KCallable
Properties
isAbstract
true
if this callable is
abstract
.
abstract
val
isAbstract
:
Boolean
isFinal
true
if this callable is
final
.
abstract
val
isFinal
:
Boolean
isOpen
true
if this callable is
open
.
abstract
val

:
Boolean
isSuspend
true
if this is a suspending function.
abstract
val
isSuspend
:
Boolean
name
The name of this callable as it was declared in the source code. If the callable has no name, a special invented name is created. Nameless callables include:
abstract
val
name
:
String
parameters
Parameters required to make a call to this callable.
If this callable requires a
this
instance or an extension receiver parameter,
they come first in the list in that order.
abstract
val
parameters
:
List
<
KParameter
>
returnType
The type of values returned by this callable.
abstract
val
returnType
:
KType
typeParameters
The list of type parameters of this callable.
abstract
val
typeParameters
:
List
<
KTypeParameter
>
visibility
Visibility of this callable, or
null
if its visibility cannot be represented in Kotlin.

Functions
call
Calls this callable with the specified list of arguments and returns the result. Throws an exception if the number of specified arguments is not equal to the size of parameters , or if their types do not match the types of the parameters.
abstract
fun
call
(
vararg
args
:
Any
?
)
:

callBy
Calls this callable with the specified mapping of parameters to arguments and returns the result. If a parameter is not found in the mapping and is not optional (as per KParameter.isOptional ), or its type does not match the type of the provided value, an exception is thrown.

Extension Properties
extensionReceiverParameter
Returns a parameter representing the extension receiver instance needed to call this callable,
or
null
if this callable is not an extension.
val

.
extensionReceiverParameter
:
KParameter
?
instanceParameter
Returns a parameter representing the
this
instance needed to call this callable,
or
null
if this callable is not a member of a class and thus doesn't take such parameter.
val
KCallable
<

instanceParameter
:
KParameter
?
isAccessible
Provides a way to suppress JVM access checks for a callable.

valueParameters
Returns parameters of this callable, excluding the
this
instance and the extension receiver parameter.
