JLanguageTool (languagetool-parent 5.4 API)

java.lang.Object
- org.languagetool.JLanguageTool

Direct Known Subclasses:

MultiThreadedJLanguageTool
```
public class JLanguageTool
extends Object
```
The main class used for checking text against different rules:
- built-in Java rules (for English: a vs. an, whitespace after commas, ...)
- built-in pattern rules loaded from external XML files (usually called grammar.xml)
- your own implementation of the abstract Rule classes added with addRule(Rule)
You will probably want to use the sub class MultiThreadedJLanguageTool for best performance.
Thread-safety: this class is not thread safe. Create one instance per thread, but create the language only once (e.g. new AmericanEnglish()) and use it for all instances of JLanguageTool.

```
The main check method. Tokenizes the text into sentences and matches these sentences against all currently active rules.

Parameters:

annotatedText - The text to be checked, created with AnnotatedTextBuilder. Call this method with the complete text to be checked. If you call it repeatedly with smaller chunks like paragraphs or sentence, those rules that work across paragraphs/sentences won't work (their status gets reset whenever this method is called).

tokenizeText - If true, then the text is tokenized into sentences. Otherwise, it is assumed it's already tokenized, i.e. it is only one sentence

paraMode - Uses paragraph-level rules only if true.

Returns:

a List of RuleMatch objects, describing potential errors in the text

Throws:

IOException

Get all rules for the current language that are built-in or that have been added using addRule(Rule). Please note that XML rules that are grouped will appear as multiple rules with the same id. To tell them apart, check if they are of type AbstractPatternRule, cast them to that type and call their AbstractPatternRule.getSubId() method.

Returns:

a List of Rule objects

getAllActiveRules
