Re: [icu-design] ICU4J API Proposal: Add isTender() method to CurrencyInfo (#9508)

I wonder if the name isLegalTender(...) might make it a bit more self 
documenting.

Subject:        [icu-design] ICU4J API Proposal: Add isTender() method to 
CurrencyInfo (#9508)



I would like to propose the following API for: ICU 51.
Please provide feedback by: Tuesday, 2012-11-27 (Proposed ICU PMC review 
on 2012-11-28)
Designated API reviewer: Mark Davis
Ticket: http://bugs.icu-project.org/trac/ticket/9508

Currently one can fetch only the currencies used as tender using 
ICUCurrencyMetaInfo.currencyInfo(CurrencyFilter.now()). Using 
ICUCurrencyMetaInfo.currencyInfo(CurrencyFilter.all()) gets all 
currencies, and there is not a trivial way to determine whether or not a 
particular currency is used as tender.

I propose adding isTender() to the CurrencyMetaInfo.CurrencyInfo class for 
ICU4J 51 as below -

/**
 * Determine whether or not a Currency is used as tender right now.
 */
public boolean isTender() {
}

/**
 * Determine whether or not a Currency was ever used as tender since a 
given date
 */
public boolean isTender(java.util.Date fromDate) {
}

/**
 * Determine whether or not a Currency was ever used as tender within some 
date range.
 */
public boolean isTender(java.util.Date fromDate, java.util.Date toDate) {
}

Thanks,
Travis
