CreateLinkOperation.getLink()

runImpl

public void runImpl()
             throws OperationNotSupportedException

Description copied from class: AbstractOperation

The actual run() implementation goes in this method. Setting the last run exception and setting hasRun to true is not required by this method as it is handled by the run() method in this class.

If this method completes successfully (i.e. without throwing an exception), the last run exception is set to null indicating no exception occurred and subsequent calls to hasRun() will return true.

If this method throws an exception, the last run exception is filled in and hasRun() subsequent calls to hasRun() will return false.

Specified by:

runImpl in class AbstractOperation

OperationNotSupportedException
