Represents an annotated element and allows to obtain its annotations. See the Kotlin language documentation for more information.

Represents a callable entity, such as a function or a property.

Represents a class and provides introspection capabilities. Instances of this class are obtainable by the ::class syntax. See the Kotlin language documentation for more information.

A classifier is either a class or a type parameter.

Represents an entity which may contain declarations of any other entities, such as a class or a package.

Represents a function with introspection capabilities.

Represents a property declared as a var.

Represents a var-property without any kind of receiver.

Represents a var-property, operations on which take one receiver as a parameter.

Represents a var-property, operations on which take two receivers as parameters.

Represents a parameter passed to a function or a property getter/setter, including this and extension receiver parameters.

Represents a property, such as a named val or var declaration. Instances of this class are obtainable by the :: operator.

Represents a property without any kind of receiver. Such property is either originally declared in a receiverless context such as a package, or has the receiver bound to it.

Represents a property, operations on which take one receiver as a parameter.

Represents a property, operations on which take two receivers as parameters, such as an extension property declared in a class.

Represents a type. Type is usually either a class with optional type arguments, or a type parameter of some declaration, plus nullability.

Represents a declaration of a type parameter of a class or a callable. See the Kotlin language documentation for more information.

Represents a type projection. Type projection is usually the argument to another type in a type usage. For example, in the type Array<out Number>, out Number is the covariant projection of the type represented by the class Number.

Represents variance applied to a type parameter on the declaration site (declaration-site variance), or to a type in a projection (use-site variance).

Visibility is an aspect of a Kotlin declaration regulating where that declaration is accessible in the source code. Visibility can be changed with one of the following modifiers: public, protected, internal, private.

Makes the annotated annotation class an associated object key.

The experimental marker for associated objects API.

Returns a Java Type instance corresponding to the given Kotlin type.

Casts the given value to the class represented by this KClass object. Throws an exception if the value is null or if it is not an instance of this class.

Creates a new instance of the class, calling a constructor which either has no parameters or all parameters of which have a default value. If there are no or many such constructors, an exception is thrown.

If T is an @AssociatedObjectKey-annotated annotation class and this class is annotated with @T (S::class), returns object S.

Casts the given value to the class represented by this KClass object. Returns null if the value is null or if it is not an instance of this class.

Returns a runtime representation of the given reified type T as an instance of KType.
