Remarks

A map entry (key-value pair). The Entry may be unmodifiable, or the value may be modifiable if the optional setValue method is implemented. The Entry may be independent of any map, or it may represent an entry of the entry-set view of a map.

Instances of the Map.Entry interface may be obtained by iterating the entry-set view of a map. These instances maintain a connection to the original, backing map. This connection to the backing map is valid only for the duration of iteration over the entry-set view. During iteration of the entry-set view, if supported by the backing map, a change to a Map.Entry's value via the Map.Entry#setValue setValue method will be visible in the backing map. The behavior of such a Map.Entry instance is undefined outside of iteration of the map's entry-set view. It is also undefined if the backing map has been modified after the Map.Entry was returned by the iterator, except through the Map.Entry.setValue method. In particular, a change to the value of a mapping in the backing map might or might not be visible in the corresponding Map.Entry element of the entry-set view.

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
Key	Returns the key.
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)
Value	Returns the value.

Methods

ComparingByKey()	Returns a comparator that compares `Map.Entry` in natural order on key.
ComparingByKey(IComparator)	Returns a comparator that compares `Map.Entry` by key using the given `Comparator`.
ComparingByValue()	Returns a comparator that compares `Map.Entry` in natural order on value.
ComparingByValue(IComparator)	Returns a comparator that compares `Map.Entry` by value using the given `Comparator`.
Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Equals(Object)	Compares the specified object with this entry for equality.
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
GetHashCode()	Returns the hash code value for this map entry.
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
SetValue(Object)	Replaces the value corresponding to this entry with the specified value (optional operation).
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)
GetJniTypeName(IJavaPeerable)
