Public methods

cancelLoad

public void cancelLoad()

Cancels the load.

Loadable implementations should ensure that a currently executing load call will exit reasonably quickly after this method is called. The load call may exit either by returning or by throwing an IOException.

If there is a currently executing load call, then the thread on which that call is being made will be interrupted immediately after the call to this method. Hence implementations do not need to (and should not attempt to) interrupt the loading thread themselves.

Although the loading thread will be interrupted, Loadable implementations should not use the interrupted status of the loading thread in load to determine whether the load has been canceled. This approach is not robust [Internal ref: b/79223737]. Instead, implementations should use their own flag to signal cancelation (for example, using ).

isLoadCompleted

public boolean isLoadCompleted()

Returns whether the chunk has been fully loaded.

load

public void load()

Performs the load, returning on completion or cancellation.

Throws
java.io.IOException

If the input could not be loaded.
