Methods

Abandon() Abandon()

This function will normally be called for you automatically by LoaderManager when restarting a Loader.

CancelLoad() CancelLoad()

Attempt to cancel the current load task.

Clone() Clone()

Creates and returns a copy of this Object.

(Inherited from Object)
CommitContentChanged() CommitContentChanged()

Commit that you have actually fully processed a content change that was returned by TakeContentChanged().

DataToString(Object) DataToString(Object)
DeliverCancellation() DeliverCancellation()

Informs the registered Loader.IOnLoadCanceledListener that the load has been canceled.

DeliverResult(Object) DeliverResult(Object)
Dispose() Dispose() Inherited from Object
Dispose(Boolean) Dispose(Boolean) Inherited from Object
Dump(String, FileDescriptor, PrintWriter, String[]) Dump(String, FileDescriptor, PrintWriter, String[])

Print the Loader's state into the given stream.

DumpAsync(String, FileDescriptor, PrintWriter, String[]) DumpAsync(String, FileDescriptor, PrintWriter, String[])
Equals(Object) Equals(Object)

Compares this instance with the specified object and indicates if they are equal.

(Inherited from Object)
ForceLoad() ForceLoad()

Force an asynchronous load.

GetHashCode() GetHashCode()

Returns an integer hash code for this object.

(Inherited from Object)
JavaFinalize() JavaFinalize()

Invoked when the garbage collector has detected that this instance is no longer reachable.

(Inherited from Object)
Notify() Notify()

Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

(Inherited from Object)
NotifyAll() NotifyAll()

Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.

(Inherited from Object)
OnAbandon() OnAbandon()

Subclasses implement this to take care of being abandoned.

OnCancelLoad() OnCancelLoad()

Subclasses must implement this to take care of requests to CancelLoad().

OnContentChanged() OnContentChanged()

Called when Loader.ForceLoadContentObserver detects a change.

OnForceLoad() OnForceLoad()

Subclasses must implement this to take care of requests to ForceLoad().

OnReset() OnReset()

Subclasses must implement this to take care of resetting their loader, as per Reset().

OnStartLoading() OnStartLoading()

Subclasses must implement this to take care of loading their data, as per StartLoading().

OnStopLoading() OnStopLoading()

Subclasses must implement this to take care of stopping their loader, as per StopLoading().

RegisterListener(Int32, Loader+IOnLoadCompleteListener) RegisterListener(Int32, Loader+IOnLoadCompleteListener)
RegisterOnLoadCanceledListener(Loader+IOnLoadCanceledListener) RegisterOnLoadCanceledListener(Loader+IOnLoadCanceledListener)
Reset() Reset()

This function will normally be called for you automatically by LoaderManager when destroying a Loader.

RollbackContentChanged() RollbackContentChanged()

Report that you have abandoned the processing of a content change that was returned by TakeContentChanged() and would like to rollback to the state where there is again a pending content change.

SetHandle(IntPtr, JniHandleOwnership) SetHandle(IntPtr, JniHandleOwnership)

Sets the Handle property.

(Inherited from Object)
StartLoading() StartLoading()

This function will normally be called for you automatically by LoaderManager when the associated fragment/activity is being started.

StopLoading() StopLoading()

This function will normally be called for you automatically by LoaderManager when the associated fragment/activity is being stopped.

TakeContentChanged() TakeContentChanged()

Take the current flag indicating whether the loader's content had changed while it was stopped.

Wait() Wait()

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

(Inherited from Object)
Wait(Int64) Wait(Int64)

Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.

(Inherited from Object)
Wait(Int64, Int32) Wait(Int64, Int32)
