类 LinkedMultiValueMap<K,V>

java.lang.Object

com.jn.langx.util.collection.multivalue.CommonMultiValueMap<K,V>

com.jn.langx.util.collection.multivalue.LinkedMultiValueMap<K,V>

类型参数:

K - the key type

V - the value element type

所有已实现的接口:

MultiValueMap<K,V>, Serializable, Cloneable, Map<K,Collection<V>>

public class LinkedMultiValueMap<K,V>
extends CommonMultiValueMap<K,V>
implements Serializable, Cloneable

Simple implementation of MultiValueMap that wraps a LinkedHashMap, storing multiple values in a LinkedList.

This Map implementation is generally not thread-safe. It is primarily designed for data structures exposed from request objects, for use in a single thread only.

LinkedMultiValueMap

public LinkedMultiValueMap()

Create a new LinkedMultiValueMap that wraps a LinkedHashMap.

LinkedMultiValueMap

public LinkedMultiValueMap(int initialCapacity)

Create a new LinkedMultiValueMap that wraps a LinkedHashMap with the given initial capacity.

参数:

initialCapacity - the initial capacity

LinkedMultiValueMap

public LinkedMultiValueMap(Map<K,List<V>> otherMap)

Copy constructor: Create a new LinkedMultiValueMap with the same mappings as the specified Map. Note that this will be a shallow copy; its value-holding List entries will get reused and therefore cannot get modified independently.

参数:

otherMap - the Map whose mappings are to be placed in this Map

方法详细资料

containsValue

public boolean containsValue(Object value)

指定者:

containsValue 在接口中 Map<K,Collection<V>>

覆盖:

containsValue 在类中 CommonMultiValueMap<K,V>

deepCopy

public LinkedMultiValueMap<K,V> deepCopy()

Create a deep copy of this Map.

返回:

a copy of this Map, including a copy of each value-holding List entry (consistently using an independent modifiable LinkedList for each entry) along the lines of MultiValueMap.addAll semantics

另请参阅:

CommonMultiValueMap.addAll(MultiValueMap), clone()

clone

public LinkedMultiValueMap<K,V> clone()

Create a regular copy of this Map.

覆盖:

clone 在类中 Object

返回:

a shallow copy of this Map, reusing this Map's value-holding List entries (even if some entries are shared or unmodifiable) along the lines of standard Map.put semantics

CommonMultiValueMap.putAll(Map), LinkedMultiValueMap(Map), deepCopy()

equals

public boolean equals(@Nullable
                      Object obj)

指定者:

equals 在接口中 Map<K,Collection<V>>

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

指定者:

hashCode 在接口中 Map<K,Collection<V>>

覆盖:

hashCode 在类中 Object

toString

public String toString()

覆盖:

toString 在类中 Object
