Syntax

public abstract class MultiFunction : ValueSource

Constructors

MultiFunction(IList<ValueSource>)

Abstract parent class for ValueSource implementations that wrap multiple ValueSources and apply their own logic.

Declaration

protected MultiFunction(IList<ValueSource> sources)

Parameters

Type	Name	Description
IList<ValueSource>	sources

Fields

m_sources

Abstract parent class for ValueSource implementations that wrap multiple ValueSources and apply their own logic.

Declaration

protected readonly IList<ValueSource> m_sources

Field Value

Type	Description
IList<ValueSource>

Properties

Name

Abstract parent class for ValueSource implementations that wrap multiple ValueSources and apply their own logic.

Declaration

protected abstract string Name { get; }

Property Value

Type	Description
string

Methods

CreateWeight(IDictionary, IndexSearcher)

Implementations should propagate CreateWeight to sub-ValueSources which can optionally store weight info in the context. The context object will be passed to GetValues() where this info can be retrieved.

Declaration

public override void CreateWeight(IDictionary context, IndexSearcher searcher)

Parameters

Type	Name	Description
IDictionary	context
IndexSearcher	searcher

Overrides

ValueSource.CreateWeight(IDictionary, IndexSearcher)

Equals(object)

Determines whether the specified object is equal to the current object.

Declaration

public override bool Equals(object o)

Parameters

Type	Name	Description
object	o

Returns

Type	Description
bool	true if the specified object is equal to the current object; otherwise, false.

Overrides

ValueSource.Equals(object)

GetDescription()

description of field, used in Explain()

Declaration

public override string GetDescription()

Returns

Type	Description
string

Overrides

ValueSource.GetDescription()

GetDescription(string, IList<ValueSource>)

Abstract parent class for ValueSource implementations that wrap multiple ValueSources and apply their own logic.

Declaration

public static string GetDescription(string name, IList<ValueSource> sources)

Parameters

Type	Name	Description
string	name
IList<ValueSource>	sources

Returns

Type	Description
string

GetHashCode()

Serves as the default hash function.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	A hash code for the current object.

Overrides

ValueSource.GetHashCode()

ToString(string, FunctionValues[], int)

Abstract parent class for ValueSource implementations that wrap multiple ValueSources and apply their own logic.

Declaration

public static string ToString(string name, FunctionValues[] valsArr, int doc)

Parameters

Type	Name	Description
string	name
FunctionValues[]	valsArr
int	doc

Returns

Type	Description
string

ValsArr(IList<ValueSource>, IDictionary, AtomicReaderContext)

Abstract parent class for ValueSource implementations that wrap multiple ValueSources and apply their own logic.

Declaration

public static FunctionValues[] ValsArr(IList<ValueSource> sources, IDictionary fcontext, AtomicReaderContext readerContext)

Parameters

Type	Name	Description
IList<ValueSource>	sources
IDictionary	fcontext
AtomicReaderContext	readerContext

Returns

Type	Description
FunctionValues[]
