Class PartialPosTagFilter

java.lang.Object

org.languagetool.rules.PartialPosTagFilter

All Implemented Interfaces:

RuleFilter

public abstract class PartialPosTagFilter
extends Object
implements RuleFilter

Filters rule matches so that only matches are kept where a part of the token has a given POS tag. Expects these arguments:

• no: an integer of the matching 'token' position to be considered. Starts with 1.
• regexp: the regular expression to specify the part of the token to be considered. For example, (?:in|un)(.*) will consider the part of the token that comes after 'in' or 'un'. Note that always the first group is considered, so if you need more parenthesis you need to use non-capturing groups (?:...), as in the example.
• postag_regexp: a regular expression to match the POS tag of the part of the word, e.g. VB.? to match any verb in English.
