All Implemented Interfaces:

WordRule

public class IrregularMappingRule
extends AbstractRegexReplacementRule

A rule for specifying an irregular inflection using a combination of a map of singular to plural forms and a regular expression replacement.

Subclasses can implement replace(java.util.regex.Matcher) to perform the actual replacement, which by default uses the map to substitute a plural form for the corresponding singular form found in group 0 of the regular expression match.

                    java.lang.String regex)

Construct a rule using a regular expression and irregular forms map.

Parameters:

wordMappings - The map of singular to plural forms.

regex - The regular expression used to match words. Match information is available to subclasses in the replace(java.util.regex.Matcher) method.

Method Detail

replace

public java.lang.String replace(java.util.regex.Matcher m)

Description copied from class: AbstractRegexReplacementRule

replace in class AbstractRegexReplacementRule

Parameters:

m - The matcher used to match the word.

Returns:

The transformed word.

toMap

public static java.util.Map<java.lang.String,java.lang.String> toMap(java.lang.String[][] wordMappings)

Convert an array of String array mapping pairs into a map.

Parameters:

wordMappings - Two-dimensional array of strings. First entry is singular form, second entry is plural form.

Returns:

A map of singular to plural forms.
