示例1: getTermsEnum
/** Return a {@link TermsEnum} intersecting the provided {@link Terms}
* with the terms accepted by this automaton. */
public TermsEnum getTermsEnum(Terms terms) throws IOException {
switch(type) {
case NONE:
return TermsEnum.EMPTY;
case ALL:
return terms.iterator(null);
case SINGLE:
return new SingleTermsEnum(terms.iterator(null), term);
case PREFIX:
// TODO: this is very likely faster than .intersect,
// but we should test and maybe cutover
return new PrefixTermsEnum(terms.iterator(null), term);
case NORMAL:
return terms.intersect(this, null);
default:
// unreachable
throw new RuntimeException("unhandled case");
}
}
示例2: getTermsEnum
@Override @SuppressWarnings("unchecked")
protected TermsEnum getTermsEnum(final Terms terms, AttributeSource atts) throws IOException {
// very strange: java.lang.Number itself is not Comparable, but all subclasses used here are
if (min != null && max != null && ((Comparable<T>) min).compareTo(max) > 0) {
return TermsEnum.EMPTY;
}
return new NumericRangeTermsEnum(terms.iterator(null));
}
示例3: getTermsEnum
