| public void | close()Closes the enumeration to further activity, freeing resources.
actualEnum.close();
currentTerm = null;
actualEnum = null;
|
| public abstract float | difference()Equality measure on the term
|
| public int | docFreq()Returns the docFreq of the current Term in the enumeration.
Returns -1 if no Term matches or all terms have been enumerated.
if (actualEnum == null) return -1;
