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 | 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 | setNextReader (const IndexReaderPtr &reader, int32_t docBase) |
Set a new Reader. All doc correspond to the current Reader. | |

virtual int32_t | compare (int32_t slot1, int32_t slot2) |
Compare hit at slot1 with hit at slot2. | |
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 . | |

Return the actual value in the slot. | |

virtual LuceneObjectPtr | clone (const LuceneObjectPtr &other=LuceneObjectPtr()) |
Return clone of this object. | |

Return hash code for this object. | |

Return whether two objects are equal. | |

Unlock this object. | |

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 |
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).
doc | that was hit |
Reimplemented from Lucene::NumericComparator< int32_t >.
|
virtual |
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.
slot | which slot to copy the hit to |
doc | docID relative to current reader |
Reimplemented from Lucene::NumericComparator< int32_t >.
|
inlinevirtual |
Reimplemented from Lucene::FieldComparator.
|
virtual |
Set a new Reader. All doc correspond to the current Reader.
reader | current reader |
