Type Parameters:

T -

All Implemented Interfaces:

IReadOnly, IApiTask<T>, Callable<T>

public abstract class AbstractDelegateRestApiTask<T>
extends AbstractRestApiTask<T>

Base class for delegation patterns where the delegate is an IApiTask. This is necessary in order to pass through the isGRSRequired() and setIndexManager(IIndexManager) method to both the base class and the delegate.

setIndexManager

public void setIndexManager(IIndexManager indexManager)

Description copied from interface: IApiTask

Invoked to inform the task of the index manager before it is executed.

Specified by:

setIndexManager in interface IApiTask<T>

Overrides:

setIndexManager in class AbstractApiTask<T>

Parameters:

indexManager - The index manager.

isGRSRequired

public boolean isGRSRequired()

Description copied from interface: IApiTask

Tasks that create or destroy locatable resources need to write on the global row store (GRS). Such tasks must specify this property. Note that the GRS lock will have the side-effect of serializing all such tasks that write on the GRS index.

Specified by:

isGRSRequired in interface IApiTask<T>

Overrides:

isGRSRequired in class AbstractApiTask<T>
