Method Documentation

◆ didComplete:

- (void) didComplete: (BOOL)  everStarted

Subclasses should override if they want to run some code once the operation is completed. This function is guaranteed to only be called once. everStarted will be NO if the operation was canceled before it could be started.

Since
100

Extends class AGSOperationBase.

◆ doCancel

- (void) doCancel

Subclasses can override to do the actual work to cancel the operation. Once cancel is complete, call doneExecuting. For operations that do not do all of their work in doExecute, it makes sense to override this and cancel any network connections, etc. Then when the cancel is complete, you call doneExecuting. For operations where the work is all done in doExecute they shouldn't need to override this, you should just check the isCanceled property throughout the execution of the operation and if it is canceled then call doneExecuting and return.

◆ doExecute

- (void) doExecute

Subclasses should override to do the actual execution of the operation. Once done, call doneExecuting.

Since

Extends class AGSOperationBase.

◆ doneExecuting

- (void) doneExecuting

Subclasses should call this when they are done executing or done cancelling.

Property Documentation

◆ startAsynchronously

- (BOOL) startAsynchronously
readwritenonatomicassign

Subclasses can set this if they want to be started asynchronously or not. If an operation does most or all of it's work in doExecute it should set this to YES. If an operation returns quickly from doExecute and does all of it's work on a different queue then this value should be NO. The default value is YES.
