Package kotlin

Base interface implicitly implemented by all annotation interfaces. See Kotlin language documentation for more information on annotations.

interface Annotation

The root of the Kotlin class hierarchy. Every Kotlin class has Any as a superclass.

open class Any

Represents an array (specifically, a Java array when targeting the JVM platform). Array instances can be created using the arrayOf, arrayOfNulls and emptyArray standard library functions. See Kotlin language documentation for more information on arrays.

class Array<T>

Represents a value which is either true or false. On the JVM, non-nullable values of this type are represented as values of the primitive type boolean.

class Boolean : Comparable<Boolean>

An array of booleans. When targeting the JVM, instances of this class are represented as boolean[].

class BooleanArray

Represents a 8-bit signed integer. On the JVM, non-nullable values of this type are represented as values of the primitive type byte.

class Byte : Number, Comparable<Byte>

An array of bytes. When targeting the JVM, instances of this class are represented as byte[].

class ByteArray

Represents a 16-bit Unicode character.

class Char : Comparable<Char>

An array of chars. When targeting the JVM, instances of this class are represented as char[].

class CharArray

Represents a readable sequence of Char values.

interface CharSequence

Classes which inherit from this interface have a defined total ordering between their instances.

interface Comparable<in T>

Provides a comparison function for imposing a total ordering between instances of the type T.

fun interface Comparator<T>

typealias Comparator<T> = Comparator<T>

Defines deep recursive function that keeps its stack on the heap, which allows very deep recursive computations that do not use the actual call stack. To initiate a call to this deep recursive function use its invoke function. As a rule of thumb, it should be used if recursion goes deeper than a thousand calls.

class DeepRecursiveFunction<T, R>

A scope class for DeepRecursiveFunction function declaration that defines callRecursive methods to recursively call this function or another DeepRecursiveFunction putting the call activation frame on the heap.

sealed class DeepRecursiveScope<T, R>

Possible levels of a deprecation. The level specifies how the deprecated element usages are reported in code.

enum class DeprecationLevel

Represents a double-precision 64-bit IEEE 754 floating point number. On the JVM, non-nullable values of this type are represented as values of the primitive type double.

class Double : Number, Comparable<Double>

An array of doubles. When targeting the JVM, instances of this class are represented as double[].

class DoubleArray

The common base class of all enum classes. See the Kotlin language documentation for more information on enum classes.

abstract class Enum<E : Enum<E>> : Comparable<E>

class Enum<T : Enum<T>> : Comparable<Enum<T>>

Represents a single-precision 32-bit IEEE 754 floating point number. On the JVM, non-nullable values of this type are represented as values of the primitive type float.

class Float : Number, Comparable<Float>

An array of floats. When targeting the JVM, instances of this class are represented as float[].

class FloatArray

Represents a value of a functional type, such as a lambda, an anonymous function or a function reference.

Represents a value with lazy initialization.

interface Lazy<out T>

Specifies how a Lazy instance synchronizes initialization among multiple threads.

enum class LazyThreadSafetyMode

Represents a 64-bit signed integer. On the JVM, non-nullable values of this type are represented as values of the primitive type long.

class Long : Number, Comparable<Long>

An array of longs. When targeting the JVM, instances of this class are represented as long[].

class LongArray

Nothing has no instances. You can use Nothing to represent "a value that never exists": for example, if a function has the return type of Nothing, it means that it never returns (always throws an exception).

class Nothing

Superclass for all platform classes representing numeric values.

abstract class Number

Represents a generic pair of two values.

data class Pair<out A, out B> : Serializable

A discriminated union that encapsulates a successful outcome with a value of type T or a failure with an arbitrary Throwable exception.

class Short : Number, Comparable<Short>

class ShortArray

The String class represents character strings. All string literals in Kotlin programs, such as "abc", are implemented as instances of this class.

class String : Comparable<String>, CharSequence

The base class for all errors and exceptions. Only instances of this class can be thrown or caught.

open class Throwable

Represents a triad of values

data class Triple<out A, out B, out C> : Serializable

The type with only one value: the Unit object. This type corresponds to the void type in Java.

object Unit

Allows to infer generic type arguments of a function from the calls in the annotated function parameter of that function.

annotation class BuilderInference

Marks the annotated declaration as deprecated.

annotation class Deprecated

Marks the annotated declaration as deprecated. In contrast to Deprecated, severity of the reported diagnostic is not a constant value, but differs depending on the API version of the usage (the value of the -api-version argument when compiling the module where the usage is located). If the API version is greater or equal than hiddenSince, the declaration will not be accessible from the code (as if it was deprecated with level DeprecationLevel.HIDDEN), otherwise if the API version is greater or equal than errorSince, the usage will be marked as an error (as with DeprecationLevel.ERROR), otherwise if the API version is greater or equal than warningSince, the usage will be marked as a warning (as with DeprecationLevel.WARNING), otherwise the annotation is ignored.

annotation class DeprecatedSinceKotlin

When applied to annotation class X specifies that X defines a DSL language

annotation class DslMarker

Signals that the annotated annotation class is a marker of an experimental API.

annotation class Experimental

The experimental multiplatform support API marker.

annotation class ExperimentalStdlibApi

Marks the API that is dependent on the experimental unsigned types, including those types themselves.

annotation class ExperimentalUnsignedTypes

Signifies that the annotated functional type represents an extension function.

annotation class ExtensionFunctionType

This annotation is present on any class file produced by the Kotlin compiler and is read by the compiler and reflection. Parameters have very short JVM names on purpose: these names appear in all generated class files, and we'd like to reduce their size.

annotation class Metadata

Allows to use the API denoted by the given markers in the annotated file, declaration, or expression. If a declaration is annotated with OptIn, its usages are not required to opt in to that API.

annotation class OptIn

Marks an expected annotation class that it isn't required to have actual counterparts in all platforms.

annotation class OptionalExpectation

Enables overload selection based on the type of the value returned from lambda argument.

annotation class OverloadResolutionByLambdaReturnType

Annotates type arguments of functional type and holds corresponding parameter name specified by the user in type declaration (if any).

annotation class ParameterName

When applied to a class or a member with internal visibility allows to use it from public inline functions and makes it effectively public.

annotation class PublishedApi

Specifies a code fragment that can be used to replace a deprecated function, property or class. Tools such as IDEs can automatically apply the replacements specified through this annotation.

annotation class ReplaceWith

Signals that the annotated annotation class is a marker of an API that requires an explicit opt-in.

annotation class RequiresOptIn

Specifies the first version of Kotlin where a declaration has appeared. Using the declaration and specifying an older API version (via the -api-version command line option) will result in an error.

annotation class SinceKotlin

Suppresses the given compilation warnings in the annotated element.

annotation class Suppress

This annotation indicates what exceptions should be declared by a function when compiled to a platform method in Kotlin/JVM and Kotlin/Native.

annotation class Throws

typealias Throws = Throws
