All Implemented Interfaces:

Task

public class OneTierRequestTask
extends AbstractResultSetBinaryResultsTask

This Task provides the following functionality: it can retrieve the results associated with a Report Services document in binary format. If the document has not finished executing, it can poll for the results (observing a maximum wait time and a polling frequency value). Once the document is ready, the task will fetch the binary data of the document. Currently this task is used by the dashboards in flash format

Since:

MicroStrategy Web 9.0.0
