com.borland.dx.dataset.LoadCancel
Methods
Implemented by DataSetData, TextDataFile, JdbcProvider, OracleProcedureProvider, ProcedureProvider, QueryProvider
This interface is generally called internally by a DataSet
component's
cancelLoading()
method, however, you might implement this interface if you are
writing your own loader using the
startLoading(com.borland.dx.dataset.LoadCancel, int, boolean)
, loadRow()
, and endLoading()
method of a
StorageDataSet
.
A QueryDataSet
has a cancelLoading()
method. When you call the cancelLoading()
method, the data set asks if it supports the LoadCancel
interface. If so, the cancelLoading()
method then calls the LoadCancel
interface's cancelLoad()
method to cancel a load operation. This class is especially useful for asynchronous queries and can also be used to cancel a TextDataFile
load operation.
public void cancelLoad()Cancels a load operation on a
DataSet
