it.unimi.dsi.mg4j.search.visitor.AbstractDocumentIteratorVisitor

An abstract implementation of a {@link it.unimi.dsi.mg4j.search.visitor.DocumentIteratorVisitor} withoutreturn values.

This implementation is hardwired to {@link Boolean}, returns always true on {@link #visitPre(DocumentIterator)}, returns {@link Boolean#TRUE} on all internal nodes if no subnode returns null,returns {@link Boolean#TRUE} on {@linkplain TrueDocumentIterator true}/ {@linkplain FalseDocumentIterator false} document iterators,returns null on calls to {@link #newArray(int)}, and delegates {@link #visit(MultiTermIndexIterator)} to {@link DocumentIteratorVisitor#visit(IndexIterator)}.
