Method Detail

getInstance

public static Collator getInstance()

Gets the collator associated with LocalizedString.getDefault().

getInstance

public static Collator getInstance(String s)

Get a (fresh) Collator defined by <locale>:<strength>:<decomposition> Elements of these string can be left away from the right, or left away by leaving empty. For example:

• "da_DK" The Collator associated with danish
• ":IDENTIY The case sensitive Collator associated with the default locale
