All Implemented Interfaces:

Changeable
```
public class SampleData
extends AbstractChangeable
```
This class holds the logic need to determine if sample data needs to be loaded or re-loaded based upon changes to the data configuration. It is shared by the design and preview panels, so that sample data is loaded as infrequently as possible.
It is used by calling update() when a panel is displayed, and then responding to the state of the sample data by listening for changes.

                  ResourcePath resourceId,
                  ReportResource report)
```
- Method Detail
  - getErrors
```
public java.util.List<java.lang.String> getErrors()
```
    Returns a list of any errors incurred during the collection of Data for a report. Returns an empty List if no errors are found.
    
    Returns:
    
    list containing errors, empty List (non-null) if errorless.
  - isLoading
```
public boolean isLoading()
```
  - getLoadedSampleData
```
public SampleDataSchema getLoadedSampleData()
```
  - update
```
public void update()
```
    Checks to see whether or not the sample data which was previously loaded (if any) is up-to-date. Eventually will fire a state change - either immediately if the already loaded data is still good, or later if the data needs to be fetched.
  - forceUpdate
```
public void forceUpdate()
```
    Used by the ReportingResourceEditor to force updating when the report path changes.
