Boolean

Common
JVM
JS

1.0
class Boolean : Comparable<Boolean>
(Common source) (Native source)

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.

Functions

1.0

and

Performs a logical and operation between this Boolean and the other one. Unlike the && operator, this function does not perform short-circuit evaluation. Both this and other will always be evaluated.

infix fun and(other: Boolean): Boolean
Common
JVM
JS
Native
1.0

compareTo

Compares this object with the specified object for order. Returns zero if this object is equal to the specified other object, a negative number if it's less than other, or a positive number if it's greater than other.

fun compareTo(other: Boolean): Int

equals

Native
1.3
fun equals(other: Boolean): Boolean
Common
JVM
JS
Native
1.0

Indicates whether some other object is "equal to" this one. Implementations must fulfil the following requirements:

fun equals(other: Any?): Boolean

hashCode

Returns a hash code value for the object. The general contract of hashCode is:

fun hashCode(): Int

not

Returns the inverse of this boolean.

operator fun not(): Boolean
Common
JVM

Native
1.0

or

Performs a logical or operation between this Boolean and the other one. Unlike the || operator, this function does not perform short-circuit evaluation. Both this and other will always be evaluated.

infix fun or(other: Boolean): Boolean

toString

Returns a string representation of the object.

fun toString(): String

xor

Performs a logical xor operation between this Boolean and the other one.

infix fun xor(other: Boolean): Boolean

coerceAtLeast

Ensures that this value is not less than the specified minimumValue.

fun <T : Comparable<T>> T.coerceAtLeast(minimumValue: T): T

coerceAtMost

Ensures that this value is not greater than the specified maximumValue.

1.0

coerceIn

Ensures that this value lies in the specified range minimumValue..maximumValue.

fun <T : Comparable<T>> T.coerceIn(
    minimumValue: T?,
    maximumValue: T?
): T

Ensures that this value lies in the specified range.

fun <T : Comparable<T>> T.coerceIn(
    range: ClosedFloatingPointRange<T>
): T
fun <T : Comparable<T>> T.coerceIn(range: ClosedRange<T>): T

compareTo

Compares this object with the specified object for order. Returns zero if this object is equal to the specified other object, a negative number if it's less than other, or a positive number if it's greater than other.

infix fun <T> Comparable<T>.compareTo(other: T): Int

rangeTo

Creates a range from this Comparable value to the specified that value.

operator fun <T : Comparable<T>> T.rangeTo(
    that: T
): ClosedRange<T>
Common

1.9

rangeUntil

Creates an open-ended range from this Comparable value to the specified that value.

    that: T
): OpenEndRange<T>
