Remarks

A scalable concurrent ConcurrentNavigableMap implementation. The map is sorted according to the Comparable natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used.

This class implements a concurrent variant of SkipLists providing expected average log(n) time cost for the containsKey, get, put and remove operations and their variants. Insertion, removal, update, and access operations safely execute concurrently by multiple threads.

Iterators and spliterators are weakly consistent.

Ascending key ordered views and their iterators are faster than descending ones.

All Map.Entry pairs returned by methods in this class and its views represent snapshots of mappings at the time they were produced. They do not support the Entry.setValue method. (Note however that it is possible to change mappings in the associated map using put, putIfAbsent, or replace, depending on exactly which effect you need.)

Beware that bulk operations putAll, equals, toArray, containsValue, and clear are not guaranteed to be performed atomically. For example, an iterator operating concurrently with a putAll operation might view only some of the added elements.

This class and its views and iterators implement all of the optional methods of the Map and Iterator interfaces. Like most other concurrent collections, this class does not permit the use of null keys or values because some null return values cannot be reliably distinguished from the absence of elements.

This class is a member of the Java Collections Framework.

Constructors

ConcurrentSkipListMap()	Constructs a new, empty map, sorted according to the Comparable natural ordering of the keys.
ConcurrentSkipListMap(IComparator)	Constructs a new, empty map, sorted according to the specified comparator.
ConcurrentSkipListMap(IDictionary)	Constructs a new map containing the same mappings as the given map, sorted according to the Comparable natural ordering of the keys.
ConcurrentSkipListMap(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

Class	Returns the runtime class of this `Object`. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
IsEmpty	To be added (Inherited from AbstractMap)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Methods

CeilingEntry(Object)	Returns a key-value mapping associated with the least key greater than or equal to the given key, or `null` if there is no such entry.
CeilingKey(Object)
Clear()	To be added (Inherited from AbstractMap)
Clone()	Returns a shallow copy of this `ConcurrentSkipListMap` instance.
Comparator()	Returns the comparator used to compare keys in this sorted map, or null if the natural ordering is in use.
Compute(Object, IBiFunction)	Attempts to compute a mapping for the specified key and its current mapped value (or `null` if there is no current mapping).
ComputeIfAbsent(Object, IFunction)	If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map unless `null`.
ComputeIfPresent(Object, IBiFunction)	If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.

LowerKey(Object)
Merge(Object, Object, IBiFunction)	If the specified key is not already associated with a value, associates it with the given value.
