ArraySet

ArraySet

ArraySet()

Create a new empty ArraySet. The default capacity of an array map is 0, and will grow once items are added to it.

ArraySet

ArraySet(capacity: Int)

Create a new ArraySet with a given initial capacity.

ArraySet

ArraySet(set: ArraySet<E>!)

Create a new ArraySet with the mappings from the given ArraySet.

ArraySet

ArraySet(set: MutableCollection<out E>!)

Create a new ArraySet with items from the given collection.

ArraySet

ArraySet(array: Array<E>?)

Create a new ArraySet with items from the given array

add

fun add(element: E): Boolean

Adds the specified object to this set. The set is not modified if it already contains the object.

addAll

fun addAll(array: ArraySet<out E>!): Unit

Perform a add(java.lang.Object) of all values in array

addAll

fun addAll(elements: Collection<E>): Boolean

Perform an add(java.lang.Object) of all values in collection

clear

fun clear(): Unit

Make the array map empty. All storage is released.

contains

fun contains(element: E): Boolean

Check whether a value exists in the set.

containsAll

fun containsAll(elements: Collection<E>): Boolean

Determine if the array set contains all of the values in the given collection.

ensureCapacity

fun ensureCapacity(minimumCapacity: Int): Unit

Ensure the array map can hold at least minimumCapacity items.

equals

fun equals(other: Any?): Boolean

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

This implementation returns false if the object is not a set, or if the sets have different sizes. Otherwise, for each value in this set, it checks to make sure the value also exists in the other set. If any value doesn't exist, the method returns false; otherwise, it returns true.

forEach

fun forEach(action: Consumer<in E>): Unit

Performs the given action for all elements in the stored order. This implementation overrides the default implementation to avoid using the #iterator().

hashCode

fun hashCode(): Int

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

indexOf

fun indexOf(key: Any!): Int

Returns the index of a value in the set.

isEmpty

fun isEmpty(): Boolean

Return true if the array map contains no items.

iterator

fun iterator(): MutableIterator<E>

Return an java.util.Iterator over all values in the set.

Note: this is a fairly inefficient way to access the array contents, it requires generating a number of temporary objects and allocates additional state information associated with the container that will remain for the life of the container.

remove

fun remove(element: E): Boolean

Removes the specified object from this set.

removeAll

fun removeAll(array: ArraySet<out E>!): Boolean

Perform a remove(java.lang.Object) of all values in array

removeAll

fun removeAll(elements: Collection<E>): Boolean

Remove all values in the array set that exist in the given collection.

removeAt

fun removeAt(index: Int): E

Remove the key/value mapping at the given index.

For indices outside of the range 0...size()-1, the behavior is undefined for apps targeting android.os.Build.VERSION_CODES#P and earlier, and an ArrayIndexOutOfBoundsException is thrown for apps targeting android.os.Build.VERSION_CODES#Q and later.

removeIf

fun removeIf(filter: Predicate<in E>): Boolean

Removes all values that satisfy the predicate. This implementation avoids using the #iterator().

retainAll

fun retainAll(elements: Collection<E>): Boolean

Remove all values in the array set that do not exist in the given collection.

toArray

fun toArray(): Array<Any!>!

toArray

fun <T : Any!> toArray(array: Array<T>!): Array<T>!

toString

fun toString(): String

Returns a string representation of the object.

This implementation composes a string by iterating over its values. If this set contains itself as a value, the string "(this Set)" will appear in its place.

valueAt

fun valueAt(index: Int): E

Return the value at the given index in the array.

For indices outside of the range 0...size()-1, the behavior is undefined for apps targeting android.os.Build.VERSION_CODES#P and earlier, and an ArrayIndexOutOfBoundsException is thrown for apps targeting android.os.Build.VERSION_CODES#Q and later.

size

val size: Int

Return the number of items in this array map.
