SparseFloatArray

open class SparseFloatArray : Cloneable

SparseFloatArray map integers to floats similar to android.util.SparseIntArray

Constructors

constructor()
Creates a new SparseFloatArray containing no mappings.
constructor(initialCapacity: Int)
Creates a new SparseFloatArray containing no mappings that will not require any additional memory allocation to store the specified number of mappings.

Functions

open fun append(key: Int, value: Float)
Puts a key/value pair into the array, optimizing for the case where the key is greater than all existing keys in the array.

@Nullable
open fun copyKeys(): Array<Int>
Provides a copy of keys.

open fun delete(key: Int)
Removes the mapping from the specified key, if there was any.
Link copied to clipboard
open fun get(key: Int): Float
Gets the float mapped from the specified key, or 0f if no such mapping has been made.
open fun get(key: Int, valueIfKeyNotFound: Float): Float
Gets the float mapped from the specified key, or the specified value if no such mapping has been made.

open fun indexOfKey(key: Int): Int
Returns the index for which keyAt would return the specified key, or a negative number if the specified key is not mapped.
Link copied to clipboard
open fun indexOfValue(value: Float): Int
Returns an index for which valueAt would return the specified key, or a negative number if no keys map to the specified value.
Link copied to clipboard
open fun keyAt(index: Int): Int
Given an index in the range 0...size()-1, returns the key from the index th key-value mapping that this SparseFloatArray stores.
Link copied to clipboard
open fun put(key: Int, value: Float)
Adds a mapping from the specified key to the specified value, replacing the previous mapping from the specified key if there was one.

open fun removeAt(index: Int)
Removes the mapping at the given index.

open fun setValueAt(index: Int, value: Float)
Directly set the value at a particular index.

open fun size(): Int
Returns the number of key-value mappings that this SparseFloatArray currently stores.
Link copied to clipboard
open fun toString(): String
This implementation composes a string by iterating over its mappings.

open fun valueAt(index: Int): Float
Given an index in the range 0...size()-1, returns the value from the index th key-value mapping that this SparseFloatArray stores.
