctionParameter<*>>

Declared parameters.

validators

open override val validators: List<FunctionCallValidator<T>>

Validators that check the validity of a function call towards this function. If a condition is not met during the validation, an exception should be thrown.

Functions

signatureAsString

fun Function<*>.signatureAsString(includeName: Boolean = true): <Error class: unknown class>
