Field Detail

keyword

private final java.lang.String keyword

text

private final java.lang.String text

languageTag

private final java.lang.String languageTag

The language tag defined in [RFC-3066] indicates the human language used by the translated keyword and the text. Unlike the keyword, the language tag is case-insensitive. It is an ISO 646.IRV:1991 [ISO 646] string consisting of hyphen-separated words of 1-8 alphanumeric characters each (for example cn, en-uk, no-bok, x-klingon, x-KlInGoN). If the first word is two or three letters long, it is an ISO language code [ISO-639]. If the language tag is empty, the language is unspecified.

translatedKeyword

private final java.lang.String translatedKeyword
