Method Summary

Modifier and Type	Method and Description
int	estimateContextForSureMatch() A number that estimates how many words there must be after a match before we can be (relatively) sure the match is valid.
List<DisambiguationPatternRule>	getAntiPatterns() Overwrite this to avoid false alarms by ignoring these patterns - note that your Rule.match(AnalyzedSentence) method needs to call Rule.getSentenceWithImmunization(org.languagetool.AnalyzedSentence) for this to be used and you need to check AnalyzedTokenReadings.isImmunized()
String	getDescription() A short description of the error this rule can detect, usually in the language of the text that is checked.
String	getId() A string used to identify the rule in e.g. configuration files.
URL	getUrl() An optional URL describing the rule match in more detail.
RuleMatch[]	match(AnalyzedSentence sentence) Check whether the given sentence matches this error rule, i.e. whether it contains the error detected by this rule.

Method Detail

getId

public String getId()

Description copied from class: Rule

A string used to identify the rule in e.g. configuration files. This string is supposed to be unique and to stay the same in all upcoming versions of LanguageTool. It's supposed to contain only the characters A-Z and the underscore.

Specified by:

getId in class Rule

getDescription

public String getDescription()

Description copied from class: Rule

A short description of the error this rule can detect, usually in the language of the text that is checked.

Specified by:

getDescription in class Rule

estimateContextForSureMatch

public int estimateContextForSureMatch()

Description copied from class: Rule

A number that estimates how many words there must be after a match before we can be (relatively) sure the match is valid. This is useful for check-as-you-type, where a match might occur and the word that gets typed next makes the match disappear (something one would obviously like to avoid). Note: this may over-estimate the real context size. Returns -1 when the sentence needs to end to be sure there's a match.

Overrides:

estimateContextForSureMatch in class Rule

getAntiPatterns

public List<DisambiguationPatternRule> getAntiPatterns()

Description copied from class: Rule

Overwrite this to avoid false alarms by ignoring these patterns - note that your Rule.match(AnalyzedSentence) method needs to call Rule.getSentenceWithImmunization(org.languagetool.AnalyzedSentence) for this to be used and you need to check AnalyzedTokenReadings.isImmunized()

Overrides:

getAntiPatterns in class Rule

getUrl

public URL getUrl()

Description copied from class: Rule

An optional URL describing the rule match in more detail. Typically points to a dictionary or grammar website with explanations and examples. Will return null for rules that have no URL.

Overrides:

getUrl in class Rule

match

public RuleMatch[] match(AnalyzedSentence sentence)
                  throws IOException

Description copied from class: Rule

Check whether the given sentence matches this error rule, i.e. whether it contains the error detected by this rule. Note that the order in which this method is called is not always guaranteed, i.e. the sentence order in the text may be different from the order in which you get the sentences (this may be the case when LanguageTool is used as a LibreOffice/OpenOffice add-on, for example). In other words, implementations must be stateless, so that a previous call to this method has no influence on later calls.

Specified by:

match in class Rule

Parameters:

sentence - a pre-analyzed sentence

Returns:

an array of RuleMatch objects

Throws:

IOException
