Array
class Array<T>
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.
Constructors
Array(size: Int, init: (Int) -> T) Creates a new array with the specified size, where each element is calculated by calling the specified init function. The init function returns an array element given its index. |
Properties
val size: Int Returns the number of elements in the array. |
Functions
operator fun get(index: Int): T Returns the array element at the specified index. This method can be called using the index operator: | |
operator fun iterator(): Iterator<T> Creates an iterator for iterating over the elements of the array. | |
operator fun set(index: Int, value: T) Sets the array element at the specified index to the specified value. This method can be called using the index operator: |
Inherited Functions
open operator fun equals(other: Any?): Boolean Indicates whether some other object is "equal to" this one. Implementations must fulfil the following requirements: | |
open fun hashCode(): Int Returns a hash code value for the object. The general contract of hashCode is: | |
open fun toString(): String Returns a string representation of the object. |
Extension Properties
