Method Detail

intersect

public TermsEnum intersect(CompiledAutomaton automaton,
                           BytesRef bytes)
                    throws IOException

Description copied from class: Terms

Returns a TermsEnum that iterates over all terms that are accepted by the provided CompiledAutomaton. If the startTerm is provided then the returned enum will only accept terms > startTerm, but you still must call next() first to get to the first term. Note that the provided startTerm must be accepted by the automaton.

NOTE: the returned TermsEnum cannot seek

.

Overrides:

intersect in class Terms

Throws:

IOException

getMin

public BytesRef getMin()
                throws IOException

Description copied from class: Terms

Returns the smallest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.

Overrides:

getMin in class Terms

Throws:

IOException

getMax

public BytesRef getMax()
                throws IOException

Description copied from class: Terms

Returns the largest term (in lexicographic order) in the field. Note that, just like other term measures, this measure does not take deleted documents into account. This returns null when there are no terms.

Overrides:

getMax in class Terms

Throws:

IOException

iterator

public TermsEnum iterator(TermsEnum reuse)
                   throws IOException

Description copied from class: Terms

Returns an iterator that will step through all terms. This method will not return null. If you have a previous TermsEnum, for example from a different field, you can pass it for possible reuse if the implementation can do so.

Overrides:

iterator in class FilterAtomicReader.FilterTerms

Throws:

IOException
