IUserDataHandler Interface

Definition

When associating an object to a key on a node using Node.setUserData() the application can provide a handler that gets called when the node the object is associated to is being cloned, imported, or renamed.

[Android.Runtime.Register("org/w3c/dom/UserDataHandler", "", "Org.W3c.Dom.IUserDataHandlerInvoker")]
public interface IUserDataHandler : Android.Runtime.IJavaObject, IDisposable, Java.Interop.IJavaPeerable

Remarks

When associating an object to a key on a node using Node.setUserData() the application can provide a handler that gets called when the node the object is associated to is being cloned, imported, or renamed. This can be used by the application to implement various behaviors regarding the data it associates to the DOM nodes. This interface defines that handler.

Fields

NodeAdopted

The node is adopted, using Document.adoptNode().

NodeCloned

The node is cloned, using Node.cloneNode().

NodeDeleted

The node is deleted.

NodeImported

The node is imported, using Document.importNode().

NodeRenamed

The node is renamed, using Document.renameNode().

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)
PeerReference

Returns a JniObjectReference of the wrapped Java object instance.

(Inherited from IJavaPeerable)

Methods

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)
Finalized()

Called when the instance has been finalized.

(Inherited from IJavaPeerable)
handleData(Int16, String, Object, INode, INode)

This method is called whenever the node for which this handler is registered is imported or cloned.

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)
UnregisterFromRuntime()

Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations.

(Inherited from IJavaPeerable)
