In luncene 4.3 AtomicReader has this interface public abstract NumericDocValues getNumericDocValues(String field) throwsIOException
If I get a NumericDocValues of one field from a reader. NumericDocValues has get interface. /** * Returns the numeric value for the specified document ID. * @param docID document ID to lookup * @return numeric value */ public abstract long get(int docID); I want to know what will be returned if the input docID is not a valid id, for examples: 1. the docID beyonds the reader scope 2. the doc with this docID is already deleted 2. the doc with this docID doesn't has the field In one word, how can I check if the return value is valid.
