| Values |
Gets the values of the Java map. |
Methods
| Name | Description |
|---|---|
| Add(K, V) |
Adds a mapping for the key and value. An existing key causes an ArgumentException. |
| Add(KeyValuePair<K,V>) |
Adds a mapping for the pair. An existing key causes an ArgumentException. |
| Add(Object, Object) |
Adds a mapping for the key and value. An existing key causes an ArgumentException. (Inherited from JavaDictionary) |
| Clear() |
Removes all mappings from the Java map. (Inherited from JavaDictionary) |
| Clone() |
Creates and returns a copy of this object. (Inherited from Object) |
| Construct(JniObjectReference, JniObjectReferenceOptions) |
Delegates construction of this peer to the runtime's value manager. (Inherited from JavaObject) |
| Contains(KeyValuePair<K,V>) |
Checks whether the Java map contains the pair's key, without comparing its value. |
| Contains(Object) |
Checks whether the Java map contains a key. (Inherited from JavaDictionary) |
| ContainsKey(K) |
Checks whether the Java map contains a key. |
| CopyTo(Array, Int32) |
Copies the dictionary entries to an array. (Inherited from JavaDictionary) |
| CopyTo(KeyValuePair<K,V>[], Int32) |
Copies the dictionary's key-value pairs to an array. |
| Dispose() |
Releases the resources held by this Java peer. (Inherited from Object) |
| Dispose(Boolean) |
Releases the resources held by this Java peer. (Inherited from Object) |
| DisposeUnlessReferenced() |
Asks the value manager to dispose this peer unless its mapping retains this same managed instance. (Inherited from JavaObject) |
| Equals(Object) |
Tests whether another managed peer refers to the same Java object. (Inherited from JavaObject) |
| Equals(Object) |
Indicates whether some other object is "equal to" this one. (Inherited from Object) |
| FromJniHandle(IntPtr, JniHandleOwnership) |
Gets a managed dictionary for a JNI reference to a Java map. |
| GetEnumerator() |
Gets an enumerator for the dictionary's key-value pairs. |
| GetHashCode() |
Returns a hash code value for the object. (Inherited from Object) |
| JavaFinalize() |
Obsolete.
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) |
| Notify() |
Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object) |
| NotifyAll() |
Wakes up all threads that are waiting on this object's monitor. (Inherited from Object) |
| Remove(K) |
Attempts to remove a mapping from the Java map. |
| Remove(KeyValuePair<K,V>) |
Attempts to remove the mapping for the pair's key, without comparing its value. |
| Remove(Object) |
Removes the mapping for a key from the Java map, if present. (Inherited from JavaDictionary) |
| SetHandle(IntPtr, JniHandleOwnership) |
Sets the Handle property. (Inherited from Object) |
| SetPeerReference(JniObjectReference, JniObjectReferenceOptions) |
Stores a reference value in the control block without creating a JNI reference copy. (Inherited from JavaObject) |
| ToArray<T>() |
Creates a managed array from this Java array wrapper. (Inherited from Object) |
| ToLocalJniHandle(IDictionary<K,V>) |
Gets a local JNI reference to a map that represents the dictionary. |
| ToString() |
Returns a string representation of the object. (Inherited from Object) |
| TryGetValue(K, V) |
Gets the map's result for a key, then checks whether the key is present. |
| UnregisterFromRuntime() |
Unregisters this Java peer from the interop runtime. (Inherited from Object) |
| Wait() |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object) |
| Wait(Int64, Int32) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
