类 LinkedHashTreeMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

com.google.gson.internal.LinkedHashTreeMap<K,V>

所有已实现的接口:

Serializable, Map<K,V>

public final class LinkedHashTreeMap<K,V>
extends AbstractMap<K,V>
implements Serializable

A map of comparable keys to values. Unlike TreeMap, this class uses insertion order for iteration order. Comparison order is only used as an optimization for efficient insertion and removal.

This implementation was derived from Android 4.1's TreeMap and LinkedHashMap classes.

构造器详细资料

LinkedHashTreeMap

public LinkedHashTreeMap()

Create a natural order, empty tree map whose keys must be mutually comparable and non-null.

LinkedHashTreeMap

public LinkedHashTreeMap(Comparator<? super K> comparator)

Create a tree map ordered by comparator. This map's keys may only be null if comparator permits.

参数:

comparator - the comparator to order elements with, or null to use the natural ordering.
