accept
protected boolean accept(BindingSet bindings) throws QueryEvaluationException
Description copied from class:FilterIteration
Tests whether or not the specified object should be returned by this Iteration. All objects from the wrapped Iteration pass through this method in the same order as they are coming from the wrapped Iteration.- Specified by:
accept
in classFilterIteration<BindingSet>
- Parameters:
bindings
- The object to be tested.- Returns:
- true if the object should be returned, false otherwise.
- Throws:
QueryEvaluationException
