Syntax

public abstract class TokenFilterFactory : AbstractAnalysisFactory

Constructors

TokenFilterFactory(IDictionary<String, String>)

Initialize this factory via a set of key-value pairs.

Declaration

protected TokenFilterFactory(IDictionary<string, string> args)

Parameters

Type	Name	Description
System.Collections.Generic.IDictionary<System.String, System.String>	args

Properties

AvailableTokenFilters

returns a list of all available tokenfilter names from the host project's referenced assemblies

Declaration

public static ICollection<string> AvailableTokenFilters { get; }

Property Value

Type	Description
System.Collections.Generic.ICollection<System.String>

Methods

Create(TokenStream)

Transform the specified input Lucene.Net.Analysis.TokenStream

Declaration

public abstract TokenStream Create(TokenStream input)

Parameters

Type	Name	Description
Lucene.Net.Analysis.TokenStream	input

Returns

Type	Description
Lucene.Net.Analysis.TokenStream

ForName(String, IDictionary<String, String>)

looks up a tokenfilter by name from the host project's referenced assemblies

Declaration

public static TokenFilterFactory ForName(string name, IDictionary<string, string> args)

Parameters

Type	Name	Description
System.String	name
System.Collections.Generic.IDictionary<System.String, System.String>	args

Returns

Type	Description
TokenFilterFactory

LookupClass(String)

looks up a tokenfilter class by name from the host project's referenced assemblies

Declaration

public static Type LookupClass(string name)

Parameters

Type	Name	Description
System.String	name

Returns

Type	Description
System.Type

ReloadTokenFilters()

Reloads the factory list. Changes to the factories are visible after the method ends, all iterators (AvailableTokenFilters,...) stay consistent.

NOTE: Only new factories are added, existing ones are never removed or replaced.

This method is expensive and should only be called for discovery of new factories on the given classpath/classloader!

Declaration

public static void ReloadTokenFilters()
