Открытые методы

Метод	Описание
Advance ( int target ) : int	Advances to the first match beyond the current whose document number is greater than or equal to a given target. The implementation uses the skipTo() method on the subscorers.
DisjunctionSumScorer ( System subScorers ) : System	Construct a `DisjunctionScorer`, using one as the minimum number of matching subscorers.
DisjunctionSumScorer ( System subScorers, int minimumNrMatchers ) : System	Construct a `DisjunctionScorer`.
DocID ( ) : int
NextDoc ( ) : int
NrMatchers ( ) : int	Returns the number of subscorers matching the current document. Initially invalid, until Next() is called the first time.
Score ( Collector collector, int max, int firstDocID ) : bool	Expert: Collects matching documents in a range. Hook for optimization. Note that Next() must be called once before this method is called for the first time.
Score ( ) : float	Returns the score of the current document matching the query. Initially invalid, until Next() is called the first time.
Score ( Collector collector ) : void	Scores and collects all matching documents.

Защищенные методы

Метод	Описание
AdvanceAfterCurrent ( ) : bool	Advance all subscorers after the current document determined by the top of the `scorerDocQueue`. Repeat until at least the minimum number of subscorers match on the same document and all subscorers are after that document or are exhausted. On entry the `scorerDocQueue` has at least `minimumNrMatchers` available. At least the scorer with the minimum document number will be advanced.

Приватные методы

Метод	Описание
InitScorerDocQueue ( ) : void	Called the first time next() or skipTo() is called to initialize `scorerDocQueue`.

Описание методов

Advance() публичный метод

Advances to the first match beyond the current whose document number is greater than or equal to a given target.
The implementation uses the skipTo() method on the subscorers.

public Advance ( int target ) : int
target	int	The target document number. ///
Результат	int

AdvanceAfterCurrent() защищенный метод

Advance all subscorers after the current document determined by the top of the scorerDocQueue. Repeat until at least the minimum number of subscorers match on the same document and all subscorers are after that document or are exhausted.
On entry the scorerDocQueue has at least minimumNrMatchers available. At least the scorer with the minimum document number will be advanced.

protected AdvanceAfterCurrent ( ) : bool
Результат	bool

DisjunctionSumScorer() публичный метод

Construct a DisjunctionScorer, using one as the minimum number of matching subscorers.

public DisjunctionSumScorer ( System subScorers ) : System
subScorers	System
Результат	System

DisjunctionSumScorer() публичный метод

Construct a DisjunctionScorer.

public DisjunctionSumScorer ( System subScorers, int minimumNrMatchers ) : System
subScorers	System	A collection of at least two subscorers. ///
minimumNrMatchers	int	The positive minimum number of subscorers that should /// match to match this query. /// When minimumNrMatchers is bigger than /// the number of subScorers, /// no matches will be produced. /// When minimumNrMatchers equals the number of subScorers, /// it more efficient to use ConjunctionScorer. ///

NrMatchers() публичный метод

Returns the number of subscorers matching the current document. Initially invalid, until Next() is called the first time.

public NrMatchers ( ) : int
Результат	int

Score() публичный метод

Expert: Collects matching documents in a range. Hook for optimization. Note that Next() must be called once before this method is called for the first time.

public Score ( Collector collector, int max, int firstDocID ) : bool
collector	Collector	The collector to which all matching documents are passed through. ///
max	int	Do not score documents past this. ///
firstDocID	int
Результат	bool

Score() публичный метод

Returns the score of the current document matching the query. Initially invalid, until Next() is called the first time.

public Score ( ) : float
Результат	float

Score() публичный метод

Scores and collects all matching documents.

public Score ( Collector collector ) : void
collector	Collector	The collector to which all matching documents are passed through. /// When this method is used the method should not be used. ///
Результат	void
