Specified by:

clone in class Query

isEmptyQuery

public boolean isEmptyQuery()

Overrides:

isEmptyQuery in class AbstractLeafQuery

Returns:

true if this query is now essentially "empty" (doesn't affect query logic at all) and can now be removed from the query tree. This can happen, for example, if all child queries were removed and the query logic depends on having at least one child query.
