org.apache.lucene.index .TermEnum

All known Subclasses:   org.apache.lucene.search .FilteredTermEnum,  org.apache.lucene.index .SegmentTermEnum,
TermEnum
abstract public class TermEnum (Code)
Abstract class for enumerating terms.
Term enumerations are always ordered by Term.compareTo(). Each term in the enumeration is greater than all that precede it.

Method Summary
abstract public void close()
     Closes the enumeration to further activity, freeing resources.
abstract public int docFreq()
     Returns the docFreq of the current Term in the enumeration.
abstract public boolean next()
     Increments the enumeration to the next element.
public boolean skipTo(Term target)
     Skips terms to the first beyond the current whose value is greater or equal to target.
abstract public Term term()
     Returns the current Term in the enumeration.

Method Detail
close
abstract public void close() throws IOException(Code)
Closes the enumeration to further activity, freeing resources.

docFreq
abstract public int docFreq()(Code)
Returns the docFreq of the current Term in the enumeration.

next
abstract public boolean next() throws IOException(Code)
Increments the enumeration to the next element. True if one exists.

skipTo
public boolean skipTo(Term target) throws IOException(Code)
Skips terms to the first beyond the current whose value is greater or equal to target.
Returns true iff there is such an entry.
Behaves as if written:
public boolean skipTo(Term target) { do { if (!next()) return false; } while (target > term()); return true; }
Some implementations are considerably more efficient than that.

term
abstract public Term term()(Code)
Returns the current Term in the enumeration.
