Constructors

Name Description
JavaSet()

Constructs a new empty instance of HashSet.

JavaSet(IEnumerable)

Initializes a new set and adds the supplied items.

JavaSet(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

Name Description

Handle

The handle to the underlying Android instance.

(Inherited from Object)
IsFixedSize

Gets the reported fixed-size status of the set.

IsReadOnly

Gets the reported read-only status of the set.

IsSynchronized

Gets the reported synchronization state of the set.

Gets the identity hash code assigned to this Java peer by the interop runtime.

(Inherited from Object)
JniManagedPeerState

Gets the state flags last assigned by the runtime.

(Inherited from JavaObject)
JniPeerMembers

Methods

Name Description
Add(Object)

Adds an item to the Java set.

Clear()

Removes all items from the Java set.

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(Object)

Checks whether the Java set contains an item.

CopyTo(Array, Int32)

Copies the set's items 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 collection for a JNI reference to a Java set.

GetEnumerator()

Gets an enumerator for the Java set.

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(Object)

Attempts to remove an item from the Java set.

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(ICollection)

Gets a local JNI reference to a set that represents the collection.

ToString()

Returns a string representation of the object.

(Inherited from Object)
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)
Wait(Int64)

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.

Explicit Interface Implementations

Name Description
IJavaPeerable.Disposed()

Marks this peer as disposed and calls Dispose with disposing set to true.

(Inherited from JavaObject)
IJavaPeerable.Finalized()

Marks this peer as disposed and calls Dispose with disposing set to false.

(Inherited from JavaObject)
IJavaPeerable.JniObjectReferenceControlBlock

Gets the native control-block pointer used by this peer.

(Inherited from JavaObject)
IJavaPeerable.SetJniIdentityHashCode(Int32)

Stores the identity hash code supplied by the runtime.

(Inherited from JavaObject)
IJavaPeerable.SetJniManagedPeerState(JniManagedPeerStates)

Replaces the stored managed peer state flags.

(Inherited from JavaObject)
IJavaPeerable.SetPeerReference(JniObjectReference)

Updates the peer reference and releases a disposed peer's control block when the reference is invalid.

(Inherited from JavaObject)

Extension Methods

Name Description
GetJniTypeName(IJavaPeerable)

Gets the JNI name of the type of the instance self.

JavaAs<TResult>(IJavaPeerable)

Try to coerce self to type TResult, checking that the coercion is valid on the Java side.

JavaCast<TResult>(IJavaObject)

Performs an Android runtime-checked type conversion.

JavaCast<TResult>(IJavaObject)

Reuses a compatible managed peer or obtains a wrapper of the requested type.

TryJavaCast<TResult>(IJavaPeerable, TResult)

Try to coerce self to type TResult, checking that the coercion is valid on the Java side.
