Method Details

walk

void walk(BiPredicate<? super ItemPath,Boolean> descendPredicate,
 Predicate<? super ItemPath> consumePredicate,
 Consumer<? super Item<?,?>> itemConsumer)
   throws SchemaException

Walk through hierarchy of containing items based on provided conditions. Caller can provide two types of conditions. One (consumePredicate) is used to decide if currently iterated item should be consumed (by provided itemConsumer). Second (descendPredicate) tells, if walk should descend into currently iterated item. Descending condition is a BiPredicate in order to allow caller decide not just based on item path, but also based on the fact if the item was also consumed (depending on implementation, the results of consumePredicate could be directly passed to the descending condition).

Parameters:

descendPredicate - the BiPredicate which tells whether to descend into current item. Boolean parameter tells whether the item was also consumed or not.

consumePredicate - the Predicate which tells whether to consume current item.

itemConsumer - the consumer to consume item with if it passes the consumePredicate test.

Throws:

SchemaException - when something wrong happen during the walk.
