C# Class Lucene.Net.Analysis.MockAnalyzer

Analyzer for testing

this analyzer is a replacement for Whitespace/Simple/KeywordAnalyzers for unit tests. If you are testing a custom component such as a queryparser or analyzer-wrapper that consumes analysis streams, its a great idea to test it with this analyzer instead. MockAnalyzer has the following behavior:

By default, the assertions in MockTokenizer are turned on for extra checks that the consumer is consuming properly. These checks can be disabled with #setEnableChecks(boolean).
Payload data is randomly injected into the stream for more thorough testing of payloads.

Public Methods

Method	Description
CreateComponents ( string fieldName, TextReader reader ) : TokenStreamComponents
GetOffsetGap ( string fieldName ) : int	Get the offset gap between tokens in fields if several fields with the same name were added.
GetPositionIncrementGap ( string fieldName ) : int
MockAnalyzer ( Random random ) : System	Create a Whitespace-lowercasing analyzer with no stopwords removal. Calls {@link #MockAnalyzer(Random, CharacterRunAutomaton, boolean, CharacterRunAutomaton) MockAnalyzer(random, MockTokenizer.WHITESPACE, true, MockTokenFilter.EMPTY_STOPSET, false}).
MockAnalyzer ( Random random, CharacterRunAutomaton runAutomaton, bool lowerCase ) : System	Calls {@link #MockAnalyzer(Random, CharacterRunAutomaton, boolean, CharacterRunAutomaton) MockAnalyzer(random, runAutomaton, lowerCase, MockTokenFilter.EMPTY_STOPSET, false}).
MockAnalyzer ( Random random, CharacterRunAutomaton runAutomaton, bool lowerCase, CharacterRunAutomaton filter ) : System	Creates a new MockAnalyzer.

Method Details

CreateComponents() public method

public CreateComponents ( string fieldName, TextReader reader ) : TokenStreamComponents
fieldName	string
reader	System.IO.TextReader
return	TokenStreamComponents

GetOffsetGap() public method

Get the offset gap between tokens in fields if several fields with the same name were added.

public GetOffsetGap ( string fieldName ) : int
fieldName	string	Currently not used, the same offset gap is returned for each field.
return	int

GetPositionIncrementGap() public method

return	int

MockAnalyzer() public method

Create a Whitespace-lowercasing analyzer with no stopwords removal.

Calls {@link #MockAnalyzer(Random, CharacterRunAutomaton, boolean, CharacterRunAutomaton) MockAnalyzer(random, MockTokenizer.WHITESPACE, true, MockTokenFilter.EMPTY_STOPSET, false}).

public MockAnalyzer ( Random random ) : System
random	System.Random
return	System

MockAnalyzer() public method

Calls {@link #MockAnalyzer(Random, CharacterRunAutomaton, boolean, CharacterRunAutomaton) MockAnalyzer(random, runAutomaton, lowerCase, MockTokenFilter.EMPTY_STOPSET, false}).

public MockAnalyzer ( Random random, CharacterRunAutomaton runAutomaton, bool lowerCase ) : System
random	System.Random
runAutomaton	CharacterRunAutomaton
lowerCase	bool
return	System

MockAnalyzer() public method

Creates a new MockAnalyzer.

public MockAnalyzer ( Random random, CharacterRunAutomaton runAutomaton, bool lowerCase, CharacterRunAutomaton filter ) : System
random	System.Random	Random for payloads behavior
runAutomaton	CharacterRunAutomaton	DFA describing how tokenization should happen (e.g. [a-zA-Z]+)
lowerCase	bool	true if the tokenizer should lowercase terms
filter	CharacterRunAutomaton	DFA describing how terms should be filtered (set of stopwords, etc)
return	System
