CursorLoader

Kotlin |Java

open class CursorLoader : AsyncTaskLoader<Cursor!>

kotlin.Any
↳	androidx.loader.content.Loader<D>
	↳	androidx.loader.content.AsyncTaskLoader<android.database.Cursor>
		↳	androidx.loader.content.CursorLoader

Static library support version of the framework's android.content.CursorLoader. Used to write apps that run on platforms prior to Android 3.0. When running on Android 3.0 or above, this implementation is still used; it does not try to switch to the framework's implementation. See the framework SDK documentation for a class overview.

Inherited functions

From class Loader

`Unit`	`abandon()` This function will normally be called for you automatically by `LoaderManager` when restarting a Loader. When using a Loader with `LoaderManager`, you must not call this method yourself, or you will conflict with its management of the Loader. Tell the Loader that it is being abandoned. This is called prior to `reset` to have it retain its current data but not report any new data. Must be called from the process's main thread.
`Boolean`	`cancelLoad()` Attempt to cancel the current load task. Must be called on the main thread of the process. Cancellation is not an immediate operation, since the load is performed in a background thread. If there is currently a load in progress, this method requests that the load be canceled, and notes this is the case; once the background thread has completed its work its remaining state will be cleared. If another load request comes in during this time, it will be held until the canceled load is complete.
`Unit`	`commitContentChanged()` Commit that you have actually fully processed a content change that was returned by `takeContentChanged`. This is for use with `rollbackContentChanged()` to handle situations where a load is cancelled. Call this when you have completely processed a load without it being cancelled.
`String`	`dataToString(@Nullable data: D?)` For debugging, converts an instance of the Loader's data class to a string that can be printed. Must handle a null data.
