|
virtual int32_t | compare (int32_t slot1, int32_t slot2) |
| Compare hit at slot1 with hit at slot2.
|
|
virtual int32_t | compareBottom (int32_t doc) |
| Compare the bottom of the queue with doc. This will only invoked after setBottom has been called. This should return the same result as compare(int,int) } as if bottom were slot1 and the new document were slot 2.
|
|
virtual void | setNextReader (const IndexReaderPtr &reader, int32_t docBase) |
| Set a new Reader. All doc correspond to the current Reader.

|
virtual | ~NumericComparator () |
|
virtual void | copy (int32_t slot, int32_t doc) |
| This method is called when a new hit is competitive. You should copy any state associated with this document that will be required for future comparisons, into the specified slot.
|
|
virtual void | setBottom (int32_t slot) |
| Set the bottom slot, ie the "weakest" (sorted last) entry in the queue. When compareBottom is called, you should compare against this slot. This will always be called before compareBottom .
|
|
virtual ComparableValue | value (int32_t slot) |
| Return the actual value in the slot.

virtual void | setScorer (const ScorerPtr &scorer) |
| Sets the Scorer to use in case a document's score is needed.
|
|
virtual | ~LuceneObject () |
|
virtual void | initialize () |
| Called directly after instantiation to create objects that depend on this object being fully constructed.
|
|
virtual LuceneObjectPtr | clone (const LuceneObjectPtr &other=LuceneObjectPtr()) |
| Return clone of this object.
|
|
virtual int32_t | hashCode () |
| Return hash code for this object.
|
|
virtual bool | equals (const LuceneObjectPtr &other) |
| Return whether two objects are equal.
|
|
virtual int32_t | compareTo (const LuceneObjectPtr &other) |
| Compare two objects.
|
|
virtual String | toString () |
| Returns a string representation of the object.
|
|
virtual | ~LuceneSync () |
|
virtual SynchronizePtr | getSync () |
| Return this object synchronize lock.
|
|
virtual LuceneSignalPtr | getSignal () |
| Return this object signal.
|
|
virtual void | lock (int32_t timeout=0) |
| Lock this object using an optional timeout.
|
|
virtual void | unlock () |
| Unlock this object.
|
|
virtual bool | holdsLock () |
| Returns true if this object is currently locked by current thread.
|
|
virtual void | wait (int32_t timeout=0) |
| Wait for signal using an optional timeout.
|
|
virtual void | notifyAll () |
| Notify all threads waiting for signal.
|
|
Parses field's values as double (using FieldCache#getDoubles
and sorts by ascending value.

|
|
virtual |
Compare the bottom of the queue with doc. This will only invoked after setBottom has been called. This should return the same result as compare(int,int)
} as if bottom were slot1 and the new document were slot 2.
For a search that hits many results, this method will be the hotspot (invoked by far the most frequently).
- Parameters
-
- Returns
- any N < 0 if the doc's value is sorted after the bottom entry (not competitive), any N > 0 if the doc's value is sorted before the bottom entry and 0 if they are equal.
