Method Detail

getNextFacets

public abstract void getNextFacets(List<CategoryPath> facets)
                            throws NoMoreDataException,
                                   IOException
Fills the next facets content items in the given list. Implementations must account for multi-threading, as multiple threads can call this method simultaneously.

Throws:
NoMoreDataException
IOException

resetInputs

public void resetInputs()
                 throws IOException
Description copied from class: ContentItemsSource
Resets the input for this content source, so that the test would behave as if it was just started, input-wise.

NOTE: the default implementation resets the number of bytes and items generated since the last reset, so it's important to call super.resetInputs in case you override this method.

Overrides:
resetInputs in class ContentItemsSource
Throws:
IOException
