Properties

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

Methods

Clone()	Creates and returns a copy of this object. (Inherited from Object)
Close()	Close the backing `FileDescriptor` of this SharedMemory instance.
Create(String, Int32)	Creates an anonymous SharedMemory instance with the provided debug name and size.
DescribeContents()
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
FromFileDescriptor(ParcelFileDescriptor)	Creates an instance from existing shared memory passed as `ParcelFileDescriptor`.
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
Map(Int32, Int32, Int32)	Creates an mmap of the SharedMemory with the specified prot, offset, and length.
MapReadOnly()	Creates a read-only mapping of the entire shared memory region.
MapReadWrite()	Creates a read/write mapping of the entire shared memory region.
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)
SetHandle(IntPtr, JniHandleOwnership)	Sets the Handle property. (Inherited from Object)
SetProtect(Int32)	Sets the protection on the shared memory to the combination specified in prot, which is either a bitwise-or'd combination of `android.system.OsConstants#PROT_READ`, `android.system.OsConstants#PROT_WRITE`, `android.system.OsConstants#PROT_EXEC` from `android.system.OsConstants`, or `android.system.OsConstants#PROT_NONE`, to remove all further access.
ToArray<T>()	(Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
Unmap(ByteBuffer)	Unmaps a buffer previously returned by `#map(int, int, int)`.
UnregisterFromRuntime()	(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. (Inherited from Object)
WriteToParcel(Parcel, ParcelableWriteFlags)

Explicit Interface Implementations

IJavaPeerable.Disposed()	(Inherited from Object)

IJavaPeerable.SetJniIdentityHashCode(Int32)	(Inherited from Object)
IJavaPeerable.SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from Object)
IJavaPeerable.SetPeerReference(JniObjectReference)	(Inherited from Object)

Extension Methods

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