Attributes

Remarks

Generates a new customized Language Priority List using the given priorityList and map. If the given map is empty, this method returns a copy of the given priorityList.

In the map, a key represents a language range whereas a value is a list of equivalents of it. '*' cannot be used in the map. Each equivalent language range has the same weight value as its original language range.

An example of map:
<b>Key</b>                            <b>Value</b>
                 "zh" (Chinese)                 "zh",
                                                "zh-Hans"(Simplified Chinese)
                 "zh-HK" (Chinese, Hong Kong)   "zh-HK"
                 "zh-TW" (Chinese, Taiwan)      "zh-TW"

The customization is performed after modification using the IANA Language Subtag Registry.

For example, if a user's Language Priority List consists of five language ranges ("zh", "zh-CN", "en", "zh-TW", and "zh-HK"), the newly generated Language Priority List which is customized using the above map example will consists of "zh", "zh-Hans", "zh-CN", "zh-Hans-CN", "en", "zh-TW", and "zh-HK".

"zh-HK" and "zh-TW" aren't converted to "zh-Hans-HK" nor "zh-Hans-TW" even if they are included in the Language Priority List. In this example, mapping is used to clearly distinguish Simplified Chinese and Traditional Chinese.

If the "zh"-to-"zh" mapping isn't included in the map, a simple replacement will be performed and the customized list won't include "zh" and "zh-CN".
